Sacajawea Patera Target Name:   Venus Spacecraft:   Magellan Produced by:   Calvin J. Hamilton Copyright:  © Calvin J.

The depression is enclosed by a zone of concentric troughs that show radar-bright outlines extending from 60 to 130 kilometers (37 to 80 miles) outward from the caldera floor. The floor is covered with smooth mottled plains. The brightest deposits occur around the periphery and near the center of the caldera floor where there is a ponded leveed flow. Linear to sinuous scarps show bright outlines that extend southeast from the eastern margin of the caldera. A small shield measuring 12 kilometers (7.4 miles) in diameter is transected by one of these features. This image is Copyright © by Calvin J. Hamilton.
