>I toured Green Mountain (9,800+ft) with Scott and Morris yesterday. We rode the snowmobile to the trailhead of North Leigh Creek (7,000ft) and skinned up the north end of the west face. The new snow that fell Monday and Tuesday averaged about 8 inches. We had bluebird skies and the temps were in the upper teens and low 20’s with the occasional light breeze.
We dug two pits, one at 9,800ft and another at around 9,600. The second pit was on a slope of 25 degrees. Snow depth was 80cm. We performed a Rutshblock test on the second pit. The slope angle was approx. 25 degrees (at the low end of slope concern) and it broke free on 4 and slide at 5 which indicates a yellow light. If you’re not familiar with this read more at: http://www.avalanche.org/~nac/slideguide/new_slides/rutschblock.html
The alarming thing with this is that a slope angle of 25 degrees is at the bottom end of suspect angles. On our skin up we did not experience any settling, whoomping, or cracking. We identified one avalanche which broke out a slab below a cliff band on a peak to our east. This was on a west aspect and could have been above 10,000ft. Last but not least is the noticeable surface hoar due to the cold temps the last few days.
