St. Leon Hot Springs were first taken up by M.M. Grady of Revelstoke, in 1894. He replaced the first little humble hotel by a handsome big one in 1901. It soon drew a splendid patronage from all over the Kootenays. In the first hard year of the war, Mr. Grady had reluctantly closed the hotel and disconnected the hot-water flow. Not to be denied, Revelstokers begged him to plan a portion of this 320 acres as a townsite where they could erect cottages or camp tents of their own. He did this in 1918, and in a little while 10 nice cottages were built, while others bought lots to camp and later build on. See also St. Leon Hot Springs.
