Abstract Thirty-three aggregate pits between Cambridge and London are documented. The pits are situated in a variety of landforms (moraines, drumlinized uplands, hummocky terrain, outwash plains), geological map units, and stratigraphic positions. Many have not been documented previously. The objective was to capture a snapshot of the general sedimentary character of as many pits as possible in a four day timeframe. For each pit, a point form summary is provided followed by a general description and photographs that document the facies architecture of the deposits. A summary section provides a brief synthesis of the observations and highlights three key hydrogeological points that can be further understood by study of these deposits. Detailed sedimentological observation in this integrated regional framework provides the opportunity to begin a re-assessment of the underlying conceptual geological models for parts of southern Ontario.
