Great Fire of 1910

All backfiring, trenching and other schemes failed against the determined strength of Mother Nature. A powerful, raging wind blew embers and smokes into a raging inferno near Elk City, Idaho in the afternoon of August 20. Before it was spent, it drove thousands from their homes, decimated Wallace, Idaho as well as burgs and camps on both sides of the Bitterroot Mountains, destroyed as much as $13.5 million in property and approximately 1,280,000 acres of timber and killed 85 people.
