Jackman Flats Park is a product of ice and wind. 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.
Excellent recreational opportunities such as bird watching and plant identification, have been enjoyed by Robson Valley residents for many years in this special area. The parks most prominent residents are the variety of lichen species that dominate the landscape. The uniqueness of Jackman Flats can be quickly appreciated when one considers that one plant community, Juniperus-Stereocaulon, is found nowhere else in British Columbia.
