—3-D Map of the north side of the Mountain fire, at 10 p.m., July 19, 2013, looking north. The pink line was the perimeter at 10 p.m. Friday, and the red line was 24 hours before that.
The Mountain Fire continued to spread to the north Friday, coming closer to the highest point in the area, Mt. San Jacinto, and within 0.7 mile of the Palm Springs Aerial Tramway
. The 3-D map above which shows the north portion of the fire illustrates the very steep slopes the firefighters have as their work environment. The fire spread very slowly on the south side, while the east and west sides were relatively quiet Friday.
