Gable Mountain is a truly impressive hulk of rock. The precarious summit, which has a slight overhang with severe exposure on the south side, is a bit reminiscent of the curled peak where The Grinch Who Stole Christmas calls home. Along the jagged ridge top, several other impressive high points reach to the sky. Expansive boulder fields litter multiple flanks of the mountain, constant reminders that the terrain in this stretch of northern Montana is forever changing. The mountain is a geologic wonder, with numerous rock formations, each donning a distinct color and texture, scattered about the crumbling slopes. To view Gable Mountain is to experience the wonders of Glacier National Park's Lewis Range in all its splendor. 

To the east, famed Chief Mountain rises from the saddle at Gable Pass. Although it is over 100 feet taller, Gable Mountain sees essentially no traffic in comparison to its culturally and aesthetically prominent neighbor. Chief holds a special place in the Blackfeet tradition, and with relatively easy and well-documented access from several directions, makes for a straightforward, albeit long, day climb for most parties. Gable is an entirely different story. Access is much more difficult, due to formidable cliffs and rotten rock that encircle the mountain. The easiest route is from beautiful Slide Lake , and it involves a little bit of everything: creek crossings, talus fields, massive waterfalls, extensive bushwhacking, a maze of game trails, and mixed class II/III climbing on loose rock. Reaching the top is not easy, but those who do will be rewarded with an incredible summit view that is likely experienced by only a handful of folks every year.

Getting There

Gable Mountain
Gable Mountain from Lee Ridge. The sharp summit is visible at center.
Gable Mountain is located in the extreme northeast corner of Glacier National Park, just a few air miles south of the Canadian border. Although it is close to the park boundary, the route up is very long and is best done as a multi-day outing. The wonderful backcountry site at Slide Lake makes for the perfect place to set up base camp. There are two maintained trails leading to Slide Lake. A permit is required for all backcountry camping in Glacier National Park; see the "Where to Stay" section for more information.

1) Lee Ridge Trail - Trailhead is located approximately 1/2 mile south of the international border crossing on Chief Mountain International Highway (MT 17). Look closely for an orange blaze and a brown NPS sign denoting the start. There is no parking at the trailhead, but there are a few pullouts within 1/2 mile of the trailhead with enough space for a car or two. Otherwise, one can utilize the very large parking area at Chief Mountain Customs. The trail spends the first three miles in a lush old growth forest before emerging on top of the windswept open slopes of spectacular Lee Ridge. Follow cairns and the occasional sign over Gable Pass, where a steep trail leads down to Slide Lake. This is an absolutely incredible hike with sweeping views and solitude.  It's approximately 8.5 miles from the Lee Ridge Trailhead to Slide Lake Campground. 2,200 feet of elevation is gained over 6+ miles to Gable Pass, with 1,400 feet of elevation lost over 2.5 miles to Slide Lake.

2) Blackfeet Reservation Road - A short trail leads 1.4 miles from the park boundary adjacent to the Blackfeet Indian Reservation to Slide Lake. The trail passes the historic Slide Lake-Otatso Creek Patrol Cabin along the way. The gravel reservation road is reported to be horribly washed out and challenging for even four-wheel drive high clearance automobiles. I have no personal experience with this road; please inquire locally at the Many Glacier Ranger Station for more information. The following information is taking directly from the NPS's trail status report page for Glacier:

NOTE - A $10.00 Blackfeet Tribal Conservation Permit is required by each person(regardless of age) to cross reservation land. All hikers or riders using this road to access Slide Lake cross the reservation.

VEHICLES NOT RECOMMENDED. The normal entry to the Slide Lake area is by way of an unmarked road across Blackfeet Indian Nation land. Road into boundary is very muddy, rutted and rocky, and there is significant damage due to flooding. Also, the road is used heavily by cattle.

