Dug pit at 1950m N aspect in the typical gorge 15km area. CTM11 produced a sudden drop/planar result down 100cm, suspected on the early December SH layer. The result seemed to have a lot of 'energy' and the column popped out like a cash register.
As we were packing up, we felt and heard a very large whoomph and settlement.
following this, we adjusted our objective accordingly.
