With increasing positive cases of COVID-19 in the greater Yosemite region, this is to clarify some confusion related to prevention, testing, and vaccinations.

COVID-19 Prevention Recommendations
Getting vaccinated is the best way to protect yourself and your family from COVID-19. COVID impacts different people in very different ways and it is impossible to tell exactly how a specific person will react if they become ill. While vaccinations do not 100% prevent illness, they do provide protection against getting sick and help to greatly reduce serious complications from the illness if you do test positive for COVID.

Most importantly, if you are showing signs of any illness (headache, runny nose, cough, etc.), stay home and either visit Yosemite Medical Clinic or your healthcare provider. Even minor signs of illness can be signs of COVID. Please help prevent the spread of illness in the workplace. Remember to wear a mask and wash your hands frequently with soap and water. These small actions can prevent and reduce the spread of illness.

COVID-19 Testing
In addition to vaccinations, frequent testing is a critical tool to help protect the Yosemite Community. Many people carry the COVID virus but show no signs of illness. Surveillance testing helps to quickly identify anyone who is actively shedding the virus, but not showing any signs of illness. For people with frequent contact with large numbers of the general public or who work in the hospitality and public service sectors, our local Public Health officials recommend getting tested once every 7 to 14 days.

Free COVID-19 testing is available in Yosemite Valley on Mondays and Thursdays for the foreseeable future.
– On Mondays, testing is available by LHI outside of the Yosemite Medical Clinic Building from 10 am to 6 pm.
– On Thursdays, testing is available by LHI at the Curry Village Wellness Center from 10 am to 6 pm.

Walk-Ins are welcome! If you happen to know your LHI patient ID number, please bring that with you to expedite your check-in process. To schedule an appointment, visit please https://www.lhi.care/covidtesting

Yosemite Medical Clinic does perform COVID testing as needed for symptomatic individuals. The Yosemite Medical Clinic is open 6 days a week (Mon-Sat). Patients will be evaluated by a provider to determine if testing is indicated.

COVID-19 Vaccinations
Are you interested in getting vaccinated? Free COVID-19 vaccinations continue to be provided by the Yosemite Medical Clinic on Wednesdays from 9 am to 5 pm. Online registration is required and can be completed in advance on your computer or mobile device or onsite, at https://myturn.ca.gov

Online registration may take up to 10 minutes. Registering in advance is highly recommended. When registering before vaccination day, please select the appropriate clinic and date from the options on the website. If you choose to register on-site, you will be asked to use your mobile device or a provided loaner. Assistance will be available if needed.

Remember to bring photo ID and insurance card (if you have one). Loose-fitting clothing and/or short sleeves are recommended. Please expect the whole process to take approximately 30-40 minutes, including check-in and observation.

Vaccinations available at Yosemite Medical Clinic are for individuals 18 and older. The Moderna and Johnson and Johnson Vaccines are currently available.

The Pfizer vaccine is now available for anyone ages 12. If you are interested in the Pfizer vaccine, free clinics are available through Mariposa County Public Health.

Booster shots are now available for immunocompromised patients. Information about booster shots for the general public will be coming soon.

Continued Algal Testing At Patty’s Hole & Around The Park
Resources Management staff continue to sample Patty’s Hole biweekly for toxic algae. The last test on 8/24 came back negative for cyanotoxins. Additional tests from sites around the park are forthcoming and staff are visually monitoring the park’s main water bodies. Please report any large algal blooms and/or algae that is particularly bright, bubbly, strange-looking, or appears like a haze in the water to Cat Fong at catherine_fong@nps.gov. If you suspect a site has toxic algae, avoid drinking water from the site and recreating in and near the algae. Prevent pets from drinking the water and eating or touching algae in the water and dried on the shore. Additional information concerning harmful algal blooms can be found at https://mywaterquality.ca.gov/habs (C. Fong)



Mist Trail Repair 9/7-11/4
The Lower Mist Trail- from the John Muir Trail (JMT) junction (just uphill from the Vernal Fall Footbridge) to the top of Vernal Fall – will be closed Mondays through Thursdays from September 7 to November 4 between the hours of 630am and 4pm. The trail will remain open on weekends.

