Climb up the corner towards the tree, then head right through the tunnel. Tip-toe across the top of the flake towards a handcrack that leads up to a hemlock tree. The last move can be reachy. Belay atop the tree. From there, head up the hand/fist crack, past a small cave, up two finger cracks, and to a large belay ledge with a pine tree. Pitch 3 goes up the (sometimes dirty) crack to the right of the tree towards an undercling flake. Climb above the flake and head RIGHT up some bolts (left leads to more challenging, run-out slab).
Walk across the ledge (past a 5.11 with a "culturally modified cedar" at the start) to the west of the giant roof on the Solarium wall. Where the ledge meets the roof, there is a single bolt to protect your belayer. Head up the corner towards the tree.
Rack to 4-5".
