Molalla Deep

October TBA Molalla Deep (If we get permission from
Trip leaders: Jerry Zimmer and Mike Loomis
This rare and unusual cave is said to be a block creep or
slump cave. According to Mike Loomis (1988 cave trip), the
cave drops down mud hardened walls to a water source that
appears to have no bottom. The passage way narrows to a V
shaped passage making progress difficult even though the
cave appears to continue on. In short, we need to get back
into this cave and further explore it!

Gear list: helmet, 3 light sources, cave pack, gloves,
vertical gear. Wet suit and or a small raft would be useful
