Yosemite National Park Announces Pilot Program for Horsetail Fall Event February 12-26, 2018 - Yosemite News Release February 1, 2018  

New program to improve visitor experience and reduce traffic congestion


Yosemite National Park announces a new program for the Horsetail Fall event taking place from February 12-26, 2018. This program has been created to improve the overall visitor experience to view the natural Horsetail Fall phenomenon that occurs each year in mid-February when the sun’s light at sunset causes the waterfall on El Capitan to glow like it is on fire.


Over the past several years, the popularity of viewing the Horsetail Fall phenomenon has grown significantly with thousands of visitors coming to the park to experience this unique event. Growth in the popularity of viewing Horsetail Fall has contributed to major traffic jams with over 1000 vehicles at one time and has created significant safety issues between pedestrians and motorists.


Based on visitor feedback on traffic and concerns over pedestrian safety, Yosemite National Park is trying a new approach to managing traffic for the Horsetail Fall phenomenon. This year, Yosemite National Park is working in partnership with The Ansel Adams Gallery, Yosemite Conservancy, and Yosemite Hospitality to ensure public access and manage vehicles in the viewing area.


During the event, Yosemite National Park is creating an event zone inside Yosemite Valley, from the Yosemite Valley Lodge to El Capitan Crossover. Visitors will be able to enter the event zone and view Horsetail Fall by walking from El Capitan Meadow or the Yosemite Falls Parking Area, taking a naturalist-guided tour, or picking up a permit to park inside the event zone. Within the event zone, the right-hand lane of the road will be converted to event parking for 300 vehicles. To park within the event zone, free parking permits will be required. 250 free permits will be available through online reservations and 50 permits will be issued on a first come, first served basis each day.


Free parking reservations for each day of the event will be available online, beginning on Saturday February 3, 2018 at 9:00 am PST. To book a parking reservation, visit https://2018horsetailfall.eventbrite.com/. 250 parking reservations (a parking reservation is good for a carload of passengers) will be available for each day of the event through EventBrite. 50 first come, first served permits will be available each day from 9:00 am to 3:00 pm at The Ansel Adams Gallery in Yosemite Village.


All online reservation holders will need to bring a printed copy of their reservation confirmation in person to The Ansel Adams Gallery between 9:00 am to 3:00 pm to pick up their vehicle Parking Permit for the event on the day of the reservation. Any permits not picked up by 3:00 pm will be forfeited.


Important Tips for Planning Your Visit to the Horsetail Fall Event:


-  Visitors interested in walking to the event site are encouraged to park in the Yosemite Falls Day Parking Area, park at El Capitan Meadow, or ride the free park shuttle to Shuttle Stop #7 and walk into the event site approximately 1.2 miles one way.


- Yosemite Hospitality, Inc., the park’s primary concessioner, will be offering naturalist-guided tours each day for a fee to the Horsetail Fall Event. To learn more please visit https://www.travelyosemite.com/.


- To reduce traffic congestion in the event zone and to ensure easy visitor access to Yosemite Valley, the park will convert Southside Drive to two-way traffic from El Capitan Crossover to Sentinel Bridge. No roadside parking will be permitted while two-way traffic is in place for the safety of both pedestrians and motorists.


- On Northside Drive, the left-hand traffic lane in the event zone will remain open as an exit route for YARTS buses, commercial buses, and other vehicles exceeding 25’ in length.


 - Visitors who plan to get to Yosemite Valley using the Yosemite Area Regional Transit System (YARTS) should review the YARTS schedule at www.yarts.com to make sure that you do not miss the last bus of the day. The closest YARTS stop to the event is located at Yosemite Valley Lodge. YARTS buses will not be picking up visitors in the event zone.


“The Horsetail Fall Event Pilot Program is one of the many initiatives Yosemite National Park is piloting to address traffic congestion and visitor safety in the park,” stated Acting Superintendent Chip Jenkins. “We are continuously working to test new strategies to provide a quality experience for visitors to Yosemite National Park.”


This Pilot Program is part of a year-round effort to evaluate traffic and parking management to improve the visitor experience. After the Pilot Program for Horsetail Fall is completed this year, the park will evaluate its effectiveness and make adjustments for coming years.

Tuolumne Meadows Winter Conditions Update for January 31, 2018



New snow: 9 inches

Total settled snow depth: 12 inches (at 8,600 feet)

High temperature: 54°F (January 29)

Low temperature:  -5°F (January 26)


Ski Conditions and Weather: While doing the first snow surveys of the season this week we had a chance to see what this winter has amounted to thus far throughout our patrol area. The good news is that we were able to keep our skis on (no walking) for the 50 mile journey. The bad news is that the snowpack is woefully lean for this time of year, and we are in the midst of a warm spell that is seeing more water withdrawals from the Sierra Nevada snow bank daily. Snow depths at the snow courses averaged from 13 ½ inches at Tenaya Lake (8,150 feet) up to 36 inches at Rafferty Meadow (9,400 feet). The water content of the snow was also quite low. 


