On July 8th, 2008, Yosemite National Park experienced an afternoon thunderstorm, a common occurrence for the Sierra Nevada Range. Another fire was found yesterday afternoon, which brings the total to six fires found since Tuesday’s storm.

Fire is a natural ecological process in Yosemite and each year lightning strikes result in wildland fires that help shape Yosemite’s wilderness. The current wilderness fires are smoldering and burning in a designated zone for Fire Use for Resource Benefit. Naturally occurring fires in these areas are normally managed to allow the fire to clean and shape the forest and its natural landscape. Dead and down trees and other forest litter are burned, opening forest canopy’s which allows sunlight through. This allows for sprouting and regrowth of plants, shrubs and trees. Fire allows for the recycling of nutrients into the soil. This naturally thinning process also helps prevents large stand (tree) replacement crown fires. All of these fires are burning in pervious Fire Use areas. The fire mosaics, irregular burn patterns from the previous fires, have slowed the spread and progress of these fires. This is a desired effect and another reason for managed natural fires.

Hill (7825’) - This lightning caused fire was found at 12:30 on Thursday, July 10. It is S/E of Boundary Peak and west of Yosemite Creek in Mariposa Co. Smoke was seen easily from the Glacier Point area yesterday afternoon. This fire is being suppressed with 35 firefighters on scene.

On July 8th, 2008, Yosemite National Park experienced an afternoon thunderstorm, a common occurrence for the Sierra Nevada Range. That storm resulted in five known lightning caused fires in remote areas of the Park.

Mt Star King (8500’) – This fire is located near the top of Mt Star King and at the edge of the ’91 Illilouette fire, south of Glacier and Washburn points and in Mariposa Co. This is a single tree lightning strike, burning in brush and other dead and down trees. A three person fire crew is spiked out (camped) at the scene and began suppression efforts July 9th. It is 1/8 of an acre in size, and had moderate potential for growth. Smoke may be seen from Washburn and Glacier points.

Pack, Fork and Clark (7000’) – These three single tree strike fires are located near the confluence of the Clark and Illilouette Creeks, in Mariposa Co. A four person fire crew is suppressing this fire. It has little potential for growth.

Cascade (7600’) – This fire is east of the Tioga Rd and near the South Fork of the Tuolumne River, near the top of the Cascade Creek watershed. It is in Mariposa Co and ½ mi south of Tuolumne Co. A three person fire crew is on scene and suppressing this fire. It has little potential for growth.

All of these fires are burning in pervious Fire Use areas. The fire mosaics, irregular burn patterns from the previous fires, have slowed the spread and progress of these fires. This is a desired effect and another reason for managed natural fires.

The Yosemite fire crews are being augmented on the various fires by fire line qualified, Park protection rangers. The weather predictions indicate continued high temperatures and potential afternoon thunderstorms throughout the weekend. It is possible that more lightning caused fires could occur throughout the region.
