| | Gabbro erratic by the Trent River, Campbellford, Ontario, Canada |
 | | There are numerous bodies of gabbro and associated rocks in southeast Ontario, including the Lavant mass north of Sharbot Lake, the Raglan Hills east of Bancroft, and several examples between Bancroft and Madoc, near the line of the Old Hastings Road (Easton, 1992; Wilson, 1994). |
 | | The deglaciation of southeast Ontario occurred roughly 12,500 to 11,500 BP (years before present), leaving the detritus of moraine deposits such as the Dummer moraine at around 12,000 BP (Terasmae, 1980). |
