Martis is the name given by scientists to the group of Native Americans who lived in Northern California on both the eastern and western sides of the Sierra Nevada.

[6] They shared certain traits which included making stone tools from basalt, using pestles and mortars, and hunting with atlatls and spears.

[8] Martis people processed seeds and hunted big game, such as bighorn sheep, pronghorn antelope, deer, bison, and elk.

[9] Archaeologist M.J. Moratto states that the Martis were not related to the Washoe, but may have been linked with the Maidu.

[1] The Meadow Lake Petroglyphs, attributed to the Martis, are a national historical landmark.
