About this image

Ius and Tithonium Chasmata are located at the western end of Valles Marineris. Tithonium Chasma is north of Ius Chasma. Valles Marineris is over 4000 kilometers long (2495 miles), almost as wide as the United States. Ius Chasma is almost 840 kilometers long (522 miles), 120 kilometers wide and over 8 kilometers deep. Tithonium Chasma is 803 km (499 miles) long. In comparison, the Grand Canyon in Arizona is about 175 kilometers long (109 miles), 30 kilometers wide, and only 2 kilometers deep. The canyons of Valles Marineris were formed by extensive fracturing and pulling apart of the crust during the uplift of the vast Tharsis plateau. Landslides have enlarged the canyon walls and created deposits on the canyon floor. Weathering of the surface and influx of dust and sand have modified the canyon floor, both creating and modifying layered materials. There are many features that indicate flowing and standing water played a part in the chasma formation. Eroded layered materials on the floor of Tithonium Chasma are visible at the top of the image. Ius Chasma is located in the center of the image.
