The Red River Valley
by Don McCollor


The Valley. The Red River Valley. More properly the Valley of the Red River of the North to distinguish it from the southern Red River bordering Texas and Oklahoma. The Red River of the North flows sluggishly north down the center of the Valley, which is not a valley but rather the level bed of an ancient glacial lake. The Valley is many things. Where the West begins. The borderland tallgrass prairie between forest and the dryer land west of the hundredth meridian. Flat level land, where the earth curves away beneath an endless empty sky. Rich land, deep lake silt soil with a fertility equaled only by the valley of the Nile. A climate shared with the rest of the great plains--extremes of heat and cold and sudden changes. And the wind, as much a part of the Valley as the sky and soil.


The Valley begins at the border of South Dakota and Minnesota at Big Stone Lake, following the course of the Red River forming the border of Minnesota and North Dakota, crossing into Canada to the mouth of the Red River in Lake Winnipeg. Forty to fifty miles wide and three hundred miles long, the Valley is bound by low rising ridges of sand and gravel marking the shorelines of the glacial lakes that spawned it.

The Valley is young, born of ice and water of the last continental glaciation. One lobe of the Laurentide ice sheet thrust south along what is now the course of the Red River, stripping away the older rock layers of the past, in places scouring down to the ancient bedrock of the Precambrian. As the ice retreated, the meltwaters pooled to form the glacial lake known as Agassiz. Hemmed by high ground to the south and the ice to the north, Agassiz grew to spread across the Valley into northern Minnesota and far north into Canada. A giant, larger than the five Great Lakes combined. Agassiz's waves thundered against beaches to raise sand and gravel ridges that now mark the boundaries of the Valley. The torrents of mighty rivers flowed into and out of Agassiz, carving the Minnesota River Valley, the Pembina Gorge, forming the Sheyenne and Assiniboine deltas. With inflowing waters came silt deposited as level sediment on the lake bottom, sometimes scores of feet thick, burying the rock and glacial debris under what would become some of the richest soil on earth. The Valley has a continental climate, with extremes of temperature and powerful storms. Temperatures exceeding +100 degrees F in summer and -40 degrees F in the winter are not common, but not unusual. More importantly, the moisture--rain and snow--is not enough for forests to grow, but adequate for unirrigated farming. Before the crops, the Valley was a tallgrass prairie. Grass higher than the head of a man, waving in the wind like billows of a sea.

Like the flow of the Red River, much of the recent history of the Valley faces north. The first European settlement was founded by Lord Selkirk at the juncture of the Red River and the Assiniboine where the city of Winnipeg now stands. Nestled in the level prairie, the tree-lined courses of rivers and streams held a bounty of animal furs. And in season, long caravans of Red River ox carts with high wooden ungreased wheels creaked and squealed along the Valley trails--from Winnipeg and Fort Gary down the Red River Valley, then down the Minnesota River valley to the Fort Snelling and the frontier village of St. Paul. Travel on the prairie is as on the sea. The groves along small rivers and streams represented safety--firewood, water, and shelter--with every effort made not to be overtaken by thunderstorm or blizzard on the open prairie. Later, the ox carts (and dog sleds in winter) gave way to threshing steamboats churning round the thousand bends of the Red River. In turn, the steamboats gave way to the railroads, bringing waves of settlers into the Valley. Railroad land grants and the introduction of mechanical farm machinery gave birth to corporate Bonanza farms. Agriculture on a giant scale. Wheat fields-not farms-fields a mile square. The Grandin farm--95 square miles--carried wheat on their own steamboats south to railhead at Fargo to be stored in their own elevator complex.

The Valley has changed much, but appears unchanging. Like the geology, it is best seen from the sky. The tallgrass prairie and buffalo are gone, replaced by a patchwork of fields. Lines of shelterbelts march in orderly rows--for except along the river courses nearly every tree has been carefully planted. Also almost unnoticed is the massive network of drainage ditches, for the level Valley floor once held shallow wetlands by the hundreds. Water, carrying fertilizers, chemicals and soil winds its way to the Red River more quickly today, and increases the severity of its seasonal floods. Yet the Valley remains, level and timeless in its seasons.
