Pronghorn (antelope) were among the most important big game animals hunted by Nevada's indigenous people. Individuals or small groups of hunters would pursue them during the summer months. In the spring and fall, when the animals congregated into larger herds, individual families would come together for communal pronghorn drives. The drive usually required the services of an antelope shaman who directed activities and was believed to have special powers that let him "charm" the animals into a trap.
