The comet-like tail trending northeast from this volcanic edifice is a relatively radar-bright deposit.  The volcano, whose basal diameter is 5 kilometers (about 3 miles), is a local topographic high 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, 247.5 degrees east longitude.
