Uranius Tholus and Rahe Crater

Today's VIS image shows the northern flank of Ceraunius Tholus (bottom of image), Rahe Crater (center of image), and a full cross section of Uranius Tholus (top of image). Ceraunius Tholus is 128 km (79 miles) across and 8,500 meters (27,887 feet) high, close to the height of Mount Everest (29,031 feet). The slopes are relatively steep, and there are several very large channels dissecting the flanks of the tholus. One major channel flows into Rahe Crater, which may have created a lake. Uranius Tholus is 61km (38 miles) wide, and 4290 meters (14,075 ft) tall. These tholi are some of the smallest volcanoes in the Tharsis region. Rahe Crater formed from an oblique impact, causing its elongated form. Rahe Crater is 34km (21km) in diameter.
