Abstract

Aerial photographs suggest the presence of numerous sand blows in southern Arkansas but few of the sites have been investigated. Limited work involving trenching, conductivity surveys, and cone penetration tests verify the presence of sand blows in two locations, Ashley County and Desha County. A third location in Lincoln County, called the Phenix site, has received little attention. In the study, ground penetrating radar (GPR) and electrical resistivity survey (ER) have been used to investigate sand blow vents at the Morgan site located in Ashley County and the Phenix site. Nine sand blow vents were detected in total but wet weather conditions diminighed data quality at the Phenix site, illustrating the advantage of conducting surveys under dry conditions. Use of GOR and ER removes most of the guesswork involved in detecting and documenting the presence of sand blows and reduces the time and expense involved in experimental trenching.
