Essays describing specific Teton River drainage divide areas can be found listed under the sidebar Teton River category. The Teton River originates along the […]
Abstract: This essay interprets topographic map evidence to determine the origin of the east-west continental divide in the Montana Sun River-Flathead River drainage divide area. The Sun River is formed at the confluence of south-southeast and north-northwest tributaries and flows in an east direction to join the Missouri River at Great Falls, Montana with water […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the Montana Teton River-Flathead River drainage divide area. Today the Teton River originates along the North America’s east-west continental divide and flows in a south-southeast and east direction to join the Missouri River with water eventually reaching the Gulf of Mexico. The northwest-oriented […]
A geomorphic history based on topographic map evidence Abstract: This essay is an overview of six essays describing drainage divide areas in and surrounding the Montana Sun River drainage basin. Essays are based on Sun River drainage basin topographic map evidence and are listed under the Sun River category (see sidebar category list). The Sun […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Missouri River drainage divide area located in Chouteau County, Montana. No effort has been made to introduce evidence from other sources. The Teton River originates in the Montana Rocky Mountains and flows in roughly an east direction onto the Montana plains […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Sun River drainage divide area of eastern Teton County, Montana. The Teton River and Sun River are east oriented Missouri River tributaries, both of which in Teton County originate along the east west continental divide and then flow from deep mountain […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Sun River drainage divide area located in western Teton County. Western Teton County is a region of high mountains just east of the east-west continental divide while eastern Teton County is a plains region east of the mountain front. The Teton […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Sun River-Missouri River drainage divide area of Cascade County, Montana. The Missouri River flows in a northeast direction through Cascade County passing the communities of Cascade and Great Falls and is joined by north-northwest oriented tributaries from the south. The Sun River […]
Abstract: This is essay is an introduction to a collection of essays describing drainage divide areas in and surrounding the Montana Dearborn River drainage basin. This essay contains an overview of more detailed information contained in the five much more detailed essays, which can be found under the Dearborn River category (see sidebar). The Dearborn River […]
Abstract: Topographic map interpretation methods are used to determine Sun River-Dearborn River drainage divide area landform origins in eastern Lewis and Clark County, Montana. The Sun River originates along the east-west continental divide, which forms the Lewis and Clark County west border, and flows in an east direction to join the northeast-oriented Missouri River at […]
Abstract: Topographic map interpretation techniques are used to determine landform origins in the Sun River-Dearborn River drainage divide area located in western Lewis and Clark County, Montana. The Sun River originates in the Lewis and Clark Range along the east-west continental divide and flows in an east direction to join the northeast-oriented Missouri River. The […]
Abstract: This essay uses topographic map interpretation methods to determine landform origins in the South Fork Dearborn River-Missouri River drainage divide area located in Lewis and Clark County, Montana. No effort has been made to introduce evidence from other sources. The Missouri River flows in a north-northwest and north-northeast direction along the study region’s east […]
Abstract: This essay uses topographic map evidence to interpret Dearborn River-South Fork Dearborn River drainage divide area landform origins in Lewis and Clark County, Montana. The Dearborn River originates in the high Lewis and Clark Mountain Range along the east-west continental divide and flows in a southeast direction with some northeast-oriented segments to join a […]
Abstract: The “thick ice sheet that melted fast” geomorphology paradigm is being introduced in the Missouri River drainage basin research project essays by interpreting large quantities of previously neglected topographic map drainage divide evidence. Fundamental differences between the “thick ice sheet that melted fast” geomorphology paradigm and the prevailing geomorphology paradigm are related to number […]
Abstract: This essay uses topographic map evidence to interpret the east-west continental divide origin along the Montana Dearborn River-Blackfoot River drainage divide. The Dearborn River-Blackfoot River drainage divide is oriented in what might be considered a southeast direction along the crests of high mountain ridges at the south end of the Lewis and Clark Mountain […]
The Missouri River drainage basin research project is using topographic map interpretation methods to determine landform origins along approximately 500 different drainage divides within and surrounding the Missouri River drainage basin. A separate essay is made for each drainage divide area, which usually includes two location maps and eight examples of topographic maps along with […]
Abstract: Topographic map interpretation methods are used to determine erosional landform origins in the Shields River drainage divide area located in Gallatin and Park Counties, Montana. The Shields River is a south-southeast oriented tributary to the east and northeast oriented Yellowstone River and flows in a broad valley east of the Bridger Range and west […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Sixteenmile Creek-Gallatin River drainage divide area located in Gallatin County, Montana.
