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