Update: An article in The Oregonian featured Umbrella Falls, USGS Soapstone Lake (1985 ns) as being accessible 1/4-mile down a path from the Nehalem Fish Hatchery.
Wilson Falls, USGS Jordan Creek (1984 ns) is listed in the Geographic Names Information System database.  Its access is unclear, since it has not be mapped.
Roads are shown near North Fork Falls, USGS Hamlet (1984 nl) and Kilchis Falls, USGS Cedar Butte (1984).  The latter occurs along a very small stream, however.
