Red Flag Comments:

Was scared to get on anything above 25 degrees. Widespread clues to unstable snow conditions. Checked out the slide we triggered yesterday to see how the new snow was bonding to the bed surface...12-18" already reloaded with poor bonding and shooting cracks...Fairly concerned these things have a high likely hood of repeating...
