101 survey practice
Got a lift up the hill in the morning and learnt to use the distoX and topodroid in the bivi cave. Learnt enough to go and do something useful, so headed to 101. Sounds simple. Sadly we didn't completely remember where 101 was (having last visited in 2012) and we had no data in the GPS to help. Spent over an hour wandering around the plateau in caving gear. Headed back to camp to enlist the GPS + an old prospecting map print out. Found the cave easily! Surveyed in splaying and topodroiding (in colour!) as we went. Got past the skylight entrance and down the climb before it got too tight for Olly, and we were cold. Headed out surveying out the skylight entrance as we went.
