161 - Fuzzy Logic
Carried rope & Hammer drill to Top of 1st pitch. Drilled extra pitch head bolt for Y-hang. Descended pitch while Dan rerigged top of pitch. Top of 2nd pitch - Drilled 2 pitchhead spits for Y-hang by hanging off a flake with sling to take rope out of water. Stepped on original natural flake at top of pitch and it disappeared beneath me with much booming. Descended pitch and was able to thread a deviation sling thru a tiny flake to deviate rope out of water and descended to ledge. Started to drill a rebelay spit just below the ledge when the drill battery ran out of juice so exited cave with battery to recharge as we lacked any other form of spit drill.
