"At 9,400ft, in the cirque beneath the ‘Butt Crack Couloir’ on Middle Peak we dug a pit and found:
HS:145 ECTP23 @35cm - this broke cleanly and popped out of the pit. It failed on a layer of buried surface hoar that still retained much of its crystal form.
ECTP26 @55cm - second propagation of a faceted layer on top of a 3cm ice crust. Attached picture is from the first propagation!" Photo: Chris Kussmaul
