The sandy and gravelly Glacial Lake Iroquois beach is a remnant of the Wisconsin glaciation. It was deposited by Lake Iroquois, the precursor to
Lake Ontario , about 12,500 year ago. As the lake was shrinking, a line of beach deposits was receding as well, resulting in deposition of sand over the layers of silt and clay that were deposited when the lake was deeper. Following the final recession of the lake, the exposed sand layers were soaked by rainfall. Due to impervious layers underneath, highwater table resulted in formation of large areas ofswamps andmarshes . Eastern parts of the conservation area are occupied by treed swamps andthicket swamps under the power transmission lines, where trees were removed.The western portions of the area are characterized by the steeply incised valley of the Lynde Creek. At places where it cuts across the sandy Lake Iroquois beach,
groundwater seeps occur, providing anecological niche for plants growing on the valley's walls.Cultural history
In the late 19th and early 20th century, a deep
gully , incising the area, was used by horse thieves as alayover . Local inhabitants interpreted the noises produced by the thieves and horses in a superstitious way: they assumed that theDevil was holding court there. Hence, the gully was named Devil's Den.During the 1910s, the
Canadian Northern Railway constructed a new line to provide passenger service fromToronto to Trenton. A bridge over the Devil's Den was completed in March 1910. While the bridge itself has been demolished, remains of cementabutment s and piers that served as a foundation of the bridge can still be found in the area.References
