Humpback Mountain
This scramble varies in distance, elevation gain and difficulty according to season and snow conditions. Without snow it is easy, mostly on way trail, 2,600 feet of elevation gain and 5.2 mile round trip. The summit block is large talus with views of the I-90 corridor to the east.
ASCENT ROUTE
The standard route follows the northwest ridge, with access point determined by how far one can drive up Hansen Creek on Forest Road 5510 (which is determined by the snow level). Highest starting point is at approximately 2,900 ft. Note that this trip summary begins from the lower starting point. Walk the gated road to the ridge line, catching a boot track slanting back to the right. The "trail" follows the ridge, eventually reaching taller trees. The final narrow summit block/large talus often requires ice ax use with snow. True summit is at the south end, reached by passage on the west side of the talus.
