Quartz Lake Loop Hike

A trip through old growth forest to three crystal clear mountain lakes with views of magnificent peaks.

Located in the remote northwest region of Glacier National Park near Polebridge, Montana, this hike will take you through old growth forest to three crystal clear mountain lakes with views of magnificent peaks. I think the drive to get there is worth it.

The Inside North Fork Road (Glacier Route Seven) is closed between Camas and Logging Creeks. So, that leaves two options. From Columbia Falls, drive the North Fork Road for 35 miles (56.3 km) to Polebridge. This route is mostly gravel, and it can be a bone-jarring, dusty ride. The second choice is to drive through West Glacier into the park and out Camas Road. That leaves only about 14 miles (22.5 km) of mostly gravel, which is usually in a little better shape than the North Fork Road south of there.

As any local knows, you cannot visit this region of Glacier without first stopping at the Polebridge Mercantile and bakery located just outside the park. There will probably be someone around by 7 AM. Early is desirable because their fresh baked goods have a quasi-cult following. If you arrive around dinner time, check out the Northern Lights Saloon and Cafe next to the Merc. I doubt that they will disappoint you.

By the way, if the Mercantile seems old, it is. Bill Adair built the Merc in 1914. Local folks back then knew it merely as Adair’s. Bill and his wife ran the store and lived in their homestead cabin, which is now the Northern Lights Saloon and Cafe. These buildings are now part of the W.L. Adair General Mercantile Historic District which was placed on the National Register of Historic Places in 1983.¹

A few other things of which you should be aware. Polebridge and the surrounding area are off the grid. There is no cell service or Wi-Fi. However, there is a computer with the Internet in the store that the owner may let you use. And there is no public garbage service.

Quartz Lake Loop Trailhead

The hike begins near the Bowman Lake Campground and picnic area 6.3 miles (10.1 km) from Polebridge. Starting at the ‘Merc’, drive east toward the North Fork of the Flathead River, the western boundary of Glacier National Park. The entrance station is just past the east side of the bridge. The Red Bench Fire spared the ranger’s residence and check-station when it roared through during the summer of 1988. The other historic buildings were not so lucky.² ³

After passing through the check station, veer to the left and then take the first road to the right. The route leading to Bowman Lake is narrow and rough with blind curves and few pullouts. The Park Service prohibits vehicles or vehicle combinations over 21 feet (6.4 m).

Find the picnic area parking lot next to the campground. Signs will help you locate a path leading to the West Lakes Trail.

On the Trail

The West Lakes Trail skirts the south end of Bowman Lake and crosses over Bowman Creek via a substantial footbridge. Within the first 0.5-miles (0.8 km) after the bridge, you will pass a ranger patrol cabin displaying moose antlers over the front porch. I’d like to know the history that this structure has witnessed since it’s construction in 1934. Not far from the cabin, a healthy-looking black bear crossed the trail in front of us.

Built during 1934, this patrol cabin has weathered the years well.

After 0.6-miles (1.0 km) there is a junction with the Quartz Lake Trail. One can go right or left since it’s a loop hike. I prefer the clockwise direction or veering left. From the junction, it’s a climb of 1,200 feet (366 m) over four miles to the top of Cerulean Ridge. Passing over the top, old growth forest gives way to younger lodgepole pine trees. The 36,000-acre Red Bench Fire consumed the forest to the southwest along Quartz Ridge.³ This fire adapted species quickly reclaims the scorched land left in the wake of a fire.

Before the footpath descends far, openings in the trees provide views of all three bodies of water- Quartz Lake, Middle Quartz Lake, and Lower Quartz Lake.

I’m stingy with elevation. I hate to lose that which I’ve gained. But gaining the lake requires descending over 1,000 feet (305 m). At the shoreline of Quartz Lake, the trailhead is 6.1 miles (9.8 km) away with a little more than that remaining in the trip.

The backcountry campground next to the beach is a great place to rest and have a bite to eat. (There are three campsites. Only one is first come first serve.) We sat on the shore listening to the waves roll onto the gravel beach, with the smell of fir trees in the air, and the spectacular Vulture Peak rising into the clouds at the end of the 4-mile (6.4 km) long lake. Our only company was a curious whitetail buck, in velvet. Clouds moved down from the peaks, and a curtain of rain made its way across the water to our new position under large spruce trees. The sound of falling rain and its sweet smell was calming as long as I could shut out thoughts of the miles of wet brush we were about to walk through.

