A view through a coulee in Alberta, with steep but lower sides, and water in the bottom. Coulee, or coulée (/ ˈ k uː l eɪ / or / ˈ k uː l iː /), [1] is any of various different landforms, all of which are kinds of valleys or drainage zones. The word coulee comes from the Canadian French coulée, from French couler 'to flow'.
It is the largest water reclamation project in the United States, supplying irrigation water to over 670,000 acres (2,700 km 2) of the 1,100,000 acres (4,500 km 2) large project area, all of which was originally intended to be supplied and is still classified irrigable and open for the possible enlargement of the system.
The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state.
No clear connection between the head of the coulee and major flood routes to the north, east, or west is known. Some researchers propose that floods from glacial Lake Missoula formed Moses Coulee, [2] while others suggest that subglacial floods from the Okanogan Lobe incised the canyon. [3] The mouth of Moses Coulee discharges into the Columbia ...
Grand Coulee is two canyons, with an open basin in the middle. The Upper Coulee, filled by Banks Lake, is 25 miles (40 km) long with walls 800 to 900 feet (240 to 270 m) tall. It links to the Columbia River at Grand Coulee Dam and leads southward, through the surrounding highlands. The entry to the coulee is 650 feet (200 m) above the Columbia.
Dry Falls is a 3.5-mile-long (5.6 km) scalloped precipice with four major alcoves, in central Washington scablands.This cataract complex is on the opposite side of the Upper Grand Coulee from the Columbia River, and at the head of the Lower Grand Coulee, northern end of Lenore Canyon. [1]
map showing location of Kennedy Coulee and other sites where Brachylophosaurus fossils have been found. The Kennedy Coulee (or "Kennedy's Coulee") is a coulee – a dry gorge or valley – in northern Montana and southern Alberta. [1] Its exposed rocks of the Judith River Formation are a rich source of fossils. [2]
As in the upper Grand Coulee, the raging river yanked chunks of rock from the face of the falls and the falls eventually retreated to their present location. Dry Falls is 5.6 km (3.5 mi) wide, with a drop of more than 120 m (400 ft).
