A geomorphic history based on topographic map evidence Abstract: This overview essay provides highlights of more detailed essays illustrating and describing Iowa and Missouri Grand River drainage basin topographic map evidence which is then interpreted to determine Iowa and Missouri Grand River drainage basin landform origins (the Iowa and Missouri Grand River should not be […]
Abstract: The Missouri River-Osage River drainage divide area in Jackson and Cass Counties, Missouri is in reality the Missouri River-South Grand River drainage divide area with the South Grand River being a southeast-oriented Osage River tributary. The Missouri River-South Grand River drainage divide area was eroded by immense south oriented floods from a rapidly melting North […]
Abstract: The Missouri River-Gasconade River drainage divide in Osage and Gasconade Counties, Missouri is the drainage divide between the northeast and east oriented Missouri River and the Gasconade River, which is a northeast and north-northeast oriented Missouri River tributary. The Missouri River-Gasconade River drainage divide area was eroded by immense south-oriented floods derived from a […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the Des Moines River-Grand River drainage divide area located in Adair, Madison, Union, and Ringgold Counties, Iowa. The major drainage divide observed in the four county study region is the Middle River-Thompson River drainage divide, where the Middle River is a southeast and […]
Abstract: Topographic map evidence is used to interpret Des Moines River-Missouri River drainage divide area landform origins in Clarke, Lucas, and Monroe Counties, Iowa. Major Missouri River tributaries in the Clarke, Lucas, and Monroe County region are south-southeast oriented Thompson River and southeast oriented Chariton River with its east oriented Chariton Creek headwaters. Directly north of the […]
Abstract: Topographic map evidence is used to interpret the Platte River-Thompson River drainage divide area located in Adair, Union, Ringgold, and Decatur Counties, Iowa. The Grand River is a south-southwest, southeast, and south oriented Missouri River tributary which originates between the south-southwest oriented Platte River drainage basin and the south-southeast oriented Thompson River drainage basin […]
Abstract: Topographic map evidence is used to interpret landform origins in the Chariton River-Grand River drainage divide area located in Lucas, Decatur, and Wayne Counties, Iowa. The Chariton River flows in an east, northeast, and southeast direction in south central Iowa before entering the state of Missouri and then flowing in a south direction to […]
Abstract: Topographic map interpretation techniques are used to interpret drainage divide origins in the One Hundred and Two River-East Fork Grand River drainage divide area located in Nodaway, Worth, and Gentry Counties, Missouri. The study region is located in northwest Missouri along and/or near the Iowa-Missouri state line. Multiple south-oriented Missouri River tributaries, including the […]
Abstract: Topographic map interpretation methods are used to interpret landform origins in the Platte River-Grand River drainage divide area of Gentry, Andrew, and De Kalb Counties, Missouri. The Platte River is a south-oriented Missouri River tributary flowing through eastern Andrew County and has south-oriented tributaries originating in southwest Gentry County and flowing through western De […]
Abstract: Topographic map interpretation methods are used to interpret landform origins in the Shoal Creek-Missouri River drainage divide area located in Caldwell, Ray, and Carroll Counties, Missouri. Shoal Creek is a north-northeast and east oriented tributary to the southeast and south-southeast oriented Grand River, which flows to the east-northeast and southeast oriented Missouri River near Brunswick, […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Gand River-Missouri River drainage divide area of Livingston and Carroll Counties, Missouri. The Missouri River flows in an east-northeast direction along the Carroll County southern border while the Grand River flows in a southeast direction across Livingston County and then in a […]
Abstract: Topographic map interpretation methods are used to interpret landform origins in the Grand River-Shoal Creek drainage divide area located in Daviess, Caldwell, and Livingston Counties, Missouri. The Grand River is a south, southeast, and south oriented Missouri River tributary and flows in a southeast direction across Daviess and Livingston Counties before turning to flow in […]
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: Topographic map interpretation methods are used to interpret landform origins in the Thompson River-Medicine Creek drainage divide area located in Mercer, Grundy, and Livingston Counties, Missouri. The Thompson River and Medicine Creek are south-oriented drainage routes, which flow from southern Iowa across Mercer and Grundy Counties, Missouri to join the southeast-oriented Grand River in […]
Abstract: Topographic map interpretation methods are used to interpret Medicine Creek-Locust Creek drainage divide area landform origins in Putnam, Sullivan, and Linn Counties, Missouri. Medicine Creek and Locust Creek are streams originating in southern Iowa and flowing in a south direction across Putnam, Sullivan, and Linn Counties, Missouri (in that order) to join the southeast […]
Abstract: Topographic map interpretation methods are used to interpret landform origins in the Grand River-Chariton River drainage divide area located in Chariton County, Missouri. The Grand River and Chariton River are south-oriented tributaries flowing to the southeast-oriented Missouri River with the Grand River located west of the Chariton River. Mussel Fork is a south-oriented Chariton […]
