Withrow is an unincorporated community in Douglas County, Washington, United States. [1]

Named for a cattleman named J.J. Withrow, [2] Withrow lies at the base of the Withrow Moraine and Jameson Lake Drumlin Field is a National Park Service designated privately owned National Natural Landmark located in Douglas County, Washington state, United States. Withrow Moraine is the only Ice Age terminal moraine on the Waterville Plateau section of the Columbia Plateau. It lies on the terminal moraine for the Okanogan lobe of the Cordilleran Ice Sheet, which flowed southward through the Okanogan trough from the Interior Plateau of British Columbia blocking the course of the Columbia River and ending on the elevations of the Waterville Plateau.

Moraine Glacially formed accumulation of unconsolidated debris

A moraine is any accumulation of unconsolidated debris, sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines and medial moraines.

Columbia Plateau Plateau in Washington, Oregon, and Idaho in the United States

The Columbia Plateau is a geologic and geographic region that lies across parts of the U.S. states of Washington, Oregon, and Idaho. It is a wide flood basalt plateau between the Cascade Range and the Rocky Mountains, cut through by the Columbia River.

Channeled Scablands Landscape in eastern Washington state scoured by cataclysmic floods during the Pleistocene epoch

The Channeled Scablands at one time were 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 the U.S. state of Washington. The Channeled Scablands were scoured by more than 40 cataclysmic floods during the Last Glacial Maximum and innumerable older cataclysmic floods over the last two million years. These floods were periodically unleashed whenever a large glacial lake broke through its ice dam and swept across eastern Washington and down the Columbia River Plateau during the Pleistocene epoch. The last of the cataclysmic floods occurred between 18,200 and 14,000 years ago.

Sims Corner Eskers and Kames

Sims Corner Eskers and Kames National Natural Landmark of Douglas County, Washington and nearby McNeil Canyon Haystack Rocks and Boulder Park natural landmarks contain excellent examples of Pleistocene glacial landforms. Sims Corner Eskers and Kames National Natural Landmark includes classic examples of ice stagnation landforms such as glacial erratics, terminal moraines, eskers, and kames. It is located on the Waterville Plateau of the Columbia Plateau in north central Washington state in the United States.

Moses Coulee Canyon in the Waterville plateau region of Douglas County, Washington

Moses Coulee is a canyon in the Waterville plateau region of Douglas County, Washington. Moses Coulee is the second-largest and westernmost canyon of the Channeled Scablands, located about 30 kilometres (19 mi) to the west of the larger Grand Coulee. This water channel is now dry, but during glacial periods, large outburst floods with discharges greater than 600,000 m3/s (21,000,000 cu ft/s) carved the channel. While it's clear that megafloods from Glacial Lake Missoula passed through and contributed to the erosion of Moses Coulee, the origins of the coulee are less clear. Some researchers propose that floods from glacial Lake Missoula formed Moses Coulee, while others suggest that subglacial floods from the Okanogan Lobe incised the canyon. The mouth of Moses Coulee discharges into the Columbia River.

Withrow Moraine and Jameson Lake Drumlin Field

The Withrow Moraine and Jameson Lake Drumlin Field is a National Park Service–designated privately owned National Natural Landmark located in Douglas County, Washington state, United States. Withrow Moraine is the only Ice Age terminal moraine on the Waterville Plateau section of the Columbia Plateau. The drumlin field includes excellent examples of glacially-formed elongated hills.

The Old Cariboo Road is a reference to the original wagon road to the Cariboo gold fields in what is now the Canadian province of British Columbia. It should not be confused with the Cariboo Road, which was built slightly later and used a different route.

The Okanagan Basin spans two countries and comprises the basin of Okanagan Lake, the Okanogan River and tributary valleys such as that of the Similkameen and Chelan Rivers. In Canada the basin constitutes two distinct regions within British Columbia, the Similkameen Country to the west and the main Okanagan region running from the communities of Osoyoos in the south to Armstrong in the north – incorporating most of the three Okanagan regional districts and is usually known as "the Okanagan" or as the Okanagan Valley or the Okanagan Country. In the United States, the Okanogan Country is the western, lowland core of Okanogan County, which like its Canadian counterpart has a history and economy based on ranching, gold, fruit orcharding and vineyards, but the basin includes Lake Chelan and other flanking valleys. Communities in Washington's Okanogan Basin include Pateros, Omak, Okanogan, Oroville and Brewster.

The Mansfield Branch Line, located in Eastern Washington State, Douglas County, was constructed by the Great Northern Railway in 1909, and was completed in just 9 months. Starting from the Columbia River and ending in Mansfield, the 60.62 miles (97.56 km) of track cut through the southern portion of the Moses Coulee, snaked up Douglas Creek and made its way across the vast wheat fields of the Waterville Plateau. The train made scheduled stops at Palisades, Alstown, Douglas, Supplee, Withrow, Touhey and Mansfield to drop off and pick up loaded 40 ft (12 m) boxcars of grain from The Waterville Union Grain Co..

Okanagan Country

The Okanagan Country, also known as the Okanagan Valley, is a region located in the Canadian province of British Columbia and the U.S. state of Washington, defined by the basin of Okanagan Lake and the Okanagan River. With an estimated 400,000 residents, the Okanagan Country spans from the Thompson Plateau near Grindrod, British Columbia in the Okanagan to the Okanagan Highland near Douglas County, Washington in the Okanogan. The largest city in the Canadian portion is Kelowna, with a metropolitan population of 194,882 residents as of 2016, while the largest city in the American portion is Omak, with 4,881 residents as of 2011. The region took its current name in honor of the Okanagan term, ukʷnaqín. The mild climate and close proximity to lakes, rivers and mountainous regions make the Okanagan Country an outdoor recreational destination. The region's economy is dominated by the primary sector industries of agriculture and forestry, although economic diversification has also occurred with retirement communities and recreational tourism. The American portion is considered to be more remote than the Canadian division, with approximately 10 percent of the population.

Ice Age Floods National Geologic Trail

The Ice Age Floods National Geologic Trail is a network of routes connecting natural sites and facilities that provide interpretation of the geological consequences of the Glacial Lake Missoula floods of the last glacial period that occurred about 18,000 to 15,000 years ago. It includes sites in Washington, Oregon, Idaho, and Montana. It was designated as the first National Geologic Trail in the United States in 2009.
