“I cannot endure to waste anything so precious as autumnal sunshine by staying in the house." - Nathaniel Hawthorne Anyone else feeling this way this weekend? Here's to sunny skies no matter where you are!

We recently honored volunteers and volunteer groups who exemplified outstanding service in Yosemite National Park at our annual volunteer awards ceremony. Congratulations to the nine 2017 recipients who worked to restore habitats and landscapes, assisted with preventive search and rescue, provided information to visitors and much more! Volunteers are an integral part of helping keep national parks running. Each year, around 12,400 volunteers donate over 167,000 hours of work in Yosemite.

Some autumn color is coming to Yosemite Valley and peaking in many higher elevations in the park as dogwoods, oaks, and other deciduous trees prepare to lose their leaves for the winter. #Yosemite #NationalPark #FallColor

Residual smoke from the Empire Fire is still visible along the Glacier Point Road, adding silver to the purple evening light on the Clark Range. Visibility and air quality is still good in most areas of the park, including Yosemite Valley. #YosemiteNationalPark #nature #nofilter

The high snow pack from last winter continues to affect Yosemite Valley, even in early fall. Mirror Lake, which usually dries up by August, still has water, providing a tranquil foreground for Half Dome and Ahwiyah Point.

The bright red berries of the mountain dogwood (Cornus nuttallii) are ripening in Yosemite Valley. While not very palatable to humans, dogwood berries are commonly eaten by birds and other animals. #YosemiteNationalPark #fall #autumn

"Before many years... these hundreds will become thousands and in a century the whole number of visitors will be counted by millions. An injury to the scenery so slight that it may be unheeded by any visitor now, will be one multiplied by these millions." - Frederick Law Olmsted, 1865. If you ever visit Olmsted Point, you may wonder how it got its name. It was named for Frederick Law Olmsted, Sr. and his son, Frederick Olmsted, Jr. Olmsted Sr. was one of the fathers of American landscape design and the first chairman of the Board of Commissioners of the Yosemite Grant. At the time, Yosemite saw few visitors, but Olmsted (correctly) predicted that many people would want to see Yosemite's wonders in the future. Share one way you help protect Yosemite National Park for present and future generations! #Yosemite #NationalPark

On this day in 1890, Yosemite became the third national park in the United States, preserving thousands of square miles of wilderness. In the original legislation, the act dictated that the park "shall provide for the preservation from injury all timber, mineral deposits, natural curiosities, or wonders within said reservation, and their retention in their natural condition." Today, the park attracts millions of people around the world drawn to these "natural curiosities and wonders," such as towering granite cliffs, waterfalls, lush meadows, and vast forests. Which of Yosemite's famous wonders is your favorite? #Yosemite #YosemiteNationalPark #HappyBirthday #Wonder

Happy National Public Lands Day! What better way to celebrate our nation's public lands than to roll up our sleeves and help restore them? Across the US today, hundreds of thousands of people volunteered in trail maintenance projects, community clean ups, invasive species removal, and so much more! A big thank you to those who participated in Yosemite Facelift today and this week, and to volunteers who help take care of the park year-round! #Facelift #NPLD

The rockfall on Thursday, September 28 was substantially larger than Wednesday's series of rockfalls that occured in the same area on El Capitan. The park geologist has measured the rockfall to have been 10,250 cubic meters in volume, or about 30,500 tons of granite. The dimensions for the source area are about 395 feet tall, 148 feet wide, and up to 26 feet thick. The September 28 rockfall ranks as the 29th largest rockfall in Yosemite Valley on record. A number of geologic processes set the stage for rockfalls including glaciation, weathering, and bedrock fractures. Triggering mechanisms like water, ice, earthquakes, fluctuation in temperature, and vegetation growth are among the final forces that cause unstable rocks to fall.

Yesterday, starting at approximately 1:52 p.m. Pacific time, seven successive rockfalls occurred on the southeast face of El Capitan, dropping 1300 tons of rock. This type of rockfall is typical in volume and behavior. The area of El Capitan, near Horsetail Fall, has experienced many rockfalls since 2010, most recently in April 2014. While the rockfall may have been typical, the results were not. Two climbers were at the base of El Capitan when the rockfall occurred, resulting in one fatality and one serious injury. All other people in the area have been accounted for and search efforts have been concluded.
