PWL still persistent

CTE4 (SC) down 50cm on SH20 feb. 14 ECTP13 (SP) down 50 cm on SH20 feb. 14 About 5cm of 4F FC sit on top of the Feb 14 SH layer, currently down between 40-60cm below treeline. Still showing surprisingly easy and concerning results on this interface. Was not able to trigger the January layer that was buried down about 1m.