According to Carter Fredenberg, park fisheries biologist, non-native lake trout were first documented in Quartz Lake during 2005.⁴ This species outcompetes the native bull trout, a threatened species, found in the lake. Lake trout also disrupt native ecosystems when they show up. 

Each year since 2009, Fredenberg and his team use a clever strategy to reduce the population of the outsider. They tag lake trout with radio transmitters. These fish lead the team to their fall spawning areas in Quartz Lake, where they deploy gill nets to remove the gathering lake trout. So far, it appears to be successful.⁴

Onward. The trail leaving the campground leads to a footbridge over Quartz Creek in 0.3-miles (0.5 km). At the same time, it changes direction from southeast to southwest. Middle Quartz Lake is small and only about 500 feet (152 m) from Quartz Lake. However, the views of this little gem don’t appear until after the bridge.

The 3.1-mile (5.0 km) walk from Quartz to Lower Quartz is under the canopy of old-growth forest. Glimpses of Quartz Ridge to the west occur every once in a while. You will walk parallel to the lake for a little over a mile before seeing the backcountry campground at the south end. (There are four campsites. Two are reservable. Unlike Quartz Lake, the Park Service allows stock at this site.) You’ll probably need your bug spray if you plan on staying. This site is not on my top ten list. 

Upon leaving the campground, the path turns to the northwest. It crosses Quartz Creek via one of the longest footbridges that I have seen in the park. Over 2.6 miles (4.2 km), your legs will push you up almost 900 feet (274 m) in elevation to the crest of Quartz Ridge. The last leg of the loop drops nearly 1,100 feet (335 m) over 2 miles (3.2 km) before reaching the parking lot.

Numa Ridge Fire Lookout

A place set apart.

If you are looking to escape the summer crowds in Glacier National Park, you may want to consider this hike.

The Numa Ridge Fire Lookout is located in the remote northwest corner of the park above Bowman Lake. Getting there involves driving the outside North Fork Road and then gaining entrance to the park via Polebridge. If you have never experienced this route, you’re in for a treat.

Before heading out, you should know that there is no fuel in Polebridge and no cell service. They are off the grid. Generators and solar panels produce the needed electricity.

The Drive

Option number one starts in Columbia Falls and is pretty straightforward. Drive north on Nucleus Avenue. When you reach the ‘T” intersection, turn right and then motor 35 miles to Polebridge.

A small part of the first 11 miles is paved. However, the section that is not paved can be incredibly dusty and a teeth-rattling enduro – especially during the peak of the rafting season. If you are not in a hurry and you don’t mind a little dust, you’ll see some great scenery.

View into Glacier National Park from the North Fork Road in March

The alternative is to drive from Columbia Falls to West Glacier. Once inside the park, use the Camas Road to access the outside North Fork Road. From there to Polebridge, the road is not as wash-boarded or dusty. Plus, this route gives you eight more miles of terrific scenery.

As any local knows, you cannot venture into this region without first stopping at the historical, 100+-year-old Polebridge Mercantile located just outside the park boundary. The Mercantile is affectionately referred to as ‘The Merc’ in the local vernacular.


There will probably be someone around by 7 AM in the summer. Might I suggest their Huckleberry Bear Claws and a cup of dark roast coffee? If you arrive around dinner time, check out the Northern Lights Saloon and Cafe located next to the Merc. I doubt that you will be disappointed.

From the Merc, drive northeast to the Polebridge Ranger Check Station. It’s another 0.3 miles from there to the Bowman Lake Road. Turn right and then after a bumpy 6 miles on a narrow, winding, dirt road you will enter the Bowman Lake campground and day use area. The parking lot for day use visitors is where you will want to leave your vehicle.

The aftermath of the 1988 Red Bench Fire is pretty obvious as you travel from Polebridge to Bowman. The inferno consumed 38,000 acres, 25 homes, the bridge over the North Fork of the Flathead River, 5 buildings of the Polebridge Ranger Station complex, and took one firefighter’s life. That was the same summer that over one-third of Yellowstone National Park burned.

You might want to entertain the idea of making the Bowman Lake Campground your base of operations for a few days to take advantage of other hikes in the area. The campground has 46 sites, vault toilets, and potable water from May to September. Different walks include Quartz Lake, Lower Quartz Lake, Akokala Lake, and the backcountry campsite at the head of Bowman Lake.

Hitting the Trail

This hike will be 11.2 miles round trip with 2,930 feet of elevation gain. The steepest part is closer to the lookout. The Bowman Lake Trail is at the north end of the main beach. It will lead you to the path that ends at the lookout.

