Hephaestus Fossae Troughs

I originally thought to name this image "The Big T" but felt that from a composition perspective the image had greater impact when rotated 90° counter-clockwise. The image shows the intersection of two troughs in a region of Mars known as Hephaestus Fossae.
Hephaestus Fossae is centered at 20.9°N latitude, 122.5° E longitude and is roughly 600 kilometers in diameter. The name Hephaestus is one of the classical albedo feature names and fossae refers to the presence of a series of linear depressions found in this area.

The image as shown is a cropped version of the Mars Global Surveyor MOC narrow-angle image R0501304 acquired in May 2003. The image is centered on 22.80°N latitude, 239.56°W longitude. Each pixel covers an area of about 1.5 square meters.
All processing of this image was done using Adobe Photoshop. This includes noise removal, the application of false color, and tonal adjustments.
