An efficient start for a deep rigging trip was marred by neglecting to bring any drill bits. Fortunately this was discovered whilst rigging a traverse line in Goody goody. Usefully, Becka discovered a high level continuation in Northward direction while taking a pee at Naughty naughty junction. So we made the best of the situation and gave Chris S some note-taking experience by tandem surveying with Becka also on notes. Surprisingly crystalline formations - aragonite? - growing from popcorn. Stopped at dig which gave Chris S an opportunity to warm up with some thrashing about.
