Avalanche danger has increased during the last couple weeks of April due to stormy weather. Natural avalanches occurring at the high elevations are running to valley bottoms. Portage Valley has seen the majority of this activity which looks to continue into May. Keep in mind that although hiking trails may be melting out, snow covered slopes above could still be threatening them!
