• Venusian Volcanic Features

Sinuous rilles emanate from depressions and enlarged fractures south of Ovda Regio. They become progressively narrower and more shallow in the downstream direction. They are typically 1 to 2 kilometers (.6 to 1.2 miles) wide and tens to hundreds of kilometers in length. Channel walls form a distinct boundary between the channel floor and the surrounding terrain. Channel material is similar to that of the surrounding terrain. An impact crater about 12 kilometers (7.5 miles) in diameter has disrupted the eastern channel at center right.
