On Tuesday, Feb 6, we extended the Jump 29 line by another ~600ft, so that East shallow line is now about 1,500 ft long running in depths betweem 25 ft and 45 ft (6 and 13 meters).
While my buddy was tying off the jump spool to go East, I took snaps of the directional marker pointing to Jump 30 (West Shallow) line placed in there by other team members to help the Jump 30 team with their navigation.
Throughout the expedition, East shallow line consistently had the best visibility. Due to recent snow/ rain / snow sequence and increased runoff that affected the whole system, the visibility on the first 800 ft on the East line declined . Visibility then improved dramatically further East as we were adding new line, allowing us to stay in the same tunnel. Earlier, putting down the first 1,000 ft of line , the team encountered column numbers 11, 12, 13, 15. We saw 19, 20, 21 and 22 when adding the 600 ft of line on Tuesday.
The find of the day for me, along with the column numbers was a little blue teapot sitting in the red rubble.
