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 20.9N 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.
