Any route that starts and ends from White River Campground and reaches the high point of Steamboat Prow is acceptable for this FKT. It is popular in late spring with climbers and skiers, with stunning views over the northeast side of Mount Rainier. The route starts by hiking up the Glacier Basin trail to Glacier Basin Camp. Parts of the trail may be covered in snow. From Glacier Basin Camp, you can usually ascend an established bootpack to Steamboat Prow. Alternately, you can climb the ridge on climber's left to Mount Ruth and traverse across and up along the ridgeline to the prow.

This mountain towers over the extremely popular cascade pass trailhead/parking lot in north cascade national park. It has a long history going back to the very well known Ptarmigan Traverse. It has a strong reputation with PNW climbers/mountaineers for its unique tree climbing/vertical bushwhacking and its sheer size and complexity.
