A tour up Green Butte Ridge saw a mixed bag of conditions. Gaining the ridge is a challenge coming out of Bunny Flat. Expect a thin snow pack, scoured snow surfaces, rocks, and manzanita. On reaching 7400', travel becomes much easier. In wind sheltered areas, the height of new snow (HN) was 2-3 inches (5 - 8 cm). New snow was dry and unbonded to the old snow. Many small isolated wind drifts were encountered along the way where the strong winds had not blown the snow off the ridge. These drifts varied from 6 - 24 in (15 - 61 cm). Drifts typically consisted of a 4F- soft wind slab 2 - 8 in (5 - 20 cm) sitting atop a F hardness layer of fragmented precipitation particles (DF). These soft slabs were stubborn to trigger and little to no propagation was observed. A quick column test showed no concerning reactivity (ECT18N RP). No large slabs were encountered. The ski below Sun Bowl to Everitt was dreamy, though a few rocks and obstacles lurk beneath the new snow.
