Hall, Blake and Associates, Inc. has operated within the Mississippi Embayment since 1978. The Embayment is a bell shaped area that begins in southern Illinois and extends south to encompass the lower Mississippi River Valley. HBA has equipment specifically outfitted to operate within the geologically diverse materials |
