Name origin
"'Avalanche Mountain' seemed a good name since (1) avalanches make 'snow thunder' or 'rock thunder' and (2) the Source Lake basin, just south, is famous for this treacherous phenomenon -- of both the snow and rock varieties." - John Roper in the March 1995 issue of Pack & Paddle.The Seattle Mountaineers call this peak "Rock Thunder". This name was given by Dave Beedon, a former Seattle Mountaineers scramble leader.
