Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Government peak 2500' @ 11:53am, few clouds, calm wind, 24F degrees.
Weather was great throughout the entire day and at times felt like spring skiing.

Snow surface

A variety of different surface conditions were observed during our tour. On steep southern aspects a notable 3-4cm sun crust could be felt on the ascent. Wind effected snow was observed above 2300' near ridges. Old sastrugi was abundant and old rime crusts are exposed. On northern aspects dry low density snow could be found. On the descent back to the parking lot, snow surfaces began to warm up. With dry snow becoming moist on steep south facing slopes.

Snowpack

We dug on a southeast facing aspect and found poor structure, moderate strength and low propagation propensity. The poor structure involves 4-5mm rime crust sits 40cm below the surface. On top of this crust sits 1mm facets and a 40cm 4F-1F slab. The bottom of the snowpack has 35cm of facets and depth hoar mixed together.
