Observation: Summit
Location: Colorado peak
Planned to ski in Turnagain Pass but the lack of plowing/parking sent us out to the summit lake area were we could also barely park. We went up the eastern slopes of Colorado peak to 2,375′. The most dangerous part of the day was traffic congestion at many parking lots where people were pulled over trying to park, lots of cars and semi-trucks flying by…. people and parked cars near the white line. Sketchy.
Obvious signs of instability
