It was established in the 1890s and improved by the WPA in the 1930s.","why_significant":"The nomination argues the camp is significant under Criterion A for its long role in National Guard marksmanship training and military preparedness in Illinois. It was heavily upgraded by the Works Progress Administration between 1934 and 1937 into a modern pre-World War II range. It was also used by the FBI for firearms training into the early 1970s.","narrative":"Camp Logan was a National Guard rifle range on the Lake Michigan shoreline northeast of Zion, Illinois, now inside Illinois Beach State Park. Established in the 1890s, it grew into a cantonment of barracks, a headquarters, a pump house, a custodian's cottage and a weapons range with targets from 200 to 1,000 yards. Between 1934 and 1937 the Works Progress Administration drained and leveled the marshy grounds, straightened Kellogg Creek, built a road, sidewalk, bridge and fence, and reconfigured the range for newer weaponry. A mess hall was added in 1950 as part of a statewide Guard building program. Besides Guard units, the FBI's Chicago and Milwaukee offices trained there until the early 1970s, and in 1935 the FBI developed its Practical Pistol Course at the range. The camp closed in the early 1970s and much of the range was removed. The district's remaining buildings, structures and site features were recognized for their link to military training in Illinois.","period_of_significance":null,"architect_builder":"Works Progress Administration (WPA) built many 1930s improvements; Illinois National Guard built the 1950 mess hall","architectural_style":"No style","criteria":["A"],"status_note":"Now part of Illinois Beach State Park; the camp closed in the early 1970s, and the surviving buildings serve for maintenance, storage and stabling.
