Kellogg Biological Station (KBS), Michigan State University's largest off-campus education complex, is located in Ross Township south of Hickory Corners, Michigan (about 65 miles (105 km) from the main campus). Many of the facilities there were originally built by Will Keith Kellogg of Kellogg's cereal, after whom the station is named. KBS includes nearly 16.5 square kilometres of land and, together with nearby state lands and preserves, allows for large-scale studies by biologists. The National Science Foundation has a Long-Term Ecological Research site at KBS.
