General Comments

Noticed most of the Wellsville drainages slid during yesterdays storm. Looking at the slides through the spotting scope, it appeared to be the new snow only. Most of the slides were fairly small (100 feet wide) and only ran several hundred feet. The most significant was at the top end of South Shumway canyon. It appered to be 300-500 feet wide and ran about 1000 feet. I took several pictures but none of them turned out good enough to send in.
