Climbed to 4250’ and dug a pit in some trees to check snowpack. Snow depth around 130cm. Found the deep depth hoar at around 25 cm. Extended column test and it broke clean at the 25cm as a slab after 10 medium and 7 hard hits. I stuck to the trees and did not witness any natural avalanches or experience any whomping or cracking. Biggest concern ended up being tree wells.
