This is a little done route that sits just left of Crimson Chrysalis. Start in the large recess just left of Crimson Chrysalis and follow the crack system in the back of the recess to a large gully a few pitches up. Once in the gully, ascend past a huecoed wall with a chockstone above, then step right into another dihedral that leads to the top of the Mushroom.
Location
Start about 100' left of Crimson in an obvious recess. This route lies just right of Tiger Crack, an obvious, arching 5.12 in the recess. From the top, the best option is probably to rappel onto Crimson using 2 ropes.