About 1 mile down the footpath, the Numa Ridge Lookout Trail heads off to the north. The sign that says there is no water available on the trail or at the lookout is not kidding. Since the route traverses a south, southeast exposure, it can get warm. So, bring plenty of water.

I would be thoughtless if I didn’t throw in a reminder here to carry bear spray in a quickly accessible location. And, know how to use it. Also, you should know that it can get quite buggy.

Bowman Lake, Glacier National Park
Bowman Lake

Most of the route is cut through a subalpine fir and lodgepole pine forest. But, a little over a mile from the lookout, you will start breaking into an outstanding panorama. Bowman is a quintessential glacial valley lake. You will see its 7-mile-length as if you were in an airplane. To the east is the massive 9,892-foot Rainbow Peak. Its summit is over a mile above the lake surface. To the northeast is the 9,003-foot Numa Peak. As you close in on the lookout, glimpses of the 10,101-foot Kintla Peak to the north are a bonus.

The lookout has been perched on its 6,960-foot site since 1935. It is still in use and happens to be one of the busier posts in the park. We were fortunate to be invited up into the tower for a little “Lookout 101”.

Looking East

Imagine experiencing a thunder and lightning storm or 360-degrees of stars on a clear night from a fire lookout tower. That would be something.


Fly fish? Bowman Lake has cutthroat and bull trout populations (bull trout must be released). However, fishing can be a little slow. If you have some time on your hands, I would suggest the Nork Fork of the Flathead River.

The catch will be mostly cutthroat trout in the 7″ to 10″ class. The fish aren’t huge, but I’ve found that there is plenty of action on dry flies mid-July to early fall. (The knowledgeable and friendly folks at Lary’s Fly and Supply in Columbia Falls will be glad to help you choose flies to match the hatch.)

This day should give you plenty to talk about over a cold beverage and delicious dinner at the Northern Lights.

Life is good!

Kintla Lake to Goat Haunt

An adventure for the books! The 31-mile land segment of our journey started in the northwest corner of Glacier National Park and followed the Boulder Pass Trail to Goat Haunt in the north-central region of the park. From there we motored about 7 miles north on Waterton Lake to the docks in Waterton, Alberta, Canada via the 165 passenger boat the M.V. International built in 1927.

Our journey took us over two mountain passes and along four pristine mountain lakes all the while surrounded by majestic, jaw-dropping scenery. Finally, we crossed the international boundary at the 49th parallel which was negotiated with Great Britain in 1846. It wasn’t planned at the time, but this ended up being part 1 of a 2 part trek from the west side of the park to the east side.


For this backpacking trip, we needed a permit for each of the three specific campgrounds that we intended to use – Upper Kintla Lake, Hole-in-the-Wall, and Lake Janet. Lake Francis was not available to us. If you can get Francis, take it instead of Janet. You will not regret it.

One-half of the sites are available on a walk-in basis the day before or the day of a trip. At this writing, the fee was $7/person/night. Although the Polebridge Ranger Station is a permitting location, I would suggest that you have the permit in hand before driving all the way to Polebridge.

There is also an option to make reservations online up to 7 days before your start date. This opportunity opens March 15 for groups of 1-8 and March 1 for groups of 9-12. There is a $40 reservation fee in addition to the $7 per night for each person. Payment is by credit card or Paypal. If your choices are not available, $30 of your $40 will be refunded.

The tickets for the boat into Canada can be purchased from the Waterton Shoreline Cruise Company. You will need a passport to enter Canada.

It Needs to Start at Polebridge

As any local knows, you cannot venture into this region without first stopping at the Polebridge Mercantile located just outside the park boundary. There will probably be someone around by 7 AM. Might I suggest their Huckleberry Bear Claws and a cup of coffee? If you arrive around dinner time, check out the Northern Lights Saloon and Cafe located next to the Merc. I doubt that you will be disappointed.

By the way, if the Mercantile seems pretty old, it is. Bill Adair built the Merc in 1914. Local folks back then knew it merely as Adair’s. Bill and his wife worked the store and lived in their homestead cabin which is now the Northern Lights Saloon and Cafe. These buildings are now part of the W.L. Adair General Mercantile Historic District which was placed on the National Register of Historic Places in 1986.1

Kintla Lake

Upon leaving Polebridge, we drove eastward and crossed the North Fork of the Flathead River where we entered Glacier National Park. From there we drove north for about 15 miles to reach the Kintla Lake campground. Our kind friend who had volunteered to deliver us to the trailhead cut us loose and headed back to Kalispell. The plan was to get an early start the next day. So, that left a little time to explore.

