It is estimated that Canada has more than one million billion tonnes of salt, or halite, as it is called in geological terms, in three major rock formations. In western Canada, salt beds underlie a broad belt of the Prairie provinces extending from the extreme southwestern comer of Manitoba northwestward across Saskatchewan and into the north-central part of Alberta. Depths vary from 180 metres in at Fort McMurray to more than 1830 metres around Edmonton. The deposits, overlain with different rock types, are commonly 2 in to 3 metres in thick, but this varies.
