Kennecott used to be a small copper mining town in the early 1900s and Bonanza Mine
is currently the most accessible mine, requiring a lengthy, but straightforward, day run. The trail begins near the beginning of the Root Glacier Trail
close to the end of Kennecott Road. Follow the switchbacks through the trees up to the tundra, where the views really open up. The Bonanza bowl is very picturesque with patches of snow, a stream and small waterfalls, and turning around, you see Root Glacier
and the Chugach Mountains.
Continuing through the bowl, remnants of mining operations are ever-present and the trail culminates at the mine bunkhouse ruins. Here, you can run around and observe the historic artifacts, and if you are ambitious enough, you can continue up to Bonanza Peak
. The route to the summit is described in the Bonanza Peak
The trail has an intermediate / difficult rating due to its grade and patches of snow along the trail.
Bears are known to be present on and around the trail.
