Other Information

The reserve was created in the late 1980s as part of the Wildlife ’87 project [1] and is the province’s largest Ecological Reserve. It contains part of Alberta’s largest active sand dune system stretching approximately 8 km from north to south and 1.5 km wide.

The active dunes are a series of sand ridges. They are slowly migrating southeast, burying jack pine forests and filling small lakes. There are large areas of kame and kettle. The kames, over 60 metres high, are among the largest in the world. Peatlands range from relatively dry bogs dominated by jack pine, black spruce, Labrador tea and reindeer lichen to wetter peatlands with black spruce, tamarack and peat moss. Shoreline areas include mixed forests of aspen, balsam poplar and white spruce.

Arctic terns, not known to nest elsewhere in Alberta, nest in the reserve. Total wildlife species and populations are not extensive, as a result of the lack of habitat diversity; Red Squirrels are very common, and Beaver, Muskrat, Black Bear, Red Fox, Lynx, Wolf, Moose and Mink are known to frequent the area.

WHERE DID THE SAND COME FROM? The dunes are approximately 8,000 years old and their origin can be traced back to the last ice age and the granite, gneiss, and sandstone bedrocks. The glaciers eroded these rocks on their advance and then torrents of water solidified the fields upon the glaciers’ retreat. As the lakes drained, the sands dried and accumulated into the present dunes. The dunes advance about 1.5 m each year. Any vegetation that stabilizes the sand is often destroyed in the all-too- common wildfires in the area. It is speculated that the dunes will only advance as far as the Maybelle River [2].

WHAT IS A KAME OR KETTLE? Kame and kettle topography are typically found together. Kames are mounds where till is deposited and kettles are depressions formed by ice being trapped under till and then melting. Together, they form a hump and depression landscape often containing many lakes [3].