The road is not marked by a sign and is reached by leaving US Hwy #89 at Chief Mtn Jct. and going 4.3 miles on the Chief Mtn.Hwy (Route #17). Look for a dirt road heading west/southwest and skirting just south of Chief Mtn. If hikers are unsure about locating the road, tell them to look for Chief Mtn. overlook, which is a signed pullout 0.3 miles northwest of the Slide Lake road at a point 4.5 mi. from Chief Mtn. Jct. This overlook is known locally as Crusher Hill. The distance from the Chief Mtn. Highway (paved) going west on the Slide Lake Road (dirt road) to the trailhead at the Park Boundary is approximately 6.0 miles. We do not recommend driving this road as it is extremely rutted and in poor condition. There is one major fork in the road a couple miles in, the left fork that leads down towards Otatso Creek is the way to Slide.


* I should note that I do not have many photos that help illustrate the route. Our summit day was very long and arduous, and my camera stayed in the pack as we spent the better part of the day bushwhacking, fording, post holing and scrambling on loose rock. I will attempt to make up for the lack of photos with a detailed route description and some topographic maps. Also, even with a base camp at Slide Lake, climbing Gable Mountain is a very long outing. Our group took about 11 hours round-trip from our backcountry campsite. Plan for an early start! 

Follow a well-worn trail along the north shore of Slide Lake all the way to the inlet of Otatso Creek. The creek is shallow and mellow here (it was no more than 2 feet deep in June 2012), so look for an easy place to cross to the opposite bank. Follow the creek west until a broad meadow is encountered. An old mining cabin (marked "Runis" on the Nat Geo Many Glacier topo map) located in the middle of the meadow is definitely worth a stop. From my research, it appears that the area around Otatso Creek was mined extensively by a man named John Van Pelt sometime in the late 1800's/early 1900's (1). Until recently, an open mine shaft could be found less than a mile west of the ruins just north of the unnamed creek that drains from Seward Mountain. However, the NPS opted to close the shaft in 2010; please see the references section at the bottom of this page for a link that outlines the closure project. Pretty interesting stuff!

A massive waterfall on Otatso Creek is clearly visible just to the southwest of the cabin. The route detours up and around the falls to the south. Simply follow the meadow toward the falls, and look for an easy way to gain a few hundred feet of elevation to the south. A short bushwhack will almost certainly be required, but it should not last long and soon a large talus slope will provide easy access above the falls. In June 2012, there was a large, steep snowfield that our group needed to traverse as we detoured around the falls. Please note that at the very least, an ice axe should be utilized here in the event of a fall. After the falls have been negotiated, one simply needs to traverse above Otatso Creek across talus fields and grassy slopes. Ultimately, Otatso Creek needs to be crossed, and there are multiple places to do so. Descend to the creek and try to identify a place where a safe crossing can be made. Shoes and socks will almost certainly have to be removed for what should be a very brief ford.

approaching Gable Mountain
The summit is just left of center atop the rock face with two distinct light bands. Aim for the pointy sub-summit below and to the left. The remainder of the route becomes obvious from there.
Follow the creek uphill to the west for less than a mile, using game trails to make the traveling easier. A few small tarns are encountered, and eventually a prominent cascade is reached on Otatso Creek. It's best to scramble up the terrain just east of the falls. Route finding options are plentiful, but the goal is to continue heading uphill until above tree line around 7,000 feet in elevation. The route continues up loose talus and scree towards a sub-summit atop a ridge that extends south/southeast from Gable Mountain's summit. Once the top of the ridge is gained, the rest of the route up the south face comes into full view. Multiple route options exist, and although a few class III moves are required, the route finding is generally intuitive from this point on. Follow the ridge (the drop off towards the huge boulder field to the east is quite impressive!) until the terrain becomes too steep, then make an ascending traverse towards the ridge top to the northwest. Once the main summit ridge is gained, it's less than 30 minutes to the summit proper. Simply retrace your route for a safe descent. 

Sean Doyle (ManyGlacierMountaineer), a trusted hiking companion of mine, stayed well north of Otatso Creek on his descent in July 2010. He reports that his group traversed the massive boulder field that spills south of Gable's summit, and from there an "elk super highway" provided easy access back to the meadows west of Slide Lake. I have no experience with this route, but it would be much shorter than the route on the south side of Otatso Creek.

