More detailed information about the snowpack: 

It wasn't terribly warm before noon but started to warm up in the sun in the afternoon. We noticed mild melting occuring on only the most sun exposed slopes. Winds were calm with just a few cirrus clouds drifting by.

The snow around Leavitt is heavily wind affected, variable density sasturgi covers nearly the entire area, minus zones that are entirely wind scoured. The lake still looks a bit suspect to cross on a sled.

We chose to dig a pit on a NW aspect. Below a thin wind crust we found a layer of near surface facets and a rapid change in temps. Lower in the pack, roughly 25cm from the ground, was a well defined melt/freeze or rain crust that was sandwiched between facet layers. The facets below the crust were most developed and beginning to show signs of striations. A CT test produced results of CT11 BRK at the crust but no results were produced from 2 ECT's. A  PST just below the crust propagated to the end at 40cm. This crust layer and surrounding facets will be one to monitor.

We observed an old avalanche crown in the bowl above Leavitt Lake, HS-U-R2-D2.
