This is the Kokanee glacier. You have to drive up a logging road near the Kokanee Creek campground to access the trailhead. This is what's known as the Keyhole, a hike that veers off the main trail to the lake and goes up. You have to scramble up large boulders and some steep scree so it's not an easy hike. If I remember right it took about 3 hours. #hiking
