HUNTTING, Supervisor Bulletin No. 45 WASHINGTON'S CHANNELED SCABLAND By .T HARLEN BRETZ l•or sate by Department or Conservation, Olympia, Washington. Price, 50 cents. FOREWORD Most travelers who have driven through eastern Washington have seen a geologic and scenic feature that is unique-nothing like it is to be found anywhere else in the world. This is the Channeled Scab­ land, a gigantic series of deeply cut channels in the erosion-resistant Columbia River basalt, the rock that covers most of the east-central and southeastern part of the state. Grand Coulee, with its spectac­ ular Dry Falls, is one of the most widely known features of this ex­ tensive set of dry channels. Many thousands of travelers must have wondered how this Chan­ neled Scabland came into being, and many geologists also have speculated as to its origin. Several geologists have published papers outlining their theories of the scabland's origin, but the geologist who has made the most thorough study of the problem and has ex­ amined the whole area and all the evidence having a bearing on the problem is Dr. J Harlen Bretz.

Montane mixed conifer forest, upland aspen forest, and lodgepole pine forests are present in the high elevations along with montane coniferous wetlands. Timber management is an important land use in the Subbasin on Tribal, state, federal, and private timberlands. Agriculture and grazing are other dominant land uses, particularly within the Colville River valley, on the plateaus above Lake Roosevelt, and in the extreme southern portion of the Subbasin. The largest urban areas in the Subbasin boundary include Chewelah, Colville, Kettle Falls, Davenport, and Grand Coulee.

  • The Missoula Flood
    THE MISSOULA FLOOD Dry Falls in Grand Coulee, Washington, was the largest waterfall in the world during the Missoula Flood. Height of falls is 385 ft [117 m]. Flood waters were actually about 260 ft deep [80 m] above the top of the falls, so a more appropriate name might be Dry Cataract.

One lobe of the ice sheet dammed the Columbia River, creating Lake Columbia and diverting the Columbia River into the Grand Coulee. Another lobe of the ice sheet advanced southward down the Purcell Trench to the present Lake Pend Oreille in Idaho and dammed the Clark Fork River. This created an enormous Lake Missoula, with a volume of water greater than that of Lake Erie and Lake Ontario combined [530 mi3 or 2200 km3].
