Abstract: The Hackberry Creek-Smoky Hill River drainage divide in Logan and Gove Counties, Kansas was crossed by immense south and east oriented floods. Flood waters were probably derived from a rapidly melting North American ice sheet and flowed southward across Nebraska and into Kansas. The Smoky Hill River valley was the southernmost of several deep […]

Abstract: The Ladder Creek-White Woman Creek drainage divide area in Wallace, Greeley, Wichita, and Scott Counties, Kansas was eroded by immense south-oriented floods and by immense east and southeast oriented floods, which also probably deposited significant flood transported sediments. Flood waters were derived from a rapidly melting North American ice sheet and the south-oriented flood waters […]
Abstract: The Smoky Hill River-Arkansas River drainage divide area in Ellsworth, Rice, and Mc Pherson Counties, Kansas was eroded by immense south-oriented floods. Flood waters were derived from a rapidly melting North American ice sheet and flowed south into Kansas where they were captured by headward erosion of deep valleys in sequence (from south to […]
Abstract: The Kansas River-Marais des Cygnes River drainage divide area in Johnson and Miami Counties is the divide between the Kansas River drainage basin to the north and the Osage River drainage basin to the south. The drainage divide area was eroded by immense south oriented floods derived from a rapidly melting North American ice […]
Abstract: The Missouri River-Osage River drainage divide area in Jackson and Cass Counties, Missouri is in reality the Missouri River-South Grand River drainage divide area with the South Grand River being a southeast-oriented Osage River tributary. The Missouri River-South Grand River drainage divide area was eroded by immense south oriented floods from a rapidly melting North […]
Abstract: The Missouri River-Blackwater River drainage divide in Lafayette and Johnson Counties, Missouri is a west to east oriented drainage divide between the east-northeast and southeast oriented Missouri River to the north and the east, northeast, and east oriented Blackwater River to the south. The drainage divide area was eroded by immense south oriented floods derived […]
Abstract: The Little Sac River-James River drainage divide area in Dade, Polk, and Greene Counties, Missouri is the divide between the Missouri River drainage basin to the north and the White River drainage basin to the south. The drainage divide area was eroded by immense south-oriented flood flow from a rapidly melting North American ice […]
Abstract: The Weaubleau Creek-Little Sac River drainage divide area in St Clair, Hickory, Cedar, and Polk Counties, Missouri is located south of the Osage River and east of the Sac River and is drained primarily by north and northwest oriented streams. The north and northwest oriented stream valleys were eroded during a massive reversal of […]
Abstract: The Osage River-Weaubleau Creek drainage divide in St Clair, Benton, and Hickory Counties is bounded on the east by the north-oriented Pomme de Terre River, on the west by north, northwest, and north oriented Weaubleau Creek, and on the north by the east-oriented Osage River, and is drained primarily by north-oriented streams. North-oriented valleys […]
Abstract: The Little Sac River-Pomme de Terre River drainage divide area in Polk, Dallas, Greene, and Webster Counties, Missouri is the drainage divide between two north-oriented Osage River tributaries and evolved during a massive reversal of an immense south-oriented flood. South-oriented flood waters were derived from a rapidly melting North American ice sheet and flowed […]
Abstract: The Osage River-Little Niangua River drainage divide area in Benton, Camden, Hickory, and Dallas Counties, Missouri is bounded by the Osage River in the north, the Pomme de Terre River in the west, and the north and east oriented Little Niangua River, which flows into the north-oriented Niangua River, in the east and south. […]
Abstract: The Pomme de Terre River-Niangua River drainage divide area in Polk, Dallas, and Webster Counties, Missouri is the southern half of the drainage divide between two north-oriented Osage River tributaries and was eroded and created during a massive reversal of an immense south oriented flood. The south oriented flood waters were derived from a rapidly melting […]
Abstract: The Osage River-Dry Auglaize Creek drainage divide area in Camden, Miller, and Laclede Counties, Missouri is bounded on the north by the east oriented Osage River, on the west by the north oriented Niangua River, and on the east and south by north and east-northeast oriented Dry Auglaize Creek, and was eroded by a massive reversal […]
Abstract: The Niangua River-Osage Fork (Gasconade River) drainage divide area in Dallas, Laclede, and Webster Counties, Missouri is the drainage divide between a north-oriented Osage River tributary to the west and a northwest and northeast oriented Gasconade River tributary to the east and was eroded by immense south-oriented floods which were beheaded and reversed by […]
Abstract: The Osage Fork (Gasconade River)-Gasconade River drainage divide area in Laclede, Pulaski, Webster, and Wright Counties, Missouri was eroded by immense south-oriented floods, which flowed across the entire state of Missouri and adjacent states. Flood waters were derived from a rapidly melting North American ice sheet and were captured in sequence from south to […]
Abstract: The Gasconade River-White River drainage divide in Webster, Wright, and Douglas Counties, Missouri consists of an asymmetric west-to-east oriented drainage divide between the south-oriented White River drainage basin and the north-oriented Gasconade River drainage basin and an asymmetric north-to-south oriented drainage divide between east oriented Gasconade River drainage basin and the west-oriented White River drainage […]
Abstract: The Gasconade River-White River drainage divide area in Texas County, Missouri is a north-south oriented drainage divide between the north-oriented Big Piney River drainage basin on the west and the southeast-oriented Current river drainage basin on the east with the south-oriented North Fork White River drainage basin west of the Big Piney River drainage […]
Abstract: The Gasconade River-Big Piney River drainage divide in Laclede, Pulaski, and Texas Counties, Missouri was eroded during a massive reversal of immense south-oriented floods. Flood waters were derived from a rapidly melting North American ice sheet and for a time flowed south across Laclede, Pulaski, and Texas Counties to what was then the newly […]
Abstract: The Osage River-Gasconade River drainage divide area in Osage, Miller, Maries, and Pulaski Counties, Missouri was eroded by immense south oriented floods which were captured and diverted to flow in southeast, east, and northeast directions by headward erosion of deep north-oriented Missouri River and Osage River tributary valleys. Headward erosion of the deep east-oriented Missouri […]
Abstract: The Missouri River-Gasconade River drainage divide in Osage and Gasconade Counties, Missouri is the drainage divide between the northeast and east oriented Missouri River and the Gasconade River, which is a northeast and north-northeast oriented Missouri River tributary.

Abstract: This essay uses topographic map evidence to illustrate and discuss landform origins in the Floyd River-Little Sioux River northern drainage area located in northwest Iowa. A separate essay illustrates and discusses landform origins in the Floyd River-Little Sioux River drainage divide area in Woodbury and Monona Counties. The Floyd River and Little Sioux River […]
Abstract: The Little Sioux River-North Raccoon River drainage divide area in Cherokee, Buena Vista, and Sac Counties, Iowa was eroded during immense south oriented floods from a rapidly melting North American ice sheet. Initially the melt water floods flowed across Cherokee, Buena Vista, and Sac Counties in a southeast direction toward what was then an actively […]
