[edit] History

Designated as the Illini and Shawnee Purchase Units. President Franklin D. Roosevelt declared these purchase units to be the Shawnee National Forest in September 1939.

Most of the land obtained for the Forest in its first decade of existence was exhausted farmland. Throughout the 1930s and 1940s, the Civilian Conservation Corps planted pine trees to prevent erosion and help rebuild the soil. However, the Forest is also home to many hardwood trees and other plant and animal species characteristic of the region.

In the 1980s and 1990s, there was an active history of conservation and protest efforts by local, regional, and national environmental groups and individuals ranging from radical movements such as Earth First! to mainstream organizations such as the Sierra Club and the Green Party. The wise use movement once played an active role in lobbying for its vision of the Shawnee National Forest. Today a more cooperative atmosphere has developed, although some controversy remains with a few.

In 2006, the Forest Service completed the development of a new Forest Management Plan for the Shawnee National Forest. This plan, adopted every 10-15 years, outlines the policies and practices of the U.S. Forest Service in overseeing the management of the Shawnee National Forest. The 2006 Forest Plan was completed in collaboration with many environmental and public groups and is designed to maintain and enhance the forest's unique biodiversity.

[edit] Glacial geology

During the Illinoian Stage (between 352,000 to 132,000 years ago), the Laurentide ice sheet covered up to 85 percent of Illinois. The southern margin of this ice sheet was located within what is now the area of the Shawnee National Forest. There are many points of interest marking the southern edge of the glacier. Some are located within the Forest boundary, others are on public land in proximity.

Little Grand Canyon is located within the Shawnee National Forest. This is accessible off Illinois Route 127 south of Murphysboro, Illinois. A small creek with a tiny watershed has carved an impressive rock canyon, more than 200 feet deep, leading down to the Big Muddy River. The southern edge of the ice sheet was just to the north of Little Grand Canyon. Blocks of ice slid off the face of the glacier, carried by enormous volumes of meltwater, to carve this tiny canyon. In the deep shade of the canyon are relictual species of Arctic plants left over from its ancient origin.

Cedar Lake is an artificial lake formed by damming Cedar Creek. The lake is accessible off Illinois Route 127, south of Murphysboro, and off U.S. 51, south of Carbondale. In this area, the Illinoian Glacier climbed the Shawnee Hills at its southern margin. The glacier blocked the waterways flowing north down the hills. This drainage formed a creek running northwest along the face of the glacier. This became Cedar Creek, the watershed of which is extremely asymmetrical. While the watershed extends only a few thousand feet to the south, up the face of the terminal moraine, the creek is also fed by waterways extending miles to the south.
