Jackman Flats Provincial Park was established in 2000. At the end of the last ice age, some 11,000 years ago, winds from the main trench of the Fraser River and from, what is now, Kinbasket Lake, deposited vast quantities of sand in the Jackman Flats area. This created an ecosystem considered unique in British Columbia. Rare plant communities and shifting sand dune structures now exist in this rather small park (614 ha).
