General Observations

Went split boarding on the north side of Rainbow Ridge. We started a little before noon, and everything was still kind of icy and crusty. Made it to the ridge around 4, and by that time the sun had softened the snow and made for an awesome descent. We dug one pit on the way up. There was a wind slab 1"- 8" thick in places that was moderately reactive. There is also a melt freeze crust depending on the aspect/time of day. Below the top 20 cm, it was all very nicely bonded together. At 20cm, there is a cohesive slab weakly bonded to the well bonded base. It sheared with a shovel test but didn't collapse on the CT.
