Petrified Tree

The Petrified Tree, located near the Lost Lake trailhead, is an excellent example of an ancient redwood, similar to many found on Specimen Ridge, that is easily accessible to park visitors. The interpretive message here also applies to those trees found on Specimen Ridge.

Specimen Ridge

Specimen Ridge, located along the Northeast Entrance Road east of Tower Junction, contains the largest concentration of petrified trees in the world. There are also excellent samples of petrified leaf impressions, conifer needles, and microscopic pollen from numerous species no longer growing in the park. Specimen Ridge provides a superb "window" into the distant past when plant communities and climatic conditions were much different than today.

Tower Fall

Tower Fall is the most recognizable natural feature in the district. The 132-foot drop of Tower Creek, framed by eroded volcanic pinnacles has been documented by park visitors from the earliest trips of Europeans into the Yellowstone region. Its idyllic setting has inspired numerous artists, including Thomas Moran. His painting of Tower Fall played a crucial role in the establishment of Yellowstone National Park in 1872. The nearby Bannock Ford on the Yellowstone River was an important travel route for early Native Americans as well as for early European visitors and miners up to the late 19th century.

Calcite Springs

This grouping of thermal springs along the Yellowstone River signals the downstream end of the Grand Canyon of the Yellowstone. The geothermally altered rhyolite inspired the artist Moran; his paintings of this scene were among those presented to Congress in 1872, leading to the establishment of the park. The steep, columnar basalt cliffs on the opposite side of the river from the overlook are remnants of an ancient lava flow, providing a window into the past volcanic forces that shaped much of the Yellowstone landscape. The gorge and cliffs provide habitat for numerous wildlife species including bighorn sheep, red-tailed hawks, and osprey.

Yellowstone River and its Tributaries

The Yellowstone River and its tributaries provide habitat for numerous bird and fish species.
