This is a replica on cowhide of an earlier cowhide painting that represented "Sitting Bull's Dream". If I remember correctly, the original was destroyed and it was recreated by this artist from memory. It is found at the museum at Agate Fossil Beds National Monument. The dream is described at PBS.org this way:

Some time in the early spring of 1876, Sitting Bull climbed to a hilltop, seeking a vision. In his dream, a great dust storm swirled down upon a small white cloud that resembled a Lakota village. Through the whirlwind, Sitting Bull could see soldiers marching. The little cloud was swallowed up for a time, but the storm eventually dissipated and the village emerged unharmed.
