Avalanche Summary

An Avalanche Watch is in effect for the La Garita Mountains, and areas near Slumgullion Pass and the town of Lake City. Very dangerous avalanche conditions develop overnight on Sunday and last through Monday. Travel in avalanche terrain is not recommended during this time period.

Strong winds drifted recent snowfall into thick slabs of snow on north to east-facing slopes at upper elevations. If you trigger an avalanche in the surface snow you could provoke a larger slide that breaks near the ground in weaker snow layers. Look for clues of recent drifting like fresh cornice growth or lens-shaped pillows of snow, and steer clear of areas with a firm snow surface, especially below ridgelines and in open bowls or clearings. You could trigger an avalanche from below or from a distance. You can find safer travel on slopes less than about 30 degrees.
