Many of today's island families are descended from U.S. Army soldiers. Join Park Historian Mike Vouri and learn more about how American Camp's "frontiersmen in blue" played a key role in pioneering Euro-American settlement on San Juan Island. Vouri also will discuss how agricultural operations changed the character of island landscapes, at American Camp. This season's walk may be limited to the park boundary because of the Cattle Point Road construction activities. Stay posted to the park's web site for information.
