This is a small pit dug into the EB surface in T20 (surface = locus 104). At 467 cm from the S baulk and 432 cm from the west baulk. We did not finish digging this pit in 2008; it appears to be at least bell-shaped, and filled with few materials. At any rate, we did not succeed in finding the walls of the pit nor its bottom, before lack of time forced us to stop exploring it.
