Video ID: es020 Title: Autumn Slick-Rock River - Standing Wave & River Pulse Location: Bear River, Maine

The Bear River flows over a section of eroded rock producing a standing wave.

The foreground edge of the rock receives water from peak water levels only, thereby reflecting the pulsing nature of the river.

Afternoon light changes according to cloud cover and to the sun's angle through overhead trees.

Occasional floating leaves and other debris from recent rains herald the approach of winter.
