Dug a profile at the top of Trash Chutes. NNW aspect at Treeline. 20 degree incline. Extended Column Test failed in the moderate range, and propagated across the whole block. ECTP 17 down 65cm on Jan 25 Surface Hoar, size 6mm. Compression Test revealed CTM 11 (with Sudden Collapse fracture character), also down 65cm on 6mm Surface Hoar. We experienced a decent whumph at the profile site while prepping to dig.
