Trail section near start point of the blaze. This location is just west, or left, of the flames shown in the earlier picture. Note point above the trail where the unburned brush ends and the burned area begins.
Photo clearly depicts start point of the fire. Smoke along the lower horizontal area to the right of the flames outlines the trail. Flames indicate the far west (left) edge of the fire perimeter. Investigators are looking at the 100 yard section of the trail immediately to the right of the flames as the point where the fire started.
