Snow pit today was west of Silver Lake in the snowy range at 10,404 feet. We were on a south aspect with a pit depth of 117 cm on a 22 degree slope. We performed a couple tests to see if we could eliminate the persistent week layer from our earlier February 10 layer and did get some reactions. Our extended column test results were ECTP22 and our propagation saw test results were PST 60/100 END @79cm.
