The Schudel No. 2 Site, southeast of Hamburg, Illinois, preserves the remains of a pre-Columbian Middle Woodland habitation area, with some artifacts from other periods as well. Its midden deposits, ceramics, chert fragments, and discarded tools reveal everyday human activity over an extended span of time. The site is also distinguished by unusually dark soil, particularly in areas where artifacts have been found. Because of its archaeological importance in documenting long-term habitation and material culture, it was added to the National Register of Historic Places on June 15, 1979.
