During the Depression years, under the New Deal program, President Franklin D. Roosevelt established the Emergency Conservation Work program, later known as the Civilian Conservation Corps or CCC, to employ people in large public works projects. In 1934, two CCC camps, BR-9, Company 844, and BR-10, Company 1858, were established at Guernsey State Park, and work began on improvements for the facility. Construction included roadways, foot trails, picnic areas, drinking fountains, fireplaces, a boat pier, a swimming float, a lookout tower, and a museum. Camp BR-10 was disbanded at the close of December 1935, while the remaining camp functioned until August 7, 1938. Numerous structures and other landscape work were completed before this camp was abandoned. An extensive network of trail was originally planned and partially built during the operation of the CCC camp, and ever since that time hiking and trail use has been a major feature at Guernsey State Park.
