8/9/20

From Mike. Stuart capped most of the boulders in the end chamber, despite forgetting any spare drill batteries, whilst Dave, Fran & I lifted the 2nd grill & removed most of the mud from underneath it (18 buckets worth) in stages. Stu then put most of the bits of rock up on the right hand shelf before running out of oxygen & exiting. Then Dave & I headed back down for 5 minutes whilst the others got changed - Dave dug out the remaining wall between the 2 puddles & I lifted the rest of the rock onto the shelf, except 1 large block (that is lose) & any that I couldn't see (pool was crystal clear when we arrived, & a couple of inches lower than last week). Still some mud (grill is up on the side) & the rocks to remove next time.
