A 20,000+ hectare area incorporating much of the Cheakamus River watershed has been identified by Squamish Nation as a Wild Spirit Place, called Kwáyatsut. A Wild Spirit Place is an area of cultural, spiritual and/or ecological significance to the Squamish Nation. Further analysis is needed to determine the appropriate designation and boundaries for this area, which is largely within Garibaldi Provincial Park. (Squamish Nation Forest Recreation Guide, 2003). The meaning or significance of the word Kwáyatsut is not provided; pronunciation may approximate kway a sote.
