Abstract: This essay uses topographic map evidence to interpret landform origins in the North Platte River-Little Snake River drainage divide in the Wyoming and Colorado Sierra Madre Mountains. The Sierra Madre Mountains are a northwest to southeast oriented mountain range straddling the Wyoming-Colorado border. The North Platte River flows in a north-northwest direction on […]

Abstract: This essay uses topographic map evidence to identify north to south and northwest to southeast oriented through valleys crossing the North Platte River-Little Snake River drainage divide in the Wyoming northern Sierra Madre Mountains. The North Platte River flows in a north-northwest direction from Colorado into Wyoming along the east side of the […]
Abstract: Topographic map evidence in the Separation Creek-Little Sage Creek drainage divide area along the Wyoming Great Divide Basin east rim is illustrated and interpreted to determine erosional landform origins. The Great Divide Basin is a large region of internal drainage along the east-west continental divide in south central Wyoming and Separation Creek is […]
Abstract: Topographic map evidence in the Separation Creek-North Platte River drainage divide area along the Wyoming Great Divide Basin east rim is illustrated and discussed to determine the origin of the regional erosional landforms. Today the Great Divide Basin is a large region of internal drainage located along the east-west continental divide. The North […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the Sweetwater River-Great Divide Basin drainage divide area located near the Wyoming Ferris Mountains. The Ferris Mountains are a west-northwest to east-southeast oriented mountain ridge located between Green Mountain to the west and the Seminoe Mountains to the southeast. The Sweetwater River flows […]
Abstract: Topographic map evidence in the Sweetwater River-Lost Creek drainage divide area near Green Mountain in Wyoming is illustrated and discussed to determine the origin of the regional erosional landforms, including drainage routes and water and wind gaps. Green Mountain is a northwest to southeast oriented mountain south of the east oriented Sweetwater River […]
Abstract: This essay uses topographic map evidence to identify north to south and northwest to southeast oriented through valleys crossing the Sweetwater River-Great Divide Basin drainage divide in the region between the Wind River Range to the west and Crooks Mountain to the east. North of the Sweetwater River segment investigated is the Wind […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between Deer Creek and Sweetwater River tributaries at the Beaver Divide eastern end in central Wyoming. The Beaver Divide is a north-facing escarpment and the drainage divide between north-oriented drainage routes to the Wind River and south oriented drainage routes […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between North Platte River tributaries and the Sweetwater River in the Rattlesnake Hills in Natrona County, Wyoming. The North Platte River flows in a north and northeast direction between the Rattlesnake Hills to the west and the Laramie Mountains to the […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between Salt Creek and the North Platte River in central Wyoming. The study region is located north of an east oriented North Platte River segment located just north of the northwest end of the Laramie Mountains. The North Platte River […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between Casper Creek and the North Platte River in Natrona County, Wyoming. The North Platte River flows in a north and northeast direction to the northwest end of the Laramie Mountains and then turns to flow in an east and […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between South Fork Powder River and Casper Creek in Natrona County, Wyoming. The South Fork Powder River and Middle Fork Casper Creek and their tributaries originate in the Rattlesnake Hills and flow in northeast directions parallel to each other before […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the region between the Wind River and the Powder River south of the Bighorn Mountains. A broad low relief west-to-east oriented through valley between the Bighorn Mountains to the north and the Rattlesnake Hills to the south links the north-northeast oriented South […]
A geomorphic history based on topographic maps Abstract: This overview essay provides highlights from more detailed essays illustrating and describing topographic map evidence which is interpreted to determine origins of drainage divides between all major Platte River tributary drainage basins and Platte River drainage divides with all major adjacent drainage basins. Detailed essays upon which […]
A geomorphic history based on topographic map evidence Abstract: The Niobrara River-North Platte River drainage divide area is located in eastern Wyoming and western Nebraska, USA. Although detailed topographic maps of the Niobrara River-North Platte River drainage divide area have been available for more than fifty years detailed map evidence has not previously been used […]
A geomorphic history based on topographic map evidence Abstract: The Cheyenne River-North Platte River drainage divide area is located in eastern Wyoming, USA and is actually the drainage divide area between a Cheyenne River tributary, Lightning Creek, and the North Platte River. Although detailed topographic maps of the Lightning Creek-North Platte River drainage divide area […]
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 […]
