Abstract
This report summarizes findings of an Ontario Geological Survey two-year regional-scale, reconnaissance-level mapping program of karst features within Phanerozoic strata of southern Ontario. The 2006 field season focussed on exposed and thin-drift regions proximal to the Niagara Escarpment and younger Devonian cuestas of southwestern Ontario. This physiographic region encompasses the western St. Lawrence Lowlands (Chapman and Putnam 1984; Sanford 1993), including Manitoulin and adjacent islands. This regional-scale survey of karst will incorporate and build upon currently active and past local and regional karst studies in southern Ontario (e.g., Ford 1961, 1974, 1983, 1987; Pluhar and Ford 1970; Ford and Quinlan 1973; Cowell and Ford 1975, 1980, 1983; Cowell and Woerns 1977; Goodchild 1978, 1984; Ford and Williams 1989; D.W. Cowell and Associates, Inc. 1989; Tinkler and Stenson 1992; Cowell et al. 1994a, 1994b; Enyedy-Goldner 1994; Buck 1994a, 1994b, 1999, 2003; Worthington, Ford and Beddows 2000; Worthington 2003; Kunert and Coniglio 2002; Buck, Worthington and Ford 2003; Strynatka 2003; Russell 2004; Abbey, Hurley and Merry 2004). The main purpose of this multi-year karst inventory project is to provide a geological framework and characterization of the physical–chemical responses of the various Paleozoic bedrock units throughout southern Ontario to karstification. It builds upon recent field studies carried out by OGS staff and others, the purposes of which were to assess particular physical characteristics of soils and the nature of jointing within selected thin-drift and exposed limestone plains in southern Ontario (Andjelkovic and Cruden 1999; Strynatka 2003; Russell 2004). The karst inventory project includes 2 field-based components: 1) a two-year karst mapping initiative of south-central and southeastern Ontario (2005) and southwestern Ontario (2006); and 2) a contracted assessment of bedrock character beneath selected thin-drift areas within the various limestone plains of southern Ontario (Brunton, Dodge and Shirota 2005). The subsurface three-dimensional (3D) karst (borehole) study was conducted by Golder Associates during the fall and winter of 2005–2006 and is currently undergoing final preparation. Results of the borehole study will be incorporated into the final karst inventory report and geographic information system (GIS)-based maps, scheduled for release in the spring of 2007.
