Niobrara River-North Loup River drainage divide area landform origins, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Niobrara River-North Loup River drainage divide area discussed here is located in northern Nebraska, USA. Although detailed topographic maps of the Niobrara River-North Loup River drainage divide area have been available for more than fifty years detailed map evidence has not previously been used to […]

Elkhorn River-Shell Creek drainage divide area landform origins in Antelope, Madison, Boone, and Platte Counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Elkhorn River-Shell Creek drainage divide area in Antelope, Madison, Boone, and Platte Counties was eroded by a massive southeast-oriented flood, which had a source northwest of the Elkhorn River-Shell Creek drainage divide area. The southeast-oriented flood flow was captured in southern Boone and Platte Counties […]

Elkhorn River-Loup River drainage divide area landform origins between Shell Creek and Beaver Creek, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Elkhorn River-Loup River drainage divide area between Shell Creek and Beaver Creek, Nebraska, was eroded by massive southeast-oriented floods, which before being beheaded by Elkhorn River headward erosion flowed to what was probably a newly eroded east-oriented Loup River-Platte River valley. Evidence supporting this interpretation […]

Beaver Creek-Cedar River drainage divide area landform origins between South Fork Elkhorn River and Loup River, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Beaver Creek-Cedar River drainage divide area between the South Fork Elkhorn River and the Loup River was eroded by a massive southeast-oriented flood. Evidence for the southeast-oriented flood flow is found in the present day orientation of southeast-oriented Beaver Creek and Cedar River valleys and […]

Elkhorn River-Loup River drainage divide area landform origins in Rock, Holt, and Garfield Counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Elkhorn River-Loup River drainage divide area in Rock, Holt, and Garfield Counties, Nebraska was eroded by a massive southeast-oriented flood, which also deposited deltaic sediments in the region. Subsequent eolian activity has created sand dunes and otherwise obscured the regional drainage history, although present day […]

Cedar River-North Loup River drainage divide area landform origins in Valley, Greeley, and adjacent counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The southeast-oriented Cedar River and North Loup River valleys in Valley, Greeley, and adjacent counties drain to the northeast-oriented Loup River, which flows along the north edge of the large northeast-oriented Platte River valley. Topographic map evidence demonstrates the southeast-oriented Loup River tributary valleys and their […]

Loup River-Platte River drainage divide area landform origins between Kearney and Columbus, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Loup River-Platte River drainage divide area between Kearney and Columbus records the history of two immense converging glacial melt water floods during their central Nebraska flood flow events. An immense southeast-oriented flood flowed from the northwest into Nebraska, where late during the flood history it […]

North Loup River-Middle Loup River drainage divide area landform origins in Valley, Sherman, and Howard Counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The North Loup River-Middle Loup River drainage divide area in Valley, Sherman, and Howard Counties was eroded by immense southeast-oriented floods, which eroded the southeast-oriented North and Middle Loup River valleys headward from what was a newly eroded and large northeast-oriented Loup River-Platte River valley. Evidence […]

Middle Loup River-Mud Creek drainage divide area landform origins in Custer, Valley, and Sherman Counties, Nebraska, USA

A geomorphic history based topographic map evidence Abstract: The Middle Loup River-Mud Creek drainage divide area in Custer, Valley, Sherman Counties, Nebraska was eroded by an immense southeast-oriented flood that flowed across the entire drainage divide area. Initially flood waters flowed across a topographic surface at least as high as the highest drainage divide elevations […]

Mud Creek-South Loup River drainage divide area landform origins in Custer, Sherman, and Buffalo Counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The Mud Creek-South Loup River drainage divide area in Custer, Sherman, and Buffalo Counties was eroded by immense southeast-oriented floods , which initially flowed on a topographic surface at least as high as the highest drainage divide elevations today. Evidence supporting this flood erosion interpretation includes […]

South Loup River-Platte River drainage divide area landform origins in Logan, Lincoln, Custer, and Dawson Counties, Nebraska, USA

A geomorphic history based on topographic map evidence Abstract: The South Loup River-Platte River drainage divide area in Logan, Lincoln, Custer, and Dawson Counties, Nebraska, was eroded by a massive southeast and south-southeast oriented flood flowing across the entire drainage divide area. Evidence for the flood flow is seen in present day valley alignments, large […]
