Travel and Terrain Advice
At the Treeline and Below Treeline, conditions are spring with warmer temperatures and rainfall over the past two days. Below Treeline, snowpack is rapidly diminishing, gully holes are forming, and snow bridges are weakening. Be on the lookout for various "terrain traps" in the forest. Also, glide avalanche danger continues at lower elevations. Please stay clear of slopes with glide cracks and move quickly when passing below them.
