Graham, 10,000 feet altitude, it was found that signals could be flashed to a distance of twenty-five miles during approximately 4.50 hours each day on the average. Two fire lookout stations and a heliograph station are within range. During the past summer three fire alarms were transmitted and one received." (Tombstone Epitaph)
