Not what I expected

Dug a test pit CTM 8 down 30cm RP - very resistant and breaking over 10cm of depth CTH 4 down 40cm RP - very resistant and breaking over 10cm of depth DTH 3 down 105 SP on dec 4 crust Evidence of old tracks in the middle. Figured we were OK to drop in and climb out. Dropped in and climbed out with no problems. Dropped in a second time about 3m over from center track, did a downhill carve and slope broke away.
