Fire Update September 12th, 2017

There are multiple fires burning in Yosemite National Park's wilderness. Showers and thunderstorms are possible each afternoon and evening through Thursday with increased relative humidity and cooler temperatures. Gusty and erratic winds are possible with any thunderstorm that develops.


Yesterday smoke was good to moderate throughout the Yosemite area for most of the day. Dispersion remains poor today and tomorrow, however most areas are likely to stay in the good to moderate range unless there is new fire activity. The fire area received substantial wetting rain yesterday and activity should be minimal under continued high humidity and light winds. 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. 







The Railroad Fire is 12,407 acres and 80% contained. Thunderstorms brought about a quarter of an inch of rain last night, today crews will continue mop up operations to extinguish hot spots near the perimeter. For more information go to  https://inciweb.nwcg.gov/incident/5553/


South Fork

Discovered: 8/13/17                           

Location: .75 miles east of the community of Wawona

Size: 6,840 acres        Cause: Unknown        

Containment: 47%      Fuels: Mixed conifer and red fir


Fire remains quiet near the community of Wawona on the west and south flank of the fire. Sections of the north flank and the entire east flank are continuing to burn in the wilderness. For more information go to Inciweb: https://inciweb.nwcg.gov/incident/5502/



Discovered: 8/1/17     Location: 1 mile east of Yosemite Ski and Snowboard Area and 3/4 mile south of Glacier Point Road

Size: 6,000 acres        Cause: Lightning         

Containment: 55%      Fuels: Red fir 


Fire activity was minimal yesterday due to increased cloud cover and precipitation. Fire crews implemented a strategic burning operation along Glacier Point road from Mono Meadow Trailhead towards Horizon Ski trail. Glacier Point Road remains closed until further notice due to fire operations. For more information go to https://inciweb.nwcg.gov/incident/5475/

Fuels: Red fir/ Lodgepole        Strategy: Monitor                   


Fire personnel have secured the northern edge of the fire which will prevent fire from entering steep slopes down into Little Yosemite Valley. Fire continues to back towards the Cascade Cliff area. Smoke will be visible from the high country.



Discovered: 9/7/17

Location: Hwy 120/Big Oak Flat Rd. at Foresta Rd.

Size: 15 ac.                 Cause: RV/ Vehicle fire   

Containment: 100%       Fuels: Grass mixed shrubs


The fire started due to an RV catching fire and spreading north into the old Big Meadow burn scar which helped limit its spread.  Yosemite fire crews will be checking this fire.

Yosemite Forum Monday, September 18 (Note Special Date)

"A snow hydrologist's apology: Demystifying Sierra snow and ice with the NASA Airborne Snow Observatory" by Dr. Thomas Painter, NASA


The NASA Airborne Snow Observatory (ASO) has revolutionized how we characterize Sierra Nevada snowpack and mountain glaciers, in a way sadly laying waste to our mythical understandings of this most critical resource and landscape. Prior to the ASO, we largely understood snowpack and glacier dynamics from what we could see or measure on skis or foot, with the federal sampler, a depth probe, a GPS unit, a tape measure, wood stakes, a stone, horse-hair, and a load of Scottish chutzpah. Now, putting assumptions behind us that have led to unverifiable myths, the ASO allows us to finally quantify Yosemite’s snow water equivalent, snow reflectivity, snow grain size, dust and black carbon enhancement of sunlight absorption, glacier volume changes, snow algae concentrations, periglacial forms, ecosystem function, and controls on snow versus glacier melt contributions to runoff. My sincerest apologies … look away if you want to keep the mystery!


The Forum will take place Monday, September 18, from 3:30 to 4:30 pm in the Yosemite Valley Auditorium.  Please contact Greg Stock at 379-1420 for additional information.  (G. Stock)



Power Outage September 18-22

PG&E is scheduling a power outage beginning Monday September 18 through Friday, September 22nd. (Possibly adding dates 9/17 and 9/23)


Arch Rock and El Portal will not be affected by this outage. 


Glacier Point, Wawona Tunnel and Yosemite Valley will be provided with electrical generation during this time, but expect to have some delays, power bumps and/or minimal outages. 


Big Oak Flat Tunnels will not have back up generation during this outage.


NPS High Voltage is working directly with PG&E to minimize impacts to Yosemite.  (K. Bablitch)



​ZLF Facelift Booth September 26 to October 1

Volunteers are needed to help staff Yosemite's Zero Landfill Initiative booth at the park's Facelift event​. ​Once Facelift begins accepting volunteers on September 27, the booth will be open from 9:00 am to 3:00 pm daily. ​


The booth is made from materials salvaged from the park, so some assembly is required. Construction will start on the morning of September 26. We are also looking for help with tearing the booth down beginning at 3:00 pm on Sunday, October 1. Volunteers are needed  to help with both construction and tear down. If interested please contact jodi_bailey@nps.gov.  You can also sign up via this spreadsheet: https://docs.google.com/a/doi.gov/spreadsheets/d/1TTNxYfWNIo8xIqQz6jeHibXsnu_fQUpvEoueBvZWo1g/edit?usp=sharing (J. Bailey)​

Glacier Point Road Closure - Empire Fire

The Glacier Point Road will remain closed to the public this week as fire crews conduct backfiring operations along the roadway between Ostrander Lake and Mono Meadow Trailheads. Depending on how these operations go, crews will re-assess conditions on Friday and make further determinations on the road closure at that time. The road is still open to Admin Traffic Only.  (E. Scott)



Tenaya Road Closure September 13-23

Tenaya road will be closed between the Valley Fort and the Courthouse from 9/13/17 through 9/23/17. This is for generator staging for the upcoming valley power outage in Yosemite Valley. Courthouse access will not be affected.  (J. Brown)



Yosemite Valley Parking and Road Construction Update

A new phase of parking and road construction in Yosemite Valley will be starting on Monday, September 18th. The biggest project will be reconstruction of the Camp 4 parking area. The parking area will close on Monday, September 18th and campers will park across the street at the Yosemite Falls parking area. Northside Drive between the Yosemite Falls crossing and Camp 4 will narrow to one westbound lane. Eastbound traffic will travel through Yosemite Lodge. The contractors hope to complete this work by Thanksgiving if the weather is good. If not, the parking area and roads will be open for the holidays.


In addition, new construction will begin on Tuesday, September 19th at the four-way intersection at Half Dome Village near Stoneman Bridge. Flaggers will route traffic headed to Half Dome Village in a one-way clockwise loop going eastbound on the Happy Isle Loop Rd then coming back northbound on Curry Village Dr. This work should take about two weeks.


Work on Northside Drive east of Pohono Bridge is almost complete. Contractors will work on utility vaults in Northside Drive for one week starting Monday, September 18th. This work will take place during the day with one lane open. There will be maximum 30-minute delays.


Lastly, night work will continue at “the Narrows” through September (same schedule as earlier in the month) and work on the pedestrian pathway from the Yosemite Village parking area to Yosemite Village will continue through Monday, September 18th. Thank you for your patience.  (L. Acree)
