The origin of Crowley's Ridge, northeastern Arkansas: Erosional remnant Roy B. Repeated intervals of erosion and deposition of glacial outwash by the ancestral Mississippi and Ohio Rivers form the Eastern and Western Lowlands and Crowley's Ridge. The only uplifting in the otherwise flat Arkansas Delta, the anomaly rises 150 feet and is just 12 miles across at its widest point. The low-lying areas around the ridge were once much swampier, and the ridge provided a natural and more healthful place for settlers to establish homes. Crowleys Ridge is a unique geological formation in which many cities of the Arkansas Delta region reside. The ridge is surrounded by the fertile lands of the delta region. The New Madrid seismic zone has been the source of multiple major (M ~7.07.5) earthquakes in the past 2 ka, yet the surface expression of recent deformation remains ambiguous. The Forrest L.

The 17-acre site was home to Mississippian Indians from A.D. 1000-1550. We returned briefly to Missouri, and at the Missouri Conservation sign for Chalk Bluff drove another spur west to the flatter Missouri side of the river. When these rivers shifted their courses, Crowley's Ridge was left behind as a long, low, hilly formation.
