Located at mile 376 of the Alaska Highway, Erosion Pillar Trail is a short and relatively easy hiking option in Stone Mountain Provincial Park. The trailhead can be found opposite a small round lake approximately 5 kilometers north of Summit Lake Campground. From the parking area adjacent to the highway, the trail leads up a well-groomed pathway until entering a wooded area a few hundred meters in. Follow the trail through the wooded section, which ultimately leads to the base of a prominent 30-foot erosion pillar. From up behind the pillar you can get good views of the Alaska Highway below and the surrounding peaks of Stone Mountain Provincial Park.

Erosion Pillars, or "hoodoos," are created by the erosion of softer material such as clay or glacial til around a more solid form of rock layer which creates a column capped by a protective layer on top. Be cautions when walking around the pillars base because rock and loose material may fall at anytime.

Special Notes: This trail is a perfect length and difficulty for a stretch after a long day driving and will give you a quick glimpse of one of the many natural features just off the Alaska Highway. Many animals also frequent the area, so keep an eye out for stone sheep, caribou, and moose.