We met the ranger in charge, Lyle Ruterbories, who was in his mid-nineties and still at it. What a treat it was to talk to him and listen to the stories he had to tell. It turns out that the ranger station at Kintla Lake was built ten years before the area became Glacier National Park. The construction was done by the Butte Oil Company in 1900 after oil seeps had been discovered along Kintla Lake.

Kintla Ranger Station

The oil company hired men to clear a wagon trail from Apgar to the south shore of Kintla Lake. In the autumn of 1902, crews hauled drilling equipment to the foot of the lake. When there was enough ice on the lake, the load was skidded to the drill site. The oil well was the first in Montana. But, it never worked out and was abandoned.

Long before Europeans came to this country, the Kootenai used the land that is now Glacier National Park for thousands of years – back to the Late Pleistocene. In her book, People Before the Park, Sally Thompson explains that the Kootenai used 11 mountain passes to travel east of the continental divide to hunt buffalo. One of those passes was Brown Pass which was accessed either from the Bowman Lake drainage or Boulder Pass side.4 It is interesting to imagine what life was like for those hardy people that regularly used the same general path on which we were about to embark.

Bear Safety

This is grizzly bear habitat. Always carry bear spray where it is immediately available and practice removing the canister from its holster. Be sure that any packaging material has been removed from the safety clip and that you can remove the clip safely and quickly. The time to learn is not when you have a bear encounter. Make plenty of noise to alert bears of your presence. Surprising a bear can ruin your day.

Glacier National Park has a great Bear Safety webpage.

Kintla Lake to Upper Kintla Lake (11.6 miles)

After an early breakfast, we began our hike to Upper Kintla Lake. There is only a gain of about 400 feet in elevation which made for a pretty easy first day. There are sweeping views, at times, of the Boundary Mountains and Long Knife Peak to the north. Close to the head of the lake, is the Kintla Lake backcountry campground. Not too far from the food prep area and sticking out of the gravel shoreline is a piece of equipment left behind by the Butte Oil Company.

The first oil well not far from the shore of Kintla Lake reached a final depth of 1400′, but in the winter of 1902-03, almost the whole works burned. The well never reached a profitable pocket of oil. In 1912, all claims of the Butte Oil Company were declared void. Another company built a derrick near the North Fork River several miles below Kintla Creek, but it stopped drilling in 1903 due to a lack of capital.3

The trail leaves the lake and soon passes a patrol cabin as it gently climbs to some open benches. Watch for signs of the lightning-caused 2003 Wedge Canyon Fire which consumed 52,974 acres during the most significant fire season in Glacier National Park’s history. More than 13% of the park burned during “The Summer of Fire”.

Views to the south-east are dominated by the magnificent Kintla Peak and the glacial horn Kinnerly Peak. The mountain to the east, which resembles the comb on the head of a rooster, is Gardner Point. The Boulder Pass Trail climbs up the south-west flank of that beauty.

Arriving at the backcountry campsite after a full day is always a nice reward. It had been a pretty warm day. The lake beckoned, and we obliged. This day was topped off with a freeze-dried meal, that only seems delicious in the backcountry, a magnificent sunset, and a deep sleep that most often comes to me when I’m in the mountains.

Upper Kintla Lake to Hole in the Wall (9.6 miles)

On the second day, the trail more than made up for the small amount of elevation gain of the first day. Our destination was the Hole-in-the-Wall campground found in the bottom of a glacial cirque of the same name.

Not long after leaving Upper Kintla Lake, we crossed a suspension bridge over Kintla Creek and began our 6.1-mile and 3,070-foot climb to Boulder Pass. We hiked through thimbleberry and cow parsnips (bear candy) some of which was 5 feet tall or more. At times, the lush growth obscured the trail.

We took a little break and grabbed a bite to eat at the Boulder Pass Campground. The talus field below the campground is home to pikas. These cute furry animals are about the size of a large baked potato and are a relative to rabbits. Their physiology makes heat an enemy. There is evidence that climate change has adversely affected some populations in the western United States. Glacier National Park is in the process of determining the health of pika populations within the park. I volunteered to collect data during this trip that will go toward this effort.

This is also an excellent place to see mountain goats which is another species that doesn’t do well with heat. Park biologists are collecting data to determine patterns in the population of this species as well. So, we spent some time counting numbers, determining sex, and age groups within our observation grid.

