Today's image gives us a glimpse of beautiful Grand Teton National Park, in the United States' least populous state, Wyoming. The park, established in 1929, includes numerous lakes, the Snake River and the Teton Range, famed for its series of sharp, jagged peaks. Bring your binoculars with you, and if it's summertime, be on the lookout for pronghorn, who travel about 150 miles to get there. They aren't the only creatures to visit seasonally; elk and bison are also summer visitors. These migrations play a vital role in the ecosystem of Grand Teton National Park. The animals help disperse seeds and provide food for predators.
