Thompson Pass, Alaska is famous for being one of the snowiest locations on the planet, however this location is not always representative of the massively glaciated and colder regions of the Chugach Mountains where snow accumulation is typically far deeper.  Nobody measures the snow pack in this vast rugged wilderness, but H2O Guides has witnessed the annual snow accumulation throughout thousands of square miles of the Chugach surrounding Valdez since the early 90s.  While Thompson Pass is remarkable, the regions where H2O Guides accesses the goods are mind blowing.  The snow get unbelievably deep.  You truly need to see it to believe it.
