Route & General Observations

Toured the Seattle Ridge up-track to 2500′. We did rescue drills and looked at surface conditions. Also got a good look again towards Todd’s bowl and Tincan in our inventory of paths that have slid this season. Heather’s pit Wednesday showed a very weak snow on a melt-freeze crust in a Cornbiscuit path that had slid. We are concerned about paths that have slid being repeat offenders with a new snow load.
