This comet-like tail, trending northeast from the volcanic structure, is a relatively radar-bright deposit. The volcano, with a base diameter of 5 kilometers (about 3 miles) is a local topographic high point that has slowed down northeast trending winds enough to cause deposition of this material. The streak is 35 kilometers (about 22 miles) long and 10 kilometers (about 6 miles) wide. The volcano is located at the western end of Parga Chasma at 9.4 degrees south latitude and 247.5 degrees east longitude.
