Serious erosion problems were addressed recently at the Cakokia Mounds in southern Illinois. Monk's Mound, the largest of the Native American ceremonial mounds at the site, was threatened by severe slumping. Several geosynthetic products were used, in combination with other products and techniques, to deal with these problems. Monk's Mound, built in stages from approximately 900 A. D. through 1200 A. D., has survived to date due to the sound construction techniques employed by its builders. With selective use of modern geosynthetic solutions, the State of Illinois has taken steps to preserve this important site for generations to come. Administered by the Illinois Historic Preservation Agency, the Cakokia Mounds State Historic Site is committed to the preservation and protection of the remaining mounds. A non-woven geotextile was used as a base material for the temporary service road, which provided access to the top of Monk's Mound. Cellular confinement grid was used, in conjunction with crushed gravel, to build the weight bearing service road. Temporary erosion control blankets were used to protect seeded areas and facilitate a strong stand of native vegetation. Permanent turf reinforcement mats were installed to permanently reinforce high flow vegetated diversion channels. Working as a team, the administrators at Cahokia, along with the designers, suppliers and contractors involved, collaborated in an effort to provide solutions to the unique problems associated with this important historic site.
