Tow Hill

Tow Hill is a large isolated volcanic plug located 21 km (13 mi) east of Masset on the north end of the Naikoon Peninsula of northeast Graham Island in Haida Gwaii, British Columbia, Canada, east of McIntyre Bay and near the mouth of the Hiellen River, which is the site of Hiellen a now-abandoned Haida village and of the Hiellen Indian Reserve No. 2, on the site of that village. Formerly Tow Hill Provincial Park, it is now part of Naikoon Provincial Park, which covers most of the northeastern flatland of Graham Island.

Tow Hill is associated by the editors Canadian Mountain Encyclopedia with the Queen Charlotte Mountains which in turn form part of the Insular Mountains, but it is not physically part of the range, and is separated from mountainous parts of Graham Island by expanses of forested flatland-marsh and is properly designated as being on the Argonaut Plain, one of the lowland areas of Haida Gwaii not in the Queen Charlotte Mountains.

Tow Hill consists of faceted columnar-jointed basalt columns that solidified about two million years ago during the Pleistocene period.
