Abstract: Topographic map evidence is used to interpret landform origins in the Little Prickly Pear Creek-Missouri River drainage divide area located in Lewis and Clark County, Montana. The Missouri River flows in a north and north-northwest direction along the study region east boundary. Little Prickly Pear Creek flows in an east-northeast, north, and north-northeast direction […]
Abstract: This essay uses topographic map evidence to interpret landform origins along and near the Montana Marias River-Flathead River drainage divide segment of the east-west continental divide. The Marias River is an east-oriented Missouri River tributary with Missouri River water eventually reaching the Gulf of Mexico. Marias River tributaries including northeast-oriented Birch and Badger Creek […]
Abstract: Topographic map interpretation methods are used to interpret landform origins along the Montana Little Prickly Pear Creek-Blackfoot River drainage divide segment of North America’s east-west continental divide. Little Prickly Creek originates on the east side of the east-west continental divide and flows in an east, north, and north-northeast direction to join the Missouri River […]
A geomorphic history based on topographic map evidence Abstract: This is an overview essay for a series of essays describing drainage divide areas in and surrounding the Montana Teton River drainage basin. Essays describing specific Teton River drainage divide areas can be found listed under the sidebar Teton River category. The Teton River originates along the […]
Abstract: This essay interprets topographic map evidence to determine the origin of the east-west continental divide in the Montana Sun River-Flathead River drainage divide area. The Sun River is formed at the confluence of south-southeast and north-northwest tributaries and flows in an east direction to join the Missouri River at Great Falls, Montana with water […]
Abstract: This essay uses topographic map evidence to interpret landform origins in the Montana Teton River-Flathead River drainage divide area. Today the Teton River originates along the North America’s east-west continental divide and flows in a south-southeast and east direction to join the Missouri River with water eventually reaching the Gulf of Mexico. The northwest-oriented […]
A geomorphic history based on topographic map evidence Abstract: This essay is an overview of six essays describing drainage divide areas in and surrounding the Montana Sun River drainage basin. Essays are based on Sun River drainage basin topographic map evidence and are listed under the Sun River category (see sidebar category list). The Sun […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Missouri River drainage divide area located in Chouteau County, Montana. No effort has been made to introduce evidence from other sources. The Teton River originates in the Montana Rocky Mountains and flows in roughly an east direction onto the Montana plains […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Sun River drainage divide area of eastern Teton County, Montana. The Teton River and Sun River are east oriented Missouri River tributaries, both of which in Teton County originate along the east west continental divide and then flow from deep mountain […]
Abstract: Topographic map interpretation methods are used to determine landform origins in the Teton River-Sun River drainage divide area located in western Teton County. Western Teton County is a region of high mountains just east of the east-west continental divide while eastern Teton County is a plains region east of the mountain front. The Teton […]
