Yosemite Fire Update for July 18, 2013 (#7)
July 18, 2013
Forbidden (37 45.485 x -119 37.116; 7,400" el., Mariposa CO.) This lightning caused fire continues to moderate in activity and remains at approximately 165 acres. This fire began May 21, when a single tree was struck by lightning. The fire is west of the Eagle Peak Meadow and Creek, a tributary of Yosemite Creek, and is north of Eagle Peak, on the north rim of Yosemite Valley. It is burning through a predominately red fir forest.
The fire is showing minimal activity. The most active part of the perimeter and where smoke is showing the most is to the north east corner. The fire continues to slow as it smolders and creeps through sparse vegetation and other surface fuels in fields of decomposed granite. Periods of increased fire behavior and smoke may increase due to continued warm weather. Sparse fuels might prevent noticeable increases. Parts of the fire have been observed with 6-12 inch flame lengths as it burns through short brush patches and trees.
Although smoke is visible from various locations in the park, including Tioga Rd, Sentinel Dome and Glacier Point, there have been no smoke impacts to Yosemite Valley. Fire managers are working with Mariposa County Air Pollution Control District concerning potential air quality impacts to nearby smoke sensitive areas.
Fire crews utilized natural barriers to check the fire spread to the south on June 10. They last hiked into the fire area July 12, to further monitor the fire for growth, direction of spread, fire behavior and smoke production.
The Forbidden Fire meets the park's fire management objectives of firefighter and the public safety, as the fire presents few risks to values. The fire poses no threat to park service buildings, roads or infrastructure. When appropriate, fire crews will utilize pack stock for logistical support on this fire in an effort to preserve wilderness character.
The fire was named for the Forbidden Wall along the Yosemite Falls trail.
