Tower-Roosevelt Area Natural Highlights
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, 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.
Did You Know?
There are more people hurt by bison than by bears each year in Yellowstone. Park regulations state that visitors must stay at least 25 yards away from bison or elk and 100 yards away from bears.
