Salt and Gypsum in Alberta

The utilization of natural deposits of salt is one of the oldest industries in Alberta. In 1820, Sir James Richardson visited Salt river, and in the same year D. W. Harmon states chat "clown Slave river, there are several places, where almost any quantity of excellent dean white salt may be taken, with as much ease as sand along the seashore. From these places the greater part of the northwest is supplied with this valuable article". This reference is to the salt chat occurs around springs on Salt river at the northern boundary of the Province. This and other occurrences will be described later in this paper. It is not on account of the development of salt and gypsum in Alberta chat this paper has been prepared, but rather to draw attention to the widespread distribution of salt-bearing and gypsum-bearing rocks, and to the stratigraphic importance of these rocks . The origin of the deposits of salt, gypsum, anhydrite, and dolomite is discussed, and the economic significance of these minerals is considered. There is no salt production reported from Alberta in 1928.
