Valley Falls is a small unincorporated community in Lake County, Oregon, United States. The settled area is located at the junction of U.S. Route 395 and Oregon Route 31. The community is named for a small falls on the Chewaucan River just north of the occupied site. East of Valley Falls, the cliff face of Abert Rim overlooks the community.
The area around Valley Falls was occupied by Native Americans for up to 11,000 years prior to the arrival of white settlers. Archaeological evidence shows that the peak period for use by native tribes was between 2,000 and 500 years ago. During that period, the people who lived in the Valley Falls area were probably ancestors of the Klamath and Modoc peoples. Most of these Native Americans lived in pit-houses along the shore of Abert Lake, just north of Valley Falls.[1] There are also a number of ancient petroglyphs near Valley Falls. The Abert Lake Petroglyphs, at the foot of Abert Rim, are thought to be over 10,000 years old.[2]
In 1832, John Work led his Hudson's Bay Company trapping brigade through the Valley Falls area. Work recorded the visit in his journal. In 1843, Captain John C. Fremont explored the area around Valley Falls. Fremont name Abert Rim and nearby Abert Lake after the head of the United States Army's topographical engineers, Colonel John J. Abert.[3] [4]
The community was founded and named by C. W. E. Jennings, who opened a store at the site around 1908. It was named for a small falls on the Chewaucan River approximately 1miles north of the community. In 1909, a post office was established at Valley Falls. The office was located near the base of Abert Rim. The first postmaster was Ernest L.H. Meyer. However, Jennings later took over from Meyer. At its peak, the community of Valley Falls had a hotel, livery stable, and a dance hall in addition to the Jennings' store and post office. The area was surveyed for a railroad, but it was never built. In 1942, the post office was moved approximately one mile west to the junction of U.S. Route 395 and Oregon Route 31. The Valley Falls post office was closed in 1943.[5] [6] [7]
The unincorporated community of Valley Falls is located at the junction of U.S. Route 395 and Oregon Route 31 in the high desert country of Lake County in south-central Oregon. There are only five structures at the site. Valley Falls is 23miles north of Lakeview, Oregon, on Route 395; 23miles southeast of Paisley, Oregon, on Route 31; and 116miles southwest of Burns, Oregon, on Route 395.[8] [9] [10] [11]
Abert Rim is approximately one mile east of Valley Falls. The rim is one of the highest escarpments in the United States, rising 2500feet above the valley floor. The top 800feet is a sheer-cliff. The rim cliff runs over 30miles from north to south, making it the longest exposed block fault scarp in North America. The rim is basalt, formed by large lava flows during the Miocene epoch. After the lava flows stopped, large blocks faults broke and tilted the land. Abert Rim is the result of one of those giant faults.[1] [9] [12] [13]
From Valley Falls, visitors have an unobstructed view of Abert Rim's cliff face.[10] Along the highway just south of the Valley Falls, there is an Outback Scenic Byway kiosk that explains how Abert Rim was formed.[1] There are also two geological information signs north of Valley Falls, one on Route 395 and the other on Route 31.[14]

A populated place is usually not incorporated and by definition has no legal boundaries."[20] United States Census data are not available for Valley Falls.
