Mattagami River Beach and Aeolian Deposit Provincial Park is a 164 hectare nature reserve approximately 100 kilometres north of Kapuskasing and four kilometres north of Smoky Falls. Ontario Parks lists the park as established in 2003.
The park's official identity is geological and vegetation-focused. Its bedrock lies in the northeast extremity of the Quetico Subprovince, within the Archean Superior Province, and its Quaternary glacial deposits are likely late Wisconsinan in age.
This is a specialized nature reserve for visitors researching northern Ontario surficial geology, glaciomarine deposits, and wetland vegetation. Ontario Parks notes that information on the park's surficial geology is limited, which makes the official landform and vegetation details especially important.
The reserve is dominated by black spruce and black spruce-larch conifer swamps on shallow organic deposits over glaciomarine deltaic sediments. Six significant landform and vegetation representations are known, including dense coniferous forest, mixed mainly deciduous forest, and sparse deciduous forest on glaciomarine deposits.
Wetland representations include open fen, treed bog or conifer swamp, and dense coniferous forest on thin organic deposits covering glaciomarine drift. Ontario Parks says there are no visitor facilities available.
Plan around geology research, glaciomarine deposit study, black spruce swamp awareness, fen and bog observation, vegetation mapping context, low-impact photography, and remote access planning.
Confirm access, maps, no-facility expectations, permitted activities, wetland sensitivity, weather, road conditions, alerts, and park rules through the official Ontario Parks source before travelling.
