Mt Headley was the site of one of Montana’s 639 lookout towers that were built after the huge fire of 1910 that burned three million acres of forest in Washington, Idaho and Montana and which killed 87 people including 78 firefighters. The lookout cabin, built in 1928, was located just behind this sign at the very peak and there is still some debris from it remaining just below the sign. It was a cupola design cabin somewhat similar to the one that still stands onPriscilla Peak.