The trail is expected to be open overnight, however there may be certain days when trail crew is not able to make it safe to open overnight. In that case, the gates will remain closed, and signs will be posted at the two closure gates that the trail is closed.

Hikers and backpackers headed to Half Dome, Cloud’s Rest, and points beyond from the trailhead at Happy Isles may hike uphill on the Mist Trail if they reach the Mist Trail/JMT junction by 630am, Mon–Thurs. Otherwise, they must hike up the JMT (approx. 1 mile longer).

Mon–Thurs, hikers and backpackers traveling downhill/returning to the trailhead are encouraged to use the JMT to descend at all times since it will not be possible to change the sign at the trail junction at the Nevada Fall restroom anytime the Mist Trail needs to remain closed overnight.

There is a $280 fine for entering a closed construction zone. (W. Weaver)

High Voltage Transmission Line Repairs – El Portal Road Delays
PG&E crews will begin Thursday, August 26, with repairs to the high voltage transmission line between Yosemite View Lodge and the Powerhouse.
hen on Friday, August 27 they will begin with intermittent single lane traffic control with up to 15-minute delays along these 5 miles of the El Portal Road.
Crews will be working Monday through Saturday, 7AM to 5PM.

This project is scheduled to continue through the end of October. The repairs are similar to what you may have seen along California State Route 140, just west of the Park where crews are using helicopters to assist with repairing the existing high voltage towers and replacing the conductors, etc.

Crews will be working Monday – Saturday, so please allow enough time as you along the El Portal Road over the next couple of months. Here are the following delays along the El Portal Road that will continue thru the end of October:
*Monday – Saturday with 15 Minute Delays = 7AM to 5PM
*No Sunday or night work is scheduled at this time. Also, no work around El Portal houses on Saturdays, however there will be other Saturday work.

– Due to safety concerns, the trails, picnic areas, and climbing routes will be closed when crews are working in these areas along the El Portal Road.
– Flight crews will be using the El Portal Sand Pit, an area adjacent to Yosemite View Lodge and an area in Foresta as landing zones, so please understand material and personnel will be flying back and forth between these areas to the transmission line repair areas, so please slow down and be patient.
– The reason crews are working Saturdays is because there is a limited period, they can work in these areas with the goal of completing this work in 2021 before the weather conditions prohibit any further work in this highly treacherous terrain. (M. Pieper)

In case of an emergency or if a community member needs to exit, any vehicles/equipment in the road will be cleared in short amount of time and will not impede travel or emergency response. Flaggers and crew members will communicate with community members and can accommodate any special access requirements as needed. (J. Llewellyn)

Ahwahnee Drive Traffic Delays Through Mid-September
The Historic Preservation Crew is working to restore the Ahwahnee Gatehouse and Gate Post. A one lane closure will result in single lane traffic control on Ahwahnee Drive. The closure will be in place Mondays through Thursdays, 24 hours per day. Traffic will be controlled by temporary stop lights. Wait times are expected to be minimal. This weekly closure is expected to be in place until mid-September. (M. Bablitch)

Black Oak Restoration Through Late Fall
Extending into late fall, Calaveras Healthy Impact Product Solutions (CHIPS) crew composed of local tribal members will be working on restoring California black oak groves in Yosemite Valley, specifically near Yosemite Valley Elementary School. Black oak is a cultural keystone species for the park’s seven affiliated tribes: North Fork Rancheria of Mono Indians of California, Tuolumne Band of Me-Wuk Indians, Picayune Rancheria of the Chukchansi Indians, Kutzadika’a Mono Lake Indian Community, Bridgeport Paiute Indian Colony, Bishop Paiute Tribe and the Southern Sierra Miwuk Nation. Groves in Yosemite Valley were planted, tended, burned and harvested by tribal members for centuries. They were removed from this role to the detriment of cultural traditions and the health of black oaks. Tribal and CHIPS crew members will tend to oaks, plant acorn, and prepare the groves for future prescribed burns. These activities will reestablish relationships with these groves, promote seedling and sapling recruitment and promote high-quality acorn production. This project is made possible through the generous support of Yosemite Conservancy donors. (E. Dickman)
