Venus, False Color of Sacajawea Petera


Magellan image reveals Sacajawea Patera, a large, elongate caldera located in western Ishtar Terra on the smooth plateau of Lakshmi Planum. Sacajawea is a depression approximately miles deep and 74 by 133 miles in diameter; it is elongate in a southwest northeast direction. The depression is bounded by a zone of circumferential curvilinear structures interpreted to be graben and fault scarps. These structures are space to miles apart, are to miles in width and up to 62 miles in length. Extending up to 87 miles in length from the southeast of the patera is a system of linear structures thought to represent a flanking rift zone along which the lateral injection and eruption of magma may have occurred. A shield edifice 7 miles in diameter with a prominent central pit lies along the trend of one of these features. The impact crater Zlata, approximately 4 miles in diameter is located within the zone of graben to the northwest of the patera. Few flow features are observed in association with Sacajawea, possibly due to age and state of degradation of the flows. Color has been added to this image to simulate the appearance of the Venus surface.
