The Palouse Falls lies on the Palouse River, about 4 mi (6 km) upstream of the confluence with the Snake River in southeast Washington, United States. The falls are 198 ft (60 m) in height. The falls consists of an upper falls with a drop of ~20 feet (6.1 m) which lies 1,000 feet (305 m) north-northwest of the main drop, and a lower falls, with a drop of 198 feet (60 m).

Geology
The canyon at the falls is 115 meters (377 feet) deep, exposing a large cross-section of the Columbia River Basalt Group. These falls and the canyon downstream are an important feature of the channeled scablands created by the great Missoula Floods that swept periodically across eastern Washington and across the Columbia River Plateau during the Pleistocene epoch.
The ancestral Palouse river flowed through the currently dry Washtucna Coulee to the Columbia River. The Palouse Falls and surrounding canyons were created when the Missoula Floods overtopped the south valley wall of the ancestral Palouse River, diverting it to the current course to the Snake River by erosion of a new channel.
The area is characterized by interconnected and hanging flood-created coulees, cataracts, plunge pools, kolk created potholes, rock benches, buttes and pinnacles typical of scablands. Palouse Falls State Park is located at the falls, protecting this part of the uniquely scenic area.
Economic proposals
In 1984, the Franklin County Public Utility District proposed a 30 m (98 ft) high dam be constructed upstream of the falls, allowing for a significant hydraulic head for hydroelectric power generation. This would have provided over one-third of the county's power and would have reduced ratepayer charges substantially. However, the majority of the ratepayers declined to approve the investment, preserving this geologically significant feature.
Palouse Falls State Park
The falls are included in Washington State's Palouse Falls State Park, which provides access to the falls and has displays explaining the region's unique geology, as well as its historical ties (the Palouse Indians and the Mullan Road both took advantage of the easy access to the plateau in the vicinity of the falls).
Kayaking
On April 21, 2009, Tyler Bradt ran the falls in a kayak setting an unofficial world record for the highest waterfall run. Bradt's media agent released the video footage of him dropping over the falls to Sports Illustrated, who carried it on their website. The magazine carried a two-page photo of the feat in its May 18 issue. The photos were also reproduced in Spain's Hola magazine's international issue of September 23, 2009.
Height of the falls
As a result of the unofficial world record for the highest waterfall run, questions were raised about the correct height of the main drop for the falls. In the interest of claiming a world record, Bradt's team measured the falls and determined the height was 186 feet (57 m) from the top pool immediately above main drop to the plunge pool immediately below. A regional paper, The Spokesman-Review inquired with Washington state officials and determined that the previous height measurement was performed in 1945 using earlier techniques; the state was not prepared to perform an updated measurement using laser surveying equipment. However, a Whitman College geology professor led a team of students who determined:
Official State Waterfall
On February 12, 2014, the Washington State House of Representatives passed HB 2119 unanimously to make Palouse Falls the official state waterfall in Washington State. The proposal for the bill originated when a group of elementary school students in the nearby town of Washtucna lobbied the state legislature.
