Rocks and minerals from the Bancroft region, including Bancroft, Bedford, Deloro, Eganville, Gooderham, Norland, Madoc, Marmora, Quadesville, Tory Hill, and Wilberforce. Although very few of these were found by me (my first rock and mineral collection is long gone; it was donated to a school for their science class), I have collected at one time or another in all of these regions.
