Abstract
Oshawa, located centrally along the north shore of Lake Ontario east of Toronto, is mainly situated on the glacial Lake Iroquois sand plain. Ordovician shale and limestone are only exposed along creeks which cut through 10 to 40 m of drift. Multiple-till sequences known from the lake bluffs at Newcastle to the east, together with intercalated sand and clay, span most of Wisconsinan time, but are poorly known at Oshawa. Water-bearing sands and the search for waste disposal sites are leading problems in the area. A major inter-agency project, centred on the Oak Ridges Moraine north of the city, is yielding new surface mapping and subsurface geologic analysis using a comprehensive computerized data base. Computer-generated bedrock topography and drift thickness maps have been produced, as well as subsurface geologic cross-sections.
