Abstract: This essay uses topographic map evidence to interpret landform origins in the region between Little Blackfoot River and the Missouri River along the east-west continental divide in Lewis and Clark and Powell Counties, Montana. East of the continental divide the Missouri River flows in a north-northwest direction in eastern Lewis and Clark County before […]
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 […]

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 […]

Abstract: Topographic map interpretation methods are used to determine Sun River-Dearborn River drainage divide area landform origins in eastern Lewis and Clark County, Montana. The Sun River originates along the east-west continental divide, which forms the Lewis and Clark County west border, and flows in an east direction to join the northeast-oriented Missouri River at […]
Abstract: Topographic map interpretation techniques are used to determine landform origins in the Sun River-Dearborn River drainage divide area located in western Lewis and Clark County, Montana. The Sun River originates in the Lewis and Clark Range along the east-west continental divide and flows in an east direction to join the northeast-oriented Missouri River. The […]
Abstract: This essay uses topographic map interpretation methods to determine landform origins in the South Fork Dearborn River-Missouri River drainage divide area located in Lewis and Clark County, Montana. No effort has been made to introduce evidence from other sources. The Missouri River flows in a north-northwest and north-northeast direction along the study region’s east […]
Abstract: This essay uses topographic map evidence to interpret Dearborn River-South Fork Dearborn River drainage divide area landform origins in Lewis and Clark County, Montana. The Dearborn River originates in the high Lewis and Clark Mountain Range along the east-west continental divide and flows in a southeast direction with some northeast-oriented segments to join a […]
Abstract: This essay uses topographic map evidence to interpret the east-west continental divide origin along the Montana Dearborn River-Blackfoot River drainage divide. The Dearborn River-Blackfoot River drainage divide is oriented in what might be considered a southeast direction along the crests of high mountain ridges at the south end of the Lewis and Clark Mountain […]
