YELLOWSTONE - 150 YEARS

Yellowstone National Park preserves one of the largest, temperate-zone ecosystems on Earth. About 99% of the Park is managed as wilderness and Park biologists continually work to promote its natural ecological processes by restoring populations of many native species - in constructing nesting platforms for swans, suppressing non-native fish, establishing wolf den and bear management areas, rehabbing injured raptors and reviving extirpated, endangered or threatened wildlife.

Yellowstone's fortune is its wildness.

The Druid Peak Pack of Lamar Valley

That single hunter's bullet shattered the entire Lamar Canyon pack. While the alpha male and one of his daughters have returned to the Lamar Valley, the rest of the pack has stayed outside the park and now lives in territory where they risk being hunted. Apr 2, 2014
