The trails are great for hiking but also for those on the lookout for birds or wildlife. New and previously published seismic reflection and shallow resistivity data show discontinuities at the ridge margins in PlioPleistocene strata, yet the timing of most recent faulting and the lateral extent of these faults remain unknown. On Crowley's Ridge, however, the loess continued to collectup to 50 feet deep in some locations! In a study of fishes of Crowley's Ridge, seventeen species were found to exist in streams in or near the RNA. Prevailing winds blow dust into the river fogs. The St. Francis River rises in Missouri and forms a small section of the state line with Arkansas. [1] These loess deposits are a classic example of periglacial loess. Crowleys Ridge, a linearridge trending northsouth for 300+ km through the Mississippi Embayment, has been interpreted as either a faultbounded uplift or a nontectonic erosional remnant.

All the other ridges of the Appalachians are carved from folded . Here, near the end of Crowley's Ridge, it is just above its confluence with the Mississippi just above Helena. 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. 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.
