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 Elkhorn River-Logan Creek drainage divide area in Wayne, Stanton, and Cuming Counties is located in northeast Nebraska, USA. The Elkhorn River generally flows in a southeast and south direction to join the Platte River slightly west of Omaha and the Platte River then flows south […]
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 evidence Abstract: The Elkhorn River-Platte River drainage divide area located in Stanton, Cuming, Colfax, and Dodge Counties, Nebraska is primarily drained by south-southeast and east oriented Maple Creek, southeast-oriented Pebble Creek, and east-oriented Rawhide Creek drainage systems, all of which flow to the south-southeast oriented Elkhorn River. Landform evidence […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
A geomorphic history based on topographic map evidence Abstract: Topographic map interpretation methods are used to determine Loup River-Platte River drainage divide area landform origins in the Nebraska Sand Hills region. Headwaters of major Loup River tributaries originate in the Nebraska Sand Hills region and flow in an east direction before turning to flow in […]
A geomorphic history based on topographic map evidence Abstract: Topographic map interpretation methods are used to determine landform origins in the Snake Creek-North Platte River drainage divide area south and east of Alliance, Nebraska. The Snake Creek-North Platte River drainage divide area south and east of Alliance is located in the western Nebraska Sand Hills […]
A geomorphic history based on topographic map evidence Abstract: The Snake Creek-North Platte River drainage divide west and south of Alliance, Nebraska was crossed by an immense southeast-oriented flood. Evidence for the flood flow is found north and west of the east-oriented Snake Creek valley and also in and along the southeast-oriented North Platte River […]
A geomorphic history based on topographic map evidence Abstract: The Platte River-Wahoo Creek drainage divide area was eroded by a massive south-southeast oriented flood, with flood waters systematically captured by headward erosion of the Wahoo Creek valley and tributary valleys and subsequently captured by headward erosion of the Platte River valley. Flood waters eroded a […]
A geomorphic history based on topographic evidence Abstract: The Platte River-Salt Creek drainage divide area in Butler, Saunders, and Lancaster Counties was eroded by an immense south-southeast and southeast oriented flood. Flood waters were first captured by headward erosion of the south-southeast and east oriented Platte River valley and the southeast-oriented Wahoo Creek valley from […]
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 Platte River-Big Blue River drainage divide area in Hamilton, Polk, Butler, York, and Seward Counties was eroded by a massive east oriented flood, which was first captured by headward erosion of the south-southeast oriented Big Blue River and later captured by headward erosion of the deeper […]
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 […]
