"Roller Coaster"

Series of Diagonal waves. There are many lines here, the most common are river left (a slide into a wave and then a right turn, punching or surfing one or more additional waves), or center (a straight slide through a series of waves). Some of the best surfing on the river is here. (This rapid begins to be flooded out as the Potomac gage rises over 5' [Point of Rocks gage] and is pretty much flooded out by the Potomac above 5.5' [Point of Rocks gage].)
