A volcano on the plains between Artemis Chasma and Imdr Regio displays a sheet of thick radar-bright flows and broad flow lobes. This type of flow has been name "festoon" and only three have been found on Venus [Head et al., 1992]. The lobes and flows show prominent transverse ridges that have an average spacing of about 750 meters (2,460 feet). The flow features are associated with a complex domical structure about 100 kilometers (62 miles) across and 1 kilometer (.6 miles) in relief. They are surrounded at a lower elevation by plains surfaces that expose radar-bright volcanic deposits [Moore et al., 1992]. These materials extend some 360 to 400 kilometers (220 to 250 miles) from the volcano. They appear to overlie the radar-dark, lowland plains that dominate this region of the surface.
