Mount Sylvester is a large formation of rock of the glacier period found in central portion of the Island of Newfoundland.[1] The mountain lies within the boundary of the Bay du Nord Wilderness Reserve of the province of Newfoundland and Labrador, Canada.
The mount was so named for Sylvester Joe, a native Mi'kmaq of Newfoundland who was engaged by William Cormack to guide him on his trek across Newfoundland. The area which makes up Mount Sylvester is known as an Inselberg, a rock tower produced by chemical weathering and further modified by glaciation.