Presently the ski conditions are good for touring along the Tioga Road, in drainages, and area meadows. Good powder snow still exists above 9,200 feet on north aspects for making turns.  South aspects are mostly bare and east and west aspects are a grab bag of sun and wind affected snow and bare ground. In general, it is spring skiing in June-uary out there folks!


Avalanche and Snowpack Conditions: Avalanche and Snowpack Conditions: Please refer to the Eastern Sierra Avalanche Center (ESAC) for the avalanche advisory for this part of the Sierra Nevada.


The avalanche hazard in the Tuolumne area is currently low. Warm temperatures have helped to stabilize the snowpack following the last snowfall. Prior to, and just after, the 9 inches of snow that fell on January 24 there was a period of high SW winds that formed wind slabs on lee slopes. These wind slabs were touchy and easily triggered. We observed several small pockets of wind slab that avalanched during this wind event especially in areas where there was icy snow remaining from last winter.  


Wildlife: The usual suspects were out and about this week. Coyote and pine marten seemed more active and curious, and less afraid as we skied nearby. With these warm temperatures, perhaps, they are confusing us with the summer visitors who inappropriately “drop” their food more often. Large flocks of dark-eyed juncos followed us along the shores of Tenaya Lake which has yet to freeze solid this winter.


Questions: The Tuolumne Meadows Ski Hut is open. There is firewood and 8 bunks that are available on a first-come, first-served basis. There is no phone service in Tuolumne Meadows at this time. We can be contacted via email, but we may be delayed in responding if we are on patrol. Contact the wilderness office at 209/372-0740 with any questions or concerns. Come prepared, and please make good decisions while traveling in the wilderness this winter. Follow our blog: https://www.nps.gov/yose/blogs/tmconditions.htm. Don't forget the sunscreen!

Yosemite Rockfall Year in Review:  2017

There many large and consequential rockfalls in Yosemite in 2017, with a record 85 events (including rockfalls, rockslides, and debris flows) documented. The cumulative volume of these events was about 36,800 cubic meters. Although this is not the largest annual volume recorded, greater volumes in previous years were typically dominated by one very large event (for example, the 46,700 cubic meter rockfall from Ahwiyah Point in 2009), whereas the cumulative volume for 2017 resulted from several large and medium-sized rockfalls. 


The largest event in 2017 almost escaped notice. On the stormy morning of January 12, road crews encountered downed trees and a damaged manhole on the road between Pohono Bridge and the Big Oak Flat Road junction. They also noticed a suspiciously fresh-looking boulder in the Merced River. Subsequent investigation revealed that the boulder was part of a very large rockslide that originated far above the road in an area known (appropriately) as “The Rockslides”. The total volume of this slide was about 20,000 cubic meters (almost 60,000 tons), most of which was scattered throughout the forested slopes above the road. If not for the single boulder that hit the road, this rockslide might have escaped notice for some time.


Much greater road damage occurred on June 12, when about 650 cubic meters (nearly 2,000 tons) of rock fell from “Parkline Slab”, a sloping cliff just east of the park boundary near El Portal. About one-third of the rock debris landed on the El Portal Road, burying a 60 meter (200 foot)-long section of road under tons of rock; fortunately, there were no cars directly under this area, despite the rockfall occurring around noon during the busy summer season. The road was closed for five days as crews cleared debris and repaired the roadbed. Much loose debris remains on the slope above the road, and could continue to slide during intense rainstorms.


The year’s most consequential rockfalls occurred from the southeast face of El Capitan in September. The first of these occurred at 1:52 pm on September 27, when 290 cubic meters (860 tons) of rock fell from the cliff near the path of Horsetail Fall. Two rock climbers were walking along the base of the cliff directly under the area, and, sadly, one of them was killed and the other seriously injured. YOSAR quickly extracted both climbers, as several more rockfalls totaling 163 cubic meters (440 tons) pummeled the base of the cliff over the next few hours. At 3:21 pm the following day (September 28), a much larger rockfall occurred from the same location. This rockfall, totaling 10,324 cubic meters (27,875 tons), buried trees at the base of the cliff and generated a huge dust cloud that fanned out across the valley. A small rock fragment hit a vehicle traveling on Northside Drive, puncturing the sunroof and injuring the driver. Northside Drive was closed for 24 hours as geologists assessed the potential for additional activity. Several smaller rockfalls occurred from this same area in October and November.


Other substantial rockfalls in 2017 occurred at Little Windy Point on the El Portal Road, Ahwiyah Point, Glacier Point, El Capitan, Middle Cathedral Rock, and Hetch Hetchy. 


It is very likely that there were additional rockfalls and rockslides in 2017, but these events either were not witnessed or went unreported. If you witness a rockfall of any size, encounter fresh rock debris, or hear cracking or popping sounds emanating from the cliffs, please contact park geologist Greg Stock at 209-379-1420 or greg_stock@nps.gov, or contact Park Dispatch by dialing 911 within the park. Documented rockfalls are added to the park database (http://pubs.usgs.gov/ds/746/), enabling long-term evaluation of rockfall activity to improve public safety.  (G. Stock)
