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.
