For more than 700 years, the Ancestral Pueblo people called what is now Mesa Verde National Park home. Their dwellings – elaborate stone communities – blend into the sheltered alcoves of Colorado’s canyon walls. Today, visitors can explore these spectacular cliff dwellings with ranger-guided tours from late spring to early fall. Photo courtesy of Chris Wheeler.

A colossal tribute to four of our greatest presidents, Mount Rushmore National Memorial in South Dakota captivates and overwhelms nearly 3 million visitors a year. Most popular during the summer, we think Presidents’ Day is a perfect time of year to feature this remarkable park. Say hi to Washington, Jefferson, Lincoln and Theodore Roosevelt when you go!

These two little red foxes snoozing at Maine’s Acadia National Park are beyond cute! A mother fox gives birth to a litter of 2-12 kits, which the parents raise together. When the kits are about seven months old, they’re ready to strike out on their own. Check out more photos of cuddly animals: http://on.doi.gov/affectionateanimals.
