Ophir Swamp

Complex upper snowpack. Two separate near-surface faceting processes happening in the upper 40cm. Radiation Recrystallization at the surface with a few hours of off angle sun in the morning and Melt-Layer Recrystallization at 171cm from the wet old snow surface prior to storm on 3/13. Pack is cooling so frozen crust at 171cm will take a larger load and need a bigger thump to activate unless we get another strom warm up.
