Another such burning question, in regard to which the Internet has utterly failed me, was recently satisfied by my uncle, who is very, very fluent in Spanish. The Tusas Mountains, the arm of the San Juans which depends southwards into New Mexico near Chama, are in English the Gopher Mountains. I love these instances in which the Web and its gibbering digital hordes are laid waste and pillaged by genuine erudition.

Thanks Chas, and leave them snakes alone!