From Boulder Pass, it is a 3.5-mile and 1,090-foot descent into the Hole-in-the-Wall cirque. The rock that we were walking over, like the rest of the Park, was formed from sediment that was deposited in the ancient Belt Sea which would have been located where eastern Washington and western Idaho are today. Starting about 1.6 billion years ago, the 18,000 feet of sediment, that would become Glacier National Park, was eroded from land that had not yet seen life. The erosion and deposition continued until about 800 million years ago. Then, approximately 150 million years ago, incomprehensible tectonic forces started to shove the enormous rock slab 50 miles eastward. That movement continued until about 60 million years ago.2

It’s cool to see part of the story laid out along this trail by mother nature. The reddish colored rocks with ripple marks or mud cracks look like they were recently made, but are over a billion years old.

Ancient Ripple Marks, Boulder Pass, Glacier National Park

There are also strange circular patterns in the stone. These are fossilized algae called stromatolites. The single-cell photosynthetic microorganisms that made the structures lived in the shallows of the sea much as they do today. These simple organisms played a significant role in forming the oxygen-rich atmosphere that life today depends on.

But wait, there’s more. Over two million years ago, the Earth entered a cooling period. This was the Pleistocene Epoch, and it lasted until about 12,000 years ago. It was the time of the “Great Ice Age” when valley deep glaciers advanced and retreated many times. The beautiful rock that was born in the Belt Sea and shoved eastward was then sculpted by the glaciers into the quintessential horns, aretes, cirques, u-shaped valleys, hanging valleys, and moraines that we take delight in today.

Once you reach the edge of the Hole-in-the-Wall cirque, there are incredible views of Thunderbird Mountain and The Sentinel to the south. Enjoy these views and those of numerous waterfalls as you descend. Keep an eye out on the east side of the cirque for the short spur trail that leads down to the campground.

Thunderbird Mountain from Hole-in-the-Wall, Glacier National Park
Thunderbird Mountain from Hole-in-the-Wall

This magnificent place to spend the night has some ornery mule deer that are pretty persistent when it comes to getting salt. So, don’t leave any hiking poles or sweaty t-shirts lying about the campsite. At Stoney Indian, we actually did have a mule deer doe pick up and carry off a hiking pole. An observant fellow camper went after the deer and recovered it while we were in the meal prep area.

You will no doubt discover this on your own, but I challenge you to find a privy anywhere that has the views of the one at Hole-in-the-Wall. Note that privy implies walls. There are none – just a simple box with a lid placed over a hole.

Hole-in-the-Wall to Lake Janet (6.1 miles)

It was hard to leave Hole-in-the-Wall behind. We started climbing out of the cirque along the southwest flanks of Mount Custer and then Chapman Peak and then descended to the vast subalpine meadows of Brown Pass. Here the Bowman Lake Trail intersects with the Boulder Pass Trail that we had been following for two days. Our path continued to drop in elevation as we headed down into the Olson Creek Valley to the east. It is a beauty. The trail passes close to Thunderbird Pond which provided a great photo op. Looking east above the pond, Mount Cleveland dominates the skyline, and the sharp pinnacles of Citadel Peaks rise in the foreground.

We were not lucky enough to land a camping site at Lake Francis, but the lake is only a short jaunt down a spur trail off of the Boulder Pass Trail. It was well worth the time to visit the lake. From the clean gravel beach, we looked across the water to the towering cliffs of The Sentinel and a waterfall thundering hundreds of feet into the beautiful turquoise water of Francis. The waterfall is fed by the glacial melt of what is left of Dixon Glacier. Words nor pictures can do justice to that scene.

The short 6-mile day ended at Lake Janet. This campground is not on the lake, but the food prep area is near a shaded stream. We found bear tracks along the creek but never did see the bruin. The unusually high cable for hanging food provided entertainment for the impromptu contest to see who could toss their weighted cord over it with the fewest number of tries.

Lake Janet to Goat Haunt (4 miles)

There is a talus field with pika about one mile east of the Lake Janet campground. This was our second site for data collection.

After a short day, we arrived at Goat Haunt which is about 2,000 feet lower than Brown’s Pass. We boarded the M.V. International shortly after arriving at the dock, and then the rain and wind started. Talk about luck! During our 7-mile northward journey on Waterton Lake, the captain slowed as we passed the international boundary. It looked like someone had taken a giant razor to cut the swath through the trees.

After the boat arrived at the docks in Waterton, Canada, it was about another half hour of waiting so that officials could check our passports and backpacks. Then, it was off to a local establishment for a cold brew and burger to wait for our ride back home.

Life is good!
