You can add Chaco Culture National Historical Park to the list of National Park System sites portrayed on a quarter.

These ten cultural-historical parks deserve a darn sight more attention than they've been getting.

Still standing centuries after they were built, the ruins at Chaco Culture National Historical Park in northern New Mexico have weathered centuries of storms, winds, and tortuous sun. More recent structures have struggled to stand such a test of time.

When you're planning a visit to a national park, don't overlook the dark side. No, we aren't suggesting you join forces with Darth Vader, but many parks offer a great opportunity to enjoy a view that's unfortunately becoming increasingly rare—the night sky. An upcoming nationwide event and several other opportunities can help you protect and enjoy the beauty of the night.
