Did Lake Manly overflow at ash hill?

Description :
The observations discussed in this paper concern the maximum area of Lake Manly, the pluvial lake that occupied Death Valley, and in particular the question of whether it ever became large enough to overflow at a place called Ash Hill. Despite its size, new field observations suggest that the channel was actually eroded by local runoff. Water from several tributaries collects into a single channel at this point, and the resulting discharge is apparently sufficient to cause retreat of a knickpoint from the downstream edge of the basalt flow into which the channel is cut.
