Green Butte Ridge General Conditions
A crack in the snow was further investigated on a tour up Green Butte ridge today. The crack ran approximately 200 feet perpendicular to fall line on top of the south facing ridge rapping towards west and north facing aspect into small. It was .5-1 inch (2-5 cm) wide. Upon further investigation to the west found the crack branched out into a small cornice forming on the ridgeline. This crack likely started as a slab on north and west facing aspects of Green Butte forming into a small cornice feature along the ridge. The crack towards the lower angle, south facing aspect has self-arrested on lower angle terrain on top of the ridge. The freeze and thaw pattern of our weather has further opened this crack.
