A campsite at Great Glacier was previously a Forest Service Recreation Site before the Provincial Government designated Great Glacier as a Class A provincial park in 2001. Designation followed the recommendations of the Cassiar Iskut-Stikine Land and Resource Management Plan to protect the area in recognition of its scenic river-level glacier and spectacular peri-glacial lake.
Great Glacier Park is located within the asserted traditional territory of the Tahltan First Nation. The Stikine River is still used as a subsistence fishery.
Great Glacier park lies within the Boundary Ranges Ecosection. It projects a variety of low elevation peri-glacial ecosystems, including uncommon plant species and old forest.
