About Yellowstone National Park 
Established in 1872, Yellowstone was the world’s first national park, and is still one of the largest remaining vestiges of American wilderness in the lower 48 states. An incredibly diverse place, Yellowstone is home to:

• Grizzly bear, wolves, bison, elk, moose, bighorn sheep, mule deer, bald eagles, and trumpeter swans.
• The greatest concentration of geothermal features on Earth, as well as thermal pools, mud pots, and other wonders.
• A renowned trout fishery, and one of the most extensive petrified forests in the world.

Yellowstone at Risk
When Lewis and Clark explored the West, as many as 100,000 grizzly bears roamed the land from the Mississippi River to the Pacific Coast, but today fewer than 1,500 remain. In addition, over the years, the Park’s ecosystem has faced an increasing number of threats including: energy development, mining, logging, global warming, suburban sprawl, air pollution and decreasing wildlife populations.

Sierra Club and Yellowstone
The Sierra Club has worked to protect the Yellowstone region for nearly 100 years; opposing damaging plans for logging, oil and gas development, and geothermal energy development adjacent to the park; defending Yellowstone’s wolves and grizzly bears in the courts; and advocating for the removal of all private snowmobiles from the park in favor of “snowcoaches” which have significantly less impact on air quality, habitat disturbance and water pollution.

By your sponsorship, you can support the Sierra Club’s conservation efforts to protect Yellowstone and ensure that its magnificent scenery and wildlife can be preserved for generations to come.
