Known for the chorus of tree frogs in the area, Frog Holler is a local Vashon Island neighborhood along Wax Orchard Road just north of Camp Sealth. The largest portion of Frog Holler Forest is one-half mile south of Bates Road on the east side of Wax Orchard Road. The previous owners had enrolled the forest in the American Tree Farm system and allowed local neighbors to use the network of trails on site. The site has a 5-acre pasture that had been grazed by sheep, goats and horses over the years. A 39 acre parcel west of the road was added to the site in 2020. Frog Holler Forest is the largest public forest on the south end of Vashon Island.
- Salt Creek Recreation Area (Wikipedia)
Salt Creek Recreation Area is a 196-acre park located about 15 miles west of Port Angeles, Washington on U.S. Route 101 near the city of Joyce, Washington. The park was previously Camp Hayden, a World War II military camp built 1942–1945. The site was established as the Striped Peak Military Reservation in 1941, renamed as Camp Hayden on 22 October 1942, and renamed again as Fort Hayden on 17 April 1944. It was named for Brigadier General John Louis Hayden, a former commander of the Harbor Defenses of Puget Sound. It was purchased by the Federal General Services Administration after the war. There are still several structures left from the fort, including two large casemates which sheltered 16" guns and several other structures. The 16-inch battery was Battery 131, with two ex-Navy 16-inch Mark 2 guns capable of firing a one-ton projectile around 28 miles connected by a large magazine bunker. The camp also had Battery 249, which had two 6-inch guns with a bunker housing magazines and fire control equipment.
