Geology notes

"Although most of the rocks represent fluviatile deposits, some of the sediments were deposited in slowly moving water; this is indicated not only by the presence of some coals but also by the abundance of Potamogeton and Nymphar" (Wolfe & Tanai, 1980)

Locality notes

"The outcrop at Coal Cove probably yielded the collection of plants described by Heer and attributed to a locality on English Bay. No Tertiary rocks are exposed on English Bay, and the Coal Cove outcrops were mined for coal by Russian vessels." (Wolfe & Tanai, 1980)
