Testimonial:
Wayne's blog is a hugely valuable daily consolidation of weather, avalanche information, and forecasting, greatly enhanced by his years of experience. No longer having the detailed weather and snow information that I had access to during my 40+year career in the ski industry, I am so glad to be able to go to Wayne's blog as an insightful look at what's going on with current and future weather patterns, as well as valuable guidance on conditions for many family and friends exploring the backcountry.
