Cragg Cabin. A reconstructed cabin at Goose Lake Prairie stands as a monument to the pioneer spirit. The original cabin was built by John and Agnes Cragg in the late 1830s near Mazon, 10 miles to the southwest. A predecessor to a truck stop, the Cragg cabin served as a stop on the old Chicago-Bloomington Teamster Trail. The second story - which was added to accommodate the Cragg’s six children, making it one of the first two-story homes in Grundy County - earned the cabin the nickname of “The Palace.”
