can be determined, a geographic feature was named for every Corps member, including Seaman, Lewis's Newfoundland dog. In 1806, on the return leg of the expedition down the Yellowstone River, Clark also named another geographical feature for York, "York's Dry Creek", a tributary of the Yellowstone River in Custer County, Montana. This name did not stick, however, and the creek became known as "Custer Creek". Official recognition of nomenclature "Yorks Islands" Though the name for "Yorks 8 Islands" appears on Clark's 1805 maps of the expeditions travel along the Missouri for July 24, 1805, the geographical designation for "Yorks Islands" was not officially confirmed until 2000, when the U.S. Board on Geographic Names approved the name Yorks Islands for the group of Missouri River islands in Broadwater County. The name was also approved by the Montana Board on Geographic Names and has been entered into the Nation's official automated geographic names repository. The USGS (United States Geological Survey) Geographic Names Information System has settled on "Yorks Islands". However, the area is also called "York's Islands", or simply "York Island". Designation of "York's Islands Fishing Access Site" The island group are now incorporated into "York's Islands Fishing Access Site", maintained by the Montana Fish, Wildlife and Parks Department. This site is located on 22 acres along the east side of Missouri River 4 miles south of Townsend. The site is just off of U.S. Highway 287. The site is marked by a Montana Fish and Wildlife Department sign. It includes a boat launch, picnic tables, fishing access, camping sites (including some for small trailers) and toilets. There is a small fee. There is no water or any other services.
