The site now known as Cranbrook has been seasonally occupied by the Ktunaxa for 10,000 years. This fertile grassland developed in the basin as an ancient glacial lake. It was a productive place with excellent berry crops, good fishing streams, and abundant hunting opportunities. Akisq'aq'li'it name changed to "Joseph's Prairie" after Chief Joseph, who used the prairie extensively in the summer to graze his large herds. Today, Joseph Creek is an intricate and environmentally sensitive spawning creek running through the St. Eugene Golf Resort Casino.
