This heavy canvas poncho was cleverly made to also function as a bag, ground sheet, or makeshift shelter. When worn as a garment, its voluminous shape and rain-resistant fabric keep the wearer dry. When it is laid flat into one large rectangle, the collar covers the neck opening. Buttons and buttonholes along the edges can attach to each other in various configurations and anchor laces or rope. It belonged to Dr. Belle A. Stevens, a University of Washington educated zoologist who served as a leading authority on hermit crabs. She wore the poncho while boating in the San Juan Islands, possibly while doing research.
