The Talus Trail starts from the XC ski 'stadium' area, just north of the paved parking lot at Pincushion Mountain.
Follow the singletrack east, away from the open field, and off into the woods.
Initially, you'll be primarily climbing (overall), for a short distance, before the rolling singletrack crosses a XC ski trail where it flattens out before starting a descent. The trail eventually turns into a consistent but relatively gentle descent as you make your way down towards the (unnamed?) creek crossing.
The track is primarily made of dirt in this section - other trails in the Pincushion trail system have much more bedrock.
