We are a college committed to a continual emphasis on the integration of scholarship, critical thinking, service, and the spiritual dimension of life. The 200-mile long ridge, of rolling hills rising to 250 feet over the flat Delta surrounding it, is an island of sorts, shaped 50 million years ago by the powerful ancestors of the Ohio and Mississippi rivers, as glaciers moved around the continent. On to historic Helena, where ridge and parkway end. The ridge is capped by a deep layer of wind-deposited (loessial) soils, a fine-grained soil created millions of years ago as glaciers moved across the continent. The unusual formation rises high above the alluvial plain of the Mississippi embayment, ranging from 250 to 550 feet depending on the precise location. It isn't a separately designated route, but a cobble of sections of numerous roads, made a State Scenic Byway in 1997 and National Scenic Byway the following year.

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. Department of Geological Sciences University of Memphis. 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. Native log and stone structures, constructed by the Civilian Conservation Corps (CCC) in the 1930s, set the tone for this parks rustic quality. Phone: +1 314-808-1870 A marked spur just inside Arkansas leads a couple of miles west to Chalk Bluff Battlefield Park on the St. Francis, our first stop.

Please call the park about our dog-friendly cabin. The geography of Crowley's Ridge isolated it like an island. This decrease in gradient and tectonic activity along the New Madrid seismic zone may have caused the eastward shift of the Mississippi River, culminating in the cutting of the present channel through the divide at Thebes Gap. Paramore and Jay Gould, who laid tracks that crossed here, it's believed to be the only "Paragould" anywhere. The ridge is actually an island formed by ancient paths of the Mississippi and Ohio Rivers. Crowley's Ridge and the Mississippi Alluvial Plain, but as the rivers continued to wander and erode, the loess was washed away from the plain. Crowley's Ridge is a geological formation that rises 250 to 550 feet above the alluvial plain of the Mississippi embankment in a 150-mile line from southeastern Missouri to the Mississippi near Helena, Arkansas.

Atop the forested hills in Northeast Arkansas, Crowleys Ridge State Park is situated on a unique geological formation and has a rich history. Fifteen high-resolution seismic reflection lines were acquired across and adjacent to the margins of Crowley's Ridge to test the hypothesis that Corwley's Ridge is fault bounded. Crowleys Ridge extends for 200 miles from southern Missouri south through eastern Arkansas to Helena-West Helena. 1). Crowley's Ridge, a geographical anomaly, divides the eastern part of Arkansas, running from the boothill of Missouri to Helena in the Lower Delta.

This imaginary line divides resistant sedimentary Paleozoic rocks of the Interior Highlands from unconsolidated sediments of the Gulf Coastal Plain. The geomorphology of Crowley's Ridge, apparent Quaternary reactivation of the ridge-bounding faults, and orientation of the faults to the present stress field suggest that the faults bounding Crowley's Ridge and the western margin of the Reelfoot rift may be seismogenic. The Forrest L. Wood Crowleys Ridge Nature Center also features trails outside the facility that take visitors through wetlands, forests, and prairie.
