“A beautiful, mellow ascent to the stunning Alaska Basin & Buck Mountain Pass.”— Jason Smith
The trail largely follows the beautiful South Teton Creek into the alpine zone of Alaska Basin. Expect incredible summer wildflowers and be on the lookout for moose and bear.
Though not commonly seen, this is grizzly habitat so be prepared with smart food storage practices & bear spray.
En route to Alaska Basin, the trail climbs steeply at times onto a series of benches. As you get into the Basin, you'll come upon incredible alpine lakes & waterfalls over ancient white granite. The trail is entirely doable, but you'll likely want to adopt a mellow pace to take in the flora, hydrology & geology that makes this area feel so unique.
Above Alaska Basin, you'll encounter the stunning Buck Mountain Pass, with its namesake looming high above you to the northeast. The trail is very well maintained, but expect some stimulating exposure & rocky terrain.
