Here is another Blue Creek Story -

Dec 21 (can't remember what year) we are on Anderson Bar on a ****ty rainy day, when one of the Army decides to climb the hill. He makes it pretty high up before giving up the quest. This cut a parabolic rift into the muck laying on the hillside. We didn't think much of it until the next day, when that entire patch cut loose. We were Knee deep in the river when it hit and it drew the water out from under our feet and threw back a wave twice that high. I believe that that climb is what led to the catastrophic slide on Super Bowl Sunday (The one that killed one and entirely blocked the Cowlitz for a couple of minutes)
