A geomorphic history based on topographic evidence Abstract: The Ponca Creek-Keya Paha (and Niobrara) River drainage divide area discussed here is located along the South Dakota-Nebraska border, USA. Although detailed topographic maps of the Ponca Creek-Keya Paha (and Niobrara) River drainage divide area have been available for more than fifty years detailed map evidence has […]
A geomorphic history based on topographic map evidence Abstract: The Bazile Creek-North Fork Elkhorn River drainage divide area is located in Knox, Pierce, and Antelope Counties, northeast Nebraska. USA. Bazile Creek flows in a north and north-northwest oriented direction to join a northeast-oriented segment of the southeast-oriented Missouri River. The North Fork Elkhorn River flows […]
A geomorphic history based on topographic map evidence Abstract: The Bow Creek-Logan Creek and other drainage divides in Cedar, Dixon, and Dakota Counties are located in northeast Nebraska between the southeast oriented Missouri River and the southeast oriented Elkhorn River. Bow Creek is a northeast and north oriented Missouri River tributary and Logan Creek is a southeast […]
A geomorphic history based on topographic map evidence Abstract: The Logan Creek-Missouri River drainage divide area in Dakota, Thurston, and Burt Counties is located in northeast Nebraska, USA. Logan Creek is a southeast and south oriented Elkhorn River tributary located west of the south-southeast Missouri River. Through valleys link north-oriented (barbed) Missouri River tributary valleys with […]
A geomorphic history based on topographic evidence Abstract: The Elkhorn River-Missouri River drainage divide area in Washington, Douglas, and Sarpy Counties, Nebraska is drained by the southeast-oriented Papillion Creek valley stem, which is located between the south oriented Elkhorn and Missouri River valleys. The south oriented Elkhorn River is located west of the Missouri River and flows […]
A geomorphic history based on topographic map evidence Abstract: The Platte River-Missouri River drainage divide area in Cass, Lancaster, and Otoe Counties, Nebraska was eroded by massive southeast and south oriented floods at the time the deep Missouri River valley eroded headward into the region. Flood waters were probably melt water floods from a rapidly melting […]
A geomorphic history based on topographic map evidence Abstract: The Little Nemaha River-Big Nemaha River drainage divide area is located in the Nebraska southeast corner and was eroded by an immense southeast and south oriented flood at the time the Missouri River valley and its tributary valleys were first eroding headward into Nebraska. The Big […]
A geomorphic history based on topographic map evidence Abstract The Big Blue River-Big Nemaha River drainage divide area in southeast Nebraska was eroded by massive south and southeast oriented floods. Floods were probably from a rapidly melting ice sheet located north and northwest of the drainage divide area. Initially flood waters flowed across a topographic […]
A geomorphic history based on topographic map evidence Abstract: The South Fork Big Nemaha River-Missouri River drainage divide area in Richardson County, Nebraska and Nemaha, Brown, and Doniphan Counties, Kansas was eroded by massive southeast and south oriented floods. Flood waters were probably derived from a rapidly melting thick North American ice sheet located north and […]
A geomorphic history based on topographic map evidence Abstract: The Big Blue River-South Fork Big Nemaha River drainage divide in Pawnee County, Nebraska and Marshall and Nemaha Counties, Kansas was eroded by immense southeast and south oriented floods, which were probably derived from a rapidly melting North American ice sheet. The present day north-oriented South-Fork Big […]
