Yosemite National Park is best known for its waterfalls, but also deep valleys, grand meadows, ancient giant sequoias, a vast wilderness area, & more.

What a bright day to look ahead to so many bright futures! This week is Constitution Week, celebrating the signing of the United States Constitution. As part of the celebration, Yosemite National Park partnered with U.S. Citizenship and Immigration Services to host a naturalization ceremony at Glacier Point and welcome 43 people from all over the world as newly naturalized United States citizens! Each of these individuals now share the ownership of our public lands, including Yosemite. #ConstitutionWeek #Yosemite #NationalPark #PublicLands #Naturalization #UnitedStatesCitizens
You're hiking in along a trail in Yosemite's high country when, out of the corner of your eye, you see a flash of brown fur! What was that?! More often than not, this is all we see of the American marten in the park. These quick and agile creatures bound from rock to rock and climb trees with with great precision and grace. Martens are omnivorous, hunting for birds and rodents and supplementing their diet with berries and seeds in late summer. Have you seen one in the park? #Yosemite #NationalPark
Fall is a time for changing weather and crazy clouds (which we've had a lot of the last few days). If you're visiting soon, be prepared for a variety of conditions! #Yosemite #NationalPark #Clouds
Fall colors are beginning to show up here in Yosemite, a reminder that cooler temperatures and shorter days are on their way. At this time of year, the black bears in Yosemite are doing their best to gain fat for winter, consuming up to 20,000 calories a day (equivalent to a human eating almost 40 Big Macs in a day)! In autumn, acorns and pine nuts become an important part of a bear’s diet because they are nutritious, high in calories, highly digestible, and seasonally abundant. Black bears regularly raid the caches of squirrels and woodpeckers to get to the conifer seeds and nuts they have stored for the winter, but bears are also excellent climbers and can climb trees, break cone-bearing branches, dismantle the ripe, unopened cones, and consume the seeds. The bear in this photo is at the top of a sugar pine tree, getting ready to climb back down to collect her harvest. #Yosemite #NationalPark
“Yosemite Valley, to me, is always a sunrise, a glitter of green and golden wonder in a vast edifice of stone and space.” –Ansel Adams #Yosemite #NationalPark
Today's #GeologyJargon is "megacrysts." 🤓 Have you ever noticed these strange-looking chunks of crystal sticking out of Yosemite's granite bedrock? These features are called "phenocrysts" or "megacrysts," as in mega-sized crystals! Megacrysts are found most commonly in the Cathedral Peak granodiorite located in the north-eastern part of the park. This rock formed from magma that cooled slowly over millions of years, but large crystals like these indicate that temperature was stable for periods of time. During those times, no active cooling was occurring, allowing the crystals to grow to large sizes. These rectangular masses are made up of the mineral orthoclase feldspar and protrude from rock surfaces because they are more resistant to weathering than the surrounding finer-grained rock. Climbers use megacrysts, which they call "knobs," as foot and hand holds while scaling the granite walls throughout the park. #GeologyJargon #ClimbingJargon #YosemiteRocks #Megacrysts #DontTakeItForGranite
Earlier this summer, the Ferguson Fire caused park closures and even a temporary evacuation of Yosemite Valley. What was it like to be a park ranger in Yosemite Valley without any visitors? One ranger wrote a thoughtful reflection on this temporary separation from their place of work. 📝 "Like many relationships, Yosemite and I began ours as acquaintances. Growing up, I visited Yosemite most winters, exploring the snow blanketed meadows and thin waterfall streams. While working in other national parks and public lands, I dreamed about working in Yosemite Valley. In May, I committed to a 'summer romance"-a seasonal gig as a park ranger. I moved away from friends and family, devoted to this budding relationship. By mid-summer, I was in the honeymoon phase–excited by every new element of the park. That honeymoon phase quickly ended once the flames took off."

The National Park Service recently celebrated its 102nd birthday. It’s hard to think about birthdays without balloons, but released or escaped balloons can travel on the wind and become trash wherever they end up. When they drift into wildlife habitat, deflated balloons can be very hazardous to animals that mistake them for food or get tangled in their strings. They can also be dangerous when they land on power lines and they become an eyesore in the wilderness. 🎈 All three of the balloons pictured were found on a single wilderness patrol in Yosemite National Park. Help us #ProtectYosemite by always deflating balloons after using them and ensuring they are disposed of properly. #Yosemite #NationalPark #ProtectYosemite
Are you planning to hike Half Dome in October? 🏞 For 2018 only, due to a change at recreation.gov, the daily lottery will not operate for hiking dates in October. Instead, anyone wishing to apply for a Half Dome permit for October 1–9 must apply from September 15 through September 24 in a lottery that will function like the preseason lottery, allowing applicants to apply for a range of hiking days. Applicants will be notified of the lottery results on or about Wednesday, September 26. The last day to use the regular daily lottery is September 28 (for a hiking date of September 30). The Half Dome cables will be taken down after October 9. #Yosemite #NationalPark #HalfDome
On September 3, 1964, President Lyndon B. Johnson signed the Wilderness Act, which established the National Wilderness Preservation System. Today, 54 years later, we continue to celebrate this step in conservation. 🖋 Nearly 95 percent of Yosemite is designated Wilderness, which is defined as "an area where the earth and its community of life are untrammeled by man...an area of undeveloped Federal land retaining its primeval character and influence, without permanent improvements or human habitation...has outstanding opportunities for solitude," and "shall be devoted to the public purposes of recreation, scenic, scientific, educational, conservation and historic use." 🌲 The word "Wilderness" can evoke all kinds of emotions–fear, awe, empowerment, solitude, renewal, gratitude. We asked some Yosemite rangers to think about what wilderness means to them. 🏔 What does wilderness mean to you? Let us know in the comments or write it down and take a picture! Use the hashtag #WildYosemite to join in the conversation. #Yosemite #NationalPark #WildernessAct #Wilderness #PreserveAndProtect #WhatWildernessMeansToMe #WildYosemite
We'd like to acknowledge the incredible work of our Yosemite Dispatch team! These hardworking employees solve complex problems at all hours of the night and day and work to ensure the safety of all park employees and visitors. The Yosemite National Park Emergency Communications Center (ECC) is staffed 24 hours a day, seven days a week, 365 days a year. The office is currently staffed with eight permanent dispatchers who handle incidents related to wildland and structure fire, emergency medical response, law enforcement, search and rescue, and a variety of other calls as needs arise. The assistance they provide is not only for Yosemite National Park visitors and employees, but Lassen Volcanic National Park and Devils Postpile National Monument as well. With over five million visitors annually visiting these parks, the ECC is busiest from May through October. The dispatchers handled just under 23,000 incidents in 2017. A total of 3,540 9-1-1 calls were received last year, with July being the busiest month for emergency calls. Thank you dispatchers! #Yosemite #NationalPark #Dispatch #EmergencyCommunications
There are many types of paintbrush (Castilleja genus) found in Yosemite National Park. These flowers put on quite a display in the summer—a burst of reds, oranges, and pinks. This beautiful and commonly seen wildflower has an interesting secret: it’s actually a parasitic plant! It belongs to a group of plants called hemiparasites, meaning that even though they have the ability to photosynthesize and could survive without a host, they also have the ability to take nutrients from other plants if living in close proximity. Paintbrush can parasitize neighboring plants using haustoria, specialized roots that drill into the roots of other plants in order to take their nutrients. #Yosemite #NationalPark #Wildflowers #ParasiticPlants
