Fire Update September 5th, 2017

There are multiple fires burning in Yosemite National Park's wilderness. A high pressure system remains in place with cooler temperatures today and increased cloud cover which will limit smoke dispersion.  Thunderstorms are possible this afternoon into the early evening. Thunderstorms produce gusty and erratic winds.



The Railroad fire is 10,734 acres and 23% contained. Improved overnight humidity recovery aided in continued moderation of fire behavior. The evacuation order of Fish Camp was lifted last night at 8 pm, however Fish Camp may become threatened again from fire approaching from the east. Only residents will be allowed and access must be from the north at Wawona. Highway 41 continues to stay closed from south of Wawona to Sky Ranch Road.  For more information go to Inciweb:https://inciweb.nwcg.gov/incident/5553/


South Fork

Discovered: 8/13/17                           

Location: .75 miles east of the community of Wawona

Size: 7,531 acres        Cause: Unknown        

Containment: 47%      Fuels: Mixed conifer and red fir


Fire remains quiet near the community of Wawona. The most activity yesterday was on the east flank burning into the wilderness through scattered pockets of dense fuel and the south flank backing into the South Fork of the Merced. There was an increase in acreage due to more accurate mapping. Thunderstorms are predicted this afternoon with slightly cooler temperatures and higher relative humidity, producing gusty and erratic winds.


The northern spot fire remains south of handline at Turner meadow. Crews brought fire down to Chilnualna Creek to secure the spot fire with the main fire. Patrols continue along portions of the fire closest to Wawona. There may be some burning well interior and visible smoke with increased winds due to the storms. Bucket work may be continued on the southern boundary of the fire. Both spot fires south of the South Fork of the Merced drainage were contained and secured with hose lays and handlines. Sections of the north flank and the entire east flank are continuing to burn in the wilderness, and will be monitored by aircraft due to steep and rugged terrain. As fire burns into the high country wilderness it will burn actively through pockets of dense vegetation but will then slow down as it progresses into sparse vegetation and natural granite barriers limiting smoke production. This high country wilderness area has minimal values at risk.





Discovered: 8/1/17     

Location: 1 mile east of Yosemite Ski and Snowboard Area and 3/4 mile south of Glacier Point Road

Size: 4,914 acres        Cause: Lightning         

Containment: 55%      Fuels: Red fir             


Fire activity was minimal yesterday. Acreage has increased due to more accurate mapping. Glacier Point Road is scheduled to reopen on Tuesday, September 5, 2017, if favorable conditioned continue. Signage and traffic control will be in place to mitigate smoke and other hazards on the road; there is a potential for implementing temporary road closures or single lane convoys from Bridalveil Camp Ground to Mono Meadow trailhead. Weather forecast for today predicts possible thunderstorms over the wildfire location, which could bring gusty and erratic winds. A cooling trend with increased relative humidity is expected over the next 24 to 48 hours.


Fire crews are implementing a perimeter control strategy for the north, west, and southern flanks of the fire to protect Bridalveil Campground, Yosemite Ski and Snowboard Area, Yosemite West subdivision, Wawona Road (Highway 41), and Glacier Point road. The north, west and south flanks of the fire are contained and holding. Areas of new smoke may be seen as the fire cleans up areas of unburned fuel interior.  Fire management personnel are implementing this strategy on three sides of the fire to minimize further smoke production in heavy fuels. The east flank is being allowed to move towards the Illilouette basin to continue to enhance forest resiliency in a fire adapted ecosystem


Yosemite National Park has managed fire in this wilderness area for decades. This high country wilderness area is very steep and rugged with numerous natural barriers and minimal values at risk.

Size: 3.3 acres                        Cause: Lightning         Spread Potential: Low

Fuels: Lodgepole/Red fir         Strategy: Monitor                


Creeping and smoldering, burning in large logs which are creating smoke.     


Knob 91

Discovered: 8/4/17     

Location 37° 52.185' x W 119° 35.217' at approximately 8980 feet elevation

Size: .39 acres            Cause: Lightning                     Spread Potential: Low

Fuels: Timber litter      Strategy: Monitor                   


A high pressure system remains in place with increased cloud cover form tropical moisture which limits smoke dispersion in the morning and afternoon. Air quality will remain poor close to the fire especially in valleys and drainages. Fire Managers are working with the local Air Quality Districts and will be monitoring smoke impacts to the park and local communities. Community members who are sensitive to smoke may want to close their windows and doors, limit outdoor activity, and monitor the air quality forecast linked below for changes to the forecasted patterns.

No Limits Adventure Camp - Press Release

Yosemite Valley September 5 - 9

Over 30 years ago, Mark Wellman was paralyzed in a climbing accident in the Sierra Mountains but didn’t let it slow down his passin for exploring the mountains and wilderness.  He made the first paraplegic ascents of Half Dome and El Capitan and pioneered techniques for adaptive rock climbing for people with disabilities. Now, he’s sharing that passion by bringing a group of ten people who use wheelchairs on a multi-day adventure camp in Yosemite Valley.  People with spinal cord injuries and other disabilities will get to experience rock climbing on Yosemite’s granite walls, handcycling below Half Dome and Yosemite Falls, and the camaraderie of camping next to the Merced River during the No Limits Adventure Camp in Yosemite.  Many of the campers have never been to Yosemite Valley or experienced rock climbing.


The No Limits Adventure Camp is funded by a grant from the Yosemite Conservancy.  No Limits is partnering with the Yosemite Mountaineering School to provide the climbing activity and BORP Adaptive Sports from the San Francisco Bay Area to provide the cycling activities.


Adaptive Rock Climbing is made possible for people with disabilities through the specialized equipment and techniques developed by Mark Wellman and other climbers.  Traditional climbing equipment such as pulleys, belay devices, and rope ascenders are combined with special seats, harnesses, and grips that allow people with limited leg or arm function to ascend the wall.


Cycling is made possible through handcycles and other bikes designed specifically for people with a wide range of abilities.   In addition to the bikes being powered by arms rather than legs, some have modified brakes and shifters for people with limited hand function as well.


The camp will be based at Yosemite Valley’s Housekeeping Camp.
