Snowpit Observations
More detailed information about the snowpack: 

I dug a snow pit on a SW aspect at about 7600 ft. HS was just under 200 cm and I dug down 130 cm. Two moderate failures from compression tests on a storm interface about 25 cm from snow surface. I found a rain/rime crust about 40 cm from snow surface and recent storm snow instabilities were noted above the crust. Below the crust the snow appeared fairly mosit for a few cm. Mid-pack 1F rounding seems to be taking place. Bottom of pit was 67 cm from ground.

Skied a few runs on southernly aspects, snow was heavy and not supportive, punching through the storm snow. Skinning felt like snowshoeing, breaking trail was a little slow going.

I took photos, really nerdy snow photos, but I couldn't upload them. Apparently they were too large
