Signed into law by President Ulysses S. Grant, America's first national park was set aside to preserve and protect the scenery, cultural heritage, wildlife, geologic and ecological systems and processes in their natural condition for the benefit and enjoyment of present and future generations.

Yellowstone serves as the core of the Greater Yellowstone Ecosystem, one of the last and largest nearly intact natural ecosystems on the planet. Yellowstone has the most active, diverse, and intact collections of combined geothermal features with over 10,000 hydrothermal sites and half the world's active geysers. The park is also rich in cultural and historical resources with 25 sites, landmarks, and districts on the National Register of Historic Places.

Based on the park’s location at the convergence of the Great Plains, Great Basin, and Columbia Plateau, 27 Native American Tribes have historic and modern connections to the land and its resources. For over 10,000 years before Yellowstone became a national park, it was a place where Native Americans lived, hunted, fished, gathered plants, quarried obsidian, and used thermal waters for religious and medicinal purposes.

Park managers have learned many lessons during Yellowstone's 150 years. In the early 1900s, the government killed nearly all predators in the park, and the bison population was hunted to less than two dozen. Later that century, the fires of 1988 burned more than one-third of the park, and the introduction of nonnative lake trout decimated native Yellowstone cutthroat populations. Through modern resource management efforts involving bison, grizzly bears, native fish, gray wolves, wildland fire, and others, Yellowstone's ecosystem is the healthiest it has been in over a century.

Today, Yellowstone is facing new challenges. Employee housing, workforce development, historic preservation, effects of climate change, transboundary wildlife management, increasing visitation, and deteriorating infrastructure are issues impacting Yellowstone's workforce, resources, visitors, and gateway communities. To tackle these challenges, Yellowstone has set five major strategic priorities, each supporting the overarching National Park Service mission and each critical to Yellowstone's success. The priorities are: 1) Focus on the Core (workforce); 2) Strengthen the Yellowstone Ecosystem and Heritage Resources; 3) Deliver a World-Class Visitor Experience; 4) Invest in Infrastructure; and 5) Build Coalitions and Partnerships. Within each of these strategic priority areas are a wide range of actions designed to achieve success. Learn more about Yellowstone's recent successes and challenges, along with priorities and actions park managers intend to pursue in the future, in our State of the Park report.

Yellowstone is bigger than its boundary. Each of our partners play a vital role in making decisions that protect Yellowstone for future generations and improve the positive conservation, environmental, economic, and social impacts the park provides this region and the country. As stewards of this inspiring place, it is an opportunity for us to reflect on the lessons of the past and strengthen Yellowstone for the future by making decisions that protect the health of the park for centuries to come.

During March-August 2022, the park and partners provided opportunities to reflect on 150 years of protecting the park, highlighted successes in the ecosystem, and opened dialogue on the lessons learned from yesterday, the challenges of today, and a vision for tomorrow. We focused on the stewards of Yellowstone, conservation and historic preservation, visitor experience, infrastructure, Tribal Nations, and partner engagement via social media, a bimonthly virtual video series featuring various subject matter experts, and a range of both virtual and in-person activities. Of particular importance to Yellowstone during the commemoration was to be reflective, intentional, inclusive, and impactful.

Focus on the Core: Employee Health & Wellness


To promote employee wellness and commemorate 150 Years of Yellowstone, employees skied, snowshoed, walked, and ran a combined 1,955 miles in the park during February and March! This activity highlighted mental wellness and provided tools to employees to help build resiliency during some of the darkest days of the year. Following the event, the park hosted a certified counselor who met with employees to discuss work-life balance, how to cope with loss, and one-on-one private counseling sessions. Additionally, the park is participating in an employee health and wellness survey this year to gather information about what supports, or hinders, the health and well-being of park employees. The goal of this project is to address the most pressing health issues employees face and provide better support for our community now and into the future.

New Employee Housing Ribbon-Cutting

Spring 2022 | Mammoth Hot Springs

Yellowstone initiated a $40 million housing improvement effort to substantially upgrade National Park Service employee housing across the park by replacing 64 outdated trailers. The old trailers, located throughout the park, were 40-60 years old and in substandard condition. This project also upgraded utilities and incorporated landscape designs to develop a sense of community. The park saved an estimated $36 million from the original housing improvement plan proposal.

Tower-Roosevelt to Chittenden Road Ribbon-Cutting

Spring 2022 | Tower Junction

After two years of construction and roughly $28 million invested, Tower-Roosevelt to Chittenden Road (near Dunraven Pass) reopened May 27! This segment of road remained largely unchanged since the last improvements in the 1930s. Improvements include widening roughly 6 miles of Grand Loop Road and providing additional/improved pullouts; creating a larger, safer parking area at Tower Fall General Store; improving the trail and overlook for Tower Fall; and reconditioning Chittenden Road and reconstructing the Mt. Washburn parking area. To fund this infrastructure improvement, the park received a grant through the Nationally Significant Federal Lands Program and matched it with fee dollars collected in the park.

Mount Doane Now Named First Peoples Mountain

Spring 2022 | Learn more

Yellowstone National Park announced June 9, 2022, that Mount Doane is now named First Peoples Mountain. First Peoples Mountain was previously named after Gustavus Doane, a key member of the Washburn-Langford-Doane expedition in 1870 prior to Yellowstone becoming the first U.S. national park. Research has shown that Doane led an attack on a band of Piegan Blackfeet in 1870. During what is now known as the Marias Massacre, at least 173 American Indians were killed, of which Doane wrote fondly and bragged about for the rest of his life. First Peoples Mountain is a 10,551-foot peak in the Absaroka Mountains located east of Yellowstone Lake.

Lewis River Bridge Project Groundbreaking

Summer 2022 | South Entrance Road

This $28 million project includes the removal and replacement of the structurally deficient Lewis River Bridge. Beginning spring 2022, the existing 273-foot-long bridge, built in 1960, will be removed, and a new bridge will be constructed immediately downstream to preserve safe visitor access between South Entrance and West Thumb. Parking areas, overlooks, and walkways in this area will be updated and reconfigured to reduce traffic hazards and improve accessibility for visitors. This project is funded through the Great American Outdoors Act and Legacy Restoration Fund. View more photos of this project on our Flickr.

Bison Conservation Transfer Program Expansion Completion

Fall 2022 | Stephens Creek

Since 2019, 182 bison were transferred to the Fort Peck Tribes in northeastern Montana. Of those 182 bison, roughly 140 were transferred to about 20 other member Tribes across North America to start conservation herds. Yellowstone has partnered with Yellowstone Forever and Greater Yellowstone Coalition to more than double the capacity for the Bison Conservation Transfer Program. Together, we’re building a better future for our national mammal. View more photos of this project on our Flickr.
