(Alaska)
Wood-Tikchik State Park is a state park in the U.S. state of Alaska north of Dillingham. Over 1,600,000 acres (650,000 ha) (6,500 km2) in area—about the size of the state of Delaware—, comprising more than half of all state park land in Alaska and 15% of the total state park land in the country. Despite being the largest state park in the nation, the park had no staff whatsoever for its first five years, and even now at times only a single ranger is in charge of patrolling the entire park, usually by aircraft.
