Spring Snow Survival Issues in the High Sierras: Weak Ice, Soft Snow, and Spring Runoff
High Sierra Winter temperatures have been rising for quite a few years now. During mid-Winter this has created a softer, wetter environment. This softer snow has made Winter travel more difficult, and the wetter snow makes for wetter backpackers, which makes it more difficult to retain warmth.
