The following description comes from the "Biodiversity Explorer", maintained by the Natural Heritage Information Centre in Peterborough
The 12-ha Carson Lake Provincial Park is forested by stands of poplar, white pine and red pine. The park is situated within the Ontario segment of the Grenville structural provinces. The rocks here are of Middle Precambrian age. The park is situated in Site District 5E-11. This area contains lake(s) designated for lake trout management.
The park is a small holding located in an extensive area of strongly broken deep to shallow sandy till uplands with numerous bedrock exposures. [Noble 1984] Because of its small size and the fact that it is completely covered by development this holding has little representational value. [Noble 1984]
