A collection of detailed research data based on topographic map evidence Abstract: The Missouri River drainage basin landform origins research project introduces a fundamentally new and different geomorphology paradigm by interpreting previously unexplained topographic map evidence to determine origins for all major Missouri River drainage basin drainage divides. Detailed essays illustrating and describing interpreted topographic […]

A geomorphic history based on topographic map evidence Abstract: The Big Dry Creek-Little Dry Creek drainage divide area discussed here is located in eastern Montana, USA. Although detailed topographic maps of the Big Dry Creek-Little Dry Creek drainage divide area have been available for more than fifty years detailed map evidence has not previously been […]
A geomorphic history based on topographic map evidence Abstract: The Beaver Creek-Birch Creek drainage divide area is located in Hill and Chouteau Counties, Montana, USA and includes high Bear Paw Mountain regions.Beaver Creek is a north oriented Milk River tributary and Birch Creek is a south-oriented Missouri River tributary. Although detailed topographic maps of the […]
A geomorphic history based on topographic evidence Abstract: The Rock River-Des Moines River drainage divide area is located in southwest Minnesota, USA. The Rock River flows south to the south-oriented Big Sioux River. The Des Moines River flows in a southeast direction along the crest of the northeast-facing Prairie Coteau escarpment and eventually joins the […]
Abstract: The Platte River-Medicine Creek drainage divide area in Lincoln and Frontier Counties, Nebraska contains evidence of massive south-oriented flood flow that occurred prior to Platte River valley headward erosion. Flood waters were probably derived from a rapidly melting North American ice sheet and initially flowed across a topographic surface at least as high as […]
Abstract: The Frenchman Creek-Republican River drainage divide area in Chase, Hayes, Dundy, and Hitchcock Counties, Nebraska was eroded by immense southeast and south-southeast oriented floods. Flood waters were probably derived from a rapidly melting North American ice sheet and originally flowed across southwest Nebraska and into Kansas and then further south to the Gulf of […]
Abstract: The Republican River-Solomon River drainage divide area in Cloud, Ottawa, Clay, and Dickinson Counties, Kansas was eroded by immense south-oriented floods. Flood waters were probably derived from a rapidly melting North American ice sheet and flowed across Nebraska into Kansas and at one time flowed further south. Headward erosion of the east-oriented Kansas River […]
Abstract: The North Fork Solomon River-South Fork Solomon River drainage divide in Norton, Phillips, Smith, Graham, Rooks, and Osborne Counties, Kansas was eroded by massive south-oriented floods which originally flowed across a topographic surface at least as high as the highest present day North Fork Solomon River-South Fork Solomon River drainage divide elevations. Flood waters […]
Abstract: The South Grand River-Osage River drainage divide area in Henry, St Clair, and Benton Counties is located upstream from Harry S. Truman Dam and Harry S. Truman Reservoir floods the South Grand River and Osage River valleys. The Osage River and South Grand River valleys and tributary valleys were eroded during immense south-oriented floods […]
Abstract: The Clear Creek-Sac River drainage divide area in St Clair, Vernon, and Cedar Counties, Missouri is located south of the east-oriented Osage River and was eroded by immense south-oriented floods prior to Osage River valley headward erosion. Flood waters were derived from a rapidly melting North American ice sheet and prior to Osage River […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the Boyer River-Nishnabotna River drainage divide area located in Crawford, Carroll, Shelby, and Audubon Counties, Iowa. Evidence presented and discussed also includes regions between Nishnabotna River tributaries located in the four counties. The Boyer River and Nishnabotna River are southwest and south-southwest oriented Missouri […]
Abstract: Topographic map interpretation methods are used to interpret East Fork Grand River-Thompson River drainage divide area landform origins in Worth, Gentry, and Harrison Counties, Missouri. The East Fork Grand River-Thompson River drainage divide area consists of multiple drainage divides between several narrow and elongate south-oriented Grand River tributary drainage basins. The East Fork Grand […]
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 landform origins in the Sixteenmile Creek-Gallatin River drainage divide area located in Gallatin County, Montana. Sixteenmile Creek is a southwest, northwest, and west oriented stream flowing between the Big Belt Mountains to the north and the Bridger Range to the south and flows to the north-oriented […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Smith River-Missouri River drainage divide area in Meagher and Broadwater Counties, Montana, which is also located in the Big Belt Mountains. The Missouri River flows in a north-northwest direction along the Big Belt Mountains west side and then turns to flow in […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Montana Missouri River-Smith River drainage divide area north of the Big Belt Mountains. The Missouri River flows in a north-northwest and northeast direction west and north of the Big Belt Mountains while the Smith River flows in a north and north-northwest direction […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Missouri River-Hound Creek drainage divide area in Lewis and Clark and Cascade Counties, Montana. The study region is today a region of high mountains and deep valleys located between the north-northwest and north-northeast oriented Missouri River and east and north-oriented Hound Creek. […]
