This is a square block of tuff with a hole drilled/worked through the center. It looks like a mortar that has been used to the point where it wears out, but the bottom of the block also looks deliberately worked, not like it just accidentally was worn through. So I don't know what it is. 1343 g.12.8 cm long; 13.3 cm wide; 7.6 cm high. Found at 2295.865 m; 350 cm from W baulk and 280 from north.
