Yosemite Fire Update #6

July 15, 2015 Posted by: Yosemite Fire Information
New Lightning Caused Fires

Thunderstorms came through the park starting July 1, and remained active through July 11. Yosemite National Park has 9 lightning-caused fires. These kinds of fires can take days or weeks to detect because vegetation has to dry out enough to create smoke or visible flames after the storm passes over. Additional fires may be discovered, as temperatures remain warm and fuels dry out. 

Most of these fires are small;single tree strikes that amount to less than a tenth of an acre. These fires are in the wilderness and are being monitored by either fire crews hiking into the fire areas or via air reconnaissance due to location, sparse fuels, and low growth potential. Yosemite and Point Reyes fire crews are monitoring all fires. 

Blue Jay (37 47.204 x 119 39.183 –Mariposa County, 8,500 feet elevation, 7/7). There is no smoke showing from this fire. 

Dark (37 50.575 x 119 37.153 –Mariposa County, 8,200 feet elevation, 7/ 9). This lightning caused fire is along the Yosemite Creek Campground Rd. Two red fir trees were struck and the surface fuels were ignited. It is at .1 acre and is being monitored.

Clark (37 41.0 x 119 29.6 –Mariposa County, 7,500 feet elevation, 7/9). This is west of Clark Peak. A single tree was seen smoking and it is at .1 acre, with low growth potential. 

Indian Canyon (37 47.532 x 119 35.148 - Mariposa County at 7,200 feet elevation, 7/ 3). This fire is between the Tioga Rd and the Yosemite Valley. It is .5 acre in size, and is smoldering and creeping, with a low rate of spread. It is an area of few recent fires.

Porcupine Flat (37 48.962 x 119 34.416 - Mariposa County, at 8,000 feet elevation, July 3). The top of a single green red fir tree was struck by lightning. There is no ground fire, but smoke may be seen from the Tioga Road. It has low potential for growth.

Fires Declared Out

Others: Gin and East Gin were put out. 

As with all fires, staff and visitor safety is of paramount importance. Each fire, regardless of size, is assessed for the appropriate course of action. At this time there are no road or trail closures and the park remains open. Smoke is staying local over the fires and has not been observed traveling to any smoke sensitive areas. All visitors are urged to use established campgrounds for fires. In all campfires, when departing, please be sure fires are completely out. 

Thank you for your continued interest in Yosemite Fire and Aviation Management.
