In suburban Boston, Massachusetts, in the Pine Ridge Cemetery for Small Animals in Dedham, is a large roughly shaped pinkish stone with the carved inscription: "IGLOO. He was more than a friend." Igloo was, of course, the faithful canine companion of Richard Byrd, and the stone marks his grave.
The fox terrier travelled everywhere with Byrd and was an expeditionary veteran of both the Arctic and Antarctic. He was even the subject of a biography: Igloo by Jane Brevoort Walden (G. P. Putnam's, 1931).
