Why is it called the Pinto Wye Arrastra? I've wondered about that and had a theory, so I decided to see if I could find any facts to back it up. And as things turned out, my suspicions were correct. As it wasn't the only arrastra in the park, it couldn't just be called "the arrastra." That would cause uncertainty and vague feelings of unrest. But as it was located about three-quarters of a mile northwest of a "Y" in the main park road (the spot where Pinto Basin Road meets Park Blvd.), someone somewhere sometime called it the Pinto Wye Arrastra and the name stuck.
