C4 Sanctuary Camp

Establish a new camp in C4 The Sanctuary, a large chamber found during the 2016 expedition.

Reached by an easy 24m SRT pitch next to the waterfall at the head of Underground Overdrive.
This will make an excellent base for exploring both the new leads in Underground Hyperdrive, and pushing the downstream leads.
The chamber has an unusually flat limestone floor largely free of boulders. The stream inside the chamber may only flow in wet weather, but water is believed to be available close by from the hammered inlet.
