Stop 7: Erosional chaos


This photo was taken on a hot August day, when the stream was reduced to a barely audible trickle, lost among this chaotic jumble of boulders.  It is hard to imagine how this same gently gurgling brook can transport boulders weighing hundreds, if not thousands, of pounds during spring and summer floods.   In the narrow confines of Stebbins Gulch, stream levels can rise from a few inches to several feet within hours.  High water makes it impossible and extremely dangerous to try to negotiate what, in effect, becomes a whitewater torrent.
