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)

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 Next Week

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, 2017

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.

Fire Update September 10th, 2017

There are multiple fires burning in Yosemite National Park's wilderness. Showers and thunderstorms are possible each afternoon and evening through Tuesday, with a slight increase in temperature and lower relative humidities. Gusty and erratic winds are possible with any thunderstorm that develops.

 

Railroad

​The Railroad Fire burning in the Sierra National Forest is ​12,358 acres and 70% contained. Highway 41 re-opened September 9th to the public at 2 pm. For the most up-to-date information go to https://inciweb.nwcg.gov/incident/5553/

 

Rattlesnake

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.

 

South Fork

Discovered: 8/13/17                           

Location: .75 miles east of the community of Wawona

Size: 6,740 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 backing through scattered pockets of dense fuel, towards Johnson Creek.

 

The northern spot fire near Turner Meadow has burned into the main fire. There may be some burning well interior and visible smoke with increased winds due to the storms. Both spot fires south of the South Fork of the Merced drainage were contained and secured with hose lays and handline. Sections of the north flank and the entire east flank are continuing to burn in the wilderness. The fire will be monitored by aircraft and fire lookouts. 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.

 

Empire

Discovered: 8/1/17     

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

Size: 5,787 acres        Cause: Lightning         

Containment: 55%      Fuels: Red fir             

 

Fire activity was moderated yesterday due to spotty precipitation over the fire area. The most activity was on the north east section near Glacier Point Road. Glacier Point Road remains closed until further notice due to fire operations.

 

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. Today crews will continue preparation along Glacier Point road from Bridalveil Campground to Mono Meadow trail head and begin implementation of strategic burning operations which will minimize high fire behavior along the road. The west and south flanks of the fire are contained, holding, and will continue to be monitored by aircraft and fire personnel.  Areas of new smoke may be seen as the fire cleans up areas of unburned fuel interior.  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.

 

Starr King

Discovered: 8/2/17     

Location: N 37° 42.965' x W 119° 29.588' at approximately 7800 feet elevation

Size: 60 acres             Cause: Lightning         Spread Potential: Low/ Moderate

Fuels: Red fir/ Lodgepole        Strategy: Monitor                   

 

Fire personnel are on scene and will be securing 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.

 

Yosemite Creek

Discovered: 8/3/17     

Location: N 37° 50.414' x W 119° 38.088' at approximately 7,970 feet elevation

Size: 4 acres   Cause: Lightning                     Spread Potential: Low

Fuels: Red fir              Strategy: Monitor                   

 

Fire is creeping and smoldering and will continue to be checked by fire crews. Fire has received some precipitation over the last few days.

 

Porcupine

Discovered: 8/2/17     

Location: N 37° 49.336' x W 119° 34.720' at approximately 8154 feet elevation off Tioga road.  

Size: 4.8 acres                        Cause: Lightning         Spread Potential: Low

Fuels: Lodgepole/Red fir         Strategy: Monitor                   

 

Fires edge is 30 feet from the Tioga road and is creeping and smoldering and to be checked by fire crews. Fire has received some precipitation over the last few days.

 

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                   

 

Air quality continues to improve throughout the Yosemite area. Winds from a more easterly direction and potential rain from afternoon thunderstorms tonight should keep the remaining Railroad Fire emissions out of Yosemite. This wind direction also makes more direct impacts in El Portal, Wawona, and Yosemite West from the South Fork and Empire Fire possible, but likely transient and dependent on the day’s fire activity. 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.

CONSTRUCTION & TRAFFIC DELAYS

 

Ongoing construction projects or other longer-term events that might impact travel (e.g.

prescribed fires) will be moved here from “New and Happening Today” instead of to “Recent

News.” These items will remain as long as the event is ongoing and will therefore not be

cleaned out at the end of each week like “Recent News.”
