The Rocky Mountain Trench, also known as the Valley of a Thousand Peaks or simply the Trench, is a large valley on the western side of the northern part of North America's Rocky Trench is both visually and cartographically a striking physiographic feature extending approximately 1, km (1, mi) from Flathead Lake, Montana to the Liard River, just south of the British Columbia Coordinates: 54°30′N °30′W / °N.

The Rocky Mountain Trench is a long and deep valley extending approximately 1, km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory.

Its predominantly flat floor is 3–20 km wide and ranges in elevation between m and 1, m above sea level. With walls made of. Rocky Mountain Trench, geological depression extending north-northwest for about miles (1, km) from western Montana, U.S., south of Flathead Lake, through British Columbia, Can., to the headwaters of the Yukon trench parallels the steep western face of the Rockies, separating them from the older western ranges.

PROBLEMS IN STRATIGRAPHY ALONG THE ROCKY MOUNTAIN TRENCH FRANCIS PARKER SHEPARD University of Chicago In an investigation of the structure of the Rocky Mountain trench, from Gateway, Montana, to Golden, British Columbia,' the writer came in contact with some of the stratigraphic problems of the Canadian Cordillera.

For determination of fossils. The trench, with a width that ranges from about 3 to 16 kilometers (2 to 10 miles), separates the Columbia Mountains on the west and the Canadian Rockies on the east. (Note that the image has been rotated so that north is to the right.) Exposed rock appears gray; forests are green; grain fields are yellow; snow-capped mountains are white.

between the Rocky Mountains on the east and a succession of ranges on the west. From what is known about the trench it has been estimated to have an average width from wall to wall of 5 miles. The portion of the trench which I studied was from Gateway, Montana, at the boundary line, to Golden, British Colum-bia, miles to the north.

The Rocky Mountain trench is one of the youngest, most prominent, and most enigmatic structures of the Canadian Cordillera.

With regards to sedimentology and stratigraphy, the work by Eric and his students aided in understanding the stratigraphic and sedimentary nature of Devonian time-equivalent deposits in the subsurface of Alberta.

The Laramide synorogenic strata of the Denver Basin record the uplift and denudation of the central and southern Front Range of the Rocky Mountains. Synorogenic sedimentation took place in two distinct pulses, the first spanning the Cretaceous–Tertiary boundary and extending into the early Paleocene.

Upper Cretaceous and lower Tertiary rocks compose the majority of this thick Phanerozoic section. The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins.

Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in. The Rocky Mountain Trench is widely known as a chain of interconnected linear valleys along the western side of the Rocky Mountains from Montana to near the British Columbia—Yukon boundary, a distance of about 1, km ().The valleys are characteristically steep sided, with relief of 1,–2, m.