Summit Views

Perhaps my favorite aspect of the grand view from the top of Gable Mountain is down into the wild Otatso Lake area immediately to the south. A series of serene tarns are perched on a broad bench beneath a sheer cliff face, making for a spectacular scene. The slightly overhanging summit and gigantic boulder field directly beneath the summit give one an up-close-and-personal look at how the terrain of Glacier National Park, although primarily comprised of stone, is forever changing. To the north, the wonderful Belly River snakes its way towards Alberta, Canada. Mount Merritt and Mount Cleveland are visible to the west, and on a clear day the Sweet Grass Hills, anomalies rising high above the Great Plains, are visible nearly 100 miles to the east. 

When to Climb

Due to extreme winters along the Continental Divide, problematic snow can linger on trails and mountain slopes well into July and August. Hence, the climbing season in Glacier is rather short, and often begins in June and can last into October, weather permitting. However, some lower peaks and southern facing slopes can be safely attempted much earlier in the season. Your best bet is to inquire locally about snowpack and weather conditions. I use the NOAA for detailed weather forecasts for the greater Glacier area; check out the website here.

On June 16, 2012, ice axes were essential items. Steep snow can linger at Gable Pass well into July; check the NPS trail status report page or inquire locally at St. Mary or Many Glacier for conditions. The route to Gable Mountain also involves a steep snow crossing while detouring around the large waterfall on Otatso Creek. Definitely not a spot where you would want to take a tumble, especially when considering the remoteness of the area. Help is a LONG ways away back in this neck of the woods. Lots of snow was encountered in the forest along Otatso Creek as we approached the mountain, but it was very hard packed and actually made the bushwhacking quite a bit easier.

Where to Stay

Lower Slide Lake
Near the Slide Lake backcountry campsite
I would highly recommend staying at the wonderful backcountry campsite located at Slide Lake. A permit is required for all backcountry camping in Glacier National Park. The nearest permit-issuing ranger stations are at Many Glacier and St. Mary, so inquire locally regarding availability. As of 2012, cost is $5 per person per night. I doubt that Slide Lake fills very often, so it is likely not worth the additional $30 to reserve a backcountry site in advance. Visit this page for more information on backcountry camping in the park. 

Car camping can be found in the park at Many Glacier and St. Mary, and there are a variety of campgrounds, cabins, and motels on the Blackfeet Reservation off US-89 around St. Mary and Babb. 

Red Tape, Wildlife, etc.

A fee is required for all persons entering Glacier National Park. As of 2012, single vehicle rates were $25 for a seven day pass, or $35 for an annual park pass. A full explanation of the entrance fees can be found here

Glacier is subject to extreme winter weather conditions, and as such, much of the park is virtually innaccessible for the majority of the year. The Going-to-the-Sun Road is completely only open from mid-June to mid-September, and as such, many of the civilzed areas of the park (including the historic lodges and many of the campgrounds) operate for a short window as well. All of the services in Many Glacier are closed by the end of September, and after it starts snowing, the road is not plowed until May, so plan your trip accordingly.

The ancient rock in Glacier National Park tends to be quite crumbly and rotten; as such, a special rock grading system has been developed to help climber's safely approach peaks throughout the park. Refer to the Glacier Mountaineering Society's website for detailed information. 

The park is home to lots of potentially dangerous wildlife, including moose, black bear, grizzly bear, and mountain lions. Hike loud, carry bear deterrant spray (and know how to use it!), and let someone know your intended route before heading out into the park. 

Pick up a copy of J. Gordon Edwards classic A Climber's Guide to Glacier National Park. It's an absolute must for anyone who wants to safely venture to one of the park's many accessible mountain summits. His route information is often invaluable, and it will introduce you to many exciting climbs and off-trail hikes scattered all throughout the park.

Visit the FANTASTIC Glacier National Park page, a labor of love by late Summitpost member sainitgrizzly (R.I.P.), or the NPS page for more detailed information.


Kudos to Chris Dickson and Summitpost member Brooks McClintock (brooksmcclintock) for an amazing two days spent exploring the wonderful Slide Lake/Gable Mountain area. Thanks to Sean Doyle for providing me a few photos and route information that helped round out the page.
