Wind Maker is a Blackfoot Under-Water Person — a localized water-spirit rather than a sky deity — said to dwell beneath the head of the Upper St. Mary's Lake. Grinnell records that he has been seen and his form described, and that he raises the wind by making the waves roll. Among the lesser personified powers (Above Persons, Ground Persons, Under Water Persons) he was invoked, with Thunder and Cold Maker, to influence the weather.
