Here's a couple words from Luke Short's Desert Crossing. It's an old Western, and the words convey that tone.

• remuda: the herd of saddle horses from which are chosen those to be used for the day by the ranch hands


• malpais: rough country underlain by dark especially basaltic lava. From the Spanish mal pais: "bad country"


• ambulance: a passenger vehicle in the old West


• aparejo: a packsaddle of stuffed leather or canvas
