Can be a boney run. Only consider this range if flows peaked above this and are now holding. Common in summer.
Sorry for the uncreative name. This ledge is typically a mild, almost boring feature with a nice little play wave on river right. However, at higher flows (USGS 3.8' or 1500cfs), the center of this ledge creates a good wave-hole with a decent face and foam-pile. Enders, loops, and cartwheels all possible. Great eddy service on both shoulders.
