 in 1991. According to a surface age map of Mars based on US Geological Survey data, the area around Tugaske is from the Noachian epoch, which places the area's age at 3.8 to 3.5 billion years ago. The elevation around the rim averages about 6700 meters above zero altitude, and the deepest part of the crater floor, in the central pit, measures 5,100 meters above zero altitude. The crater is therefore about 1.6 kilometers deep.
