In 1975 and 1976, excavations along Victoria Road in Guelph, Ontario exposed a paleosol and overlying fossiliferous sediments between tills. The site records a glacial advance and retreat with associated glaciofluvial outwash (early Wisconsinan or older), a long period of weathering, deposition of organic pond sediments (dated as >45 000 years) containing plants, ostracodes, molluscs, and insects, which indicate a cooler and drier climate than present, and a multiple till sequence probably including Catfish Creek and Port Stanley Tills of late Wisconsinan age (25 000–14 000 years old). The paleosol may be of early middle Wisconsinan age or older.
