The following historical information was written and provided by the Ottawa Gatineau Geo Heritage.
"This is Ottawa's only inland sand dune complex— the Pinhey sand dune complex. It has survived with minor modification for over 10,000 years, developed on an old shoreline of the Champlain Sea that inundated the region during the waning stages of the last ice age. This unique ecosystem is home to a number of plant and animal species that can only live in well-drained, open areas with exposed fine-grained sand. Like other sand dunes across North America, it was rapidly disappearing due to a lack of understanding of the biodiversity value of this important ecosystem. In 2011, Biodiversity Conservancy took on the huge project of restoration and reclamation of the Pinhey sand dunes, with the help of the Trillium Foundation, the City of Ottawa and the NCC."
