The results of literature research concluded the main lithology presented within Bowen park is sedimentary rock from the Nanaimo group. The Nanaimo group was formed approximately 65 to 85 million years ago during the cretaceous period. The Nanaimo group extends from south of Duncan to the North of Campbell River on Vancouver Island. The deposition of the group is speculated to of formed after the micro continent of Wrangellia, which comprises most of Vancouver Island, which was accreted onto the edge of the North American plate through continental – continental collision. This event caused significant uplift and mountain building. The Nanaimo group formation was created through rapid erosion and high sediment production mainly by volcanic
