Sandhills Mammatus

A large field of cumulonimbus mammatus streams east from a supercell unseen to the left, high over the Great Plains vastness of the Nebraska Sandhills. With the vegetatively stabilized dunes impeding any consistently good views beneath the storm's base, we had to be content appreciating with this sight, fantastic in its own right, until the supercell drew closer.
