Black Mesa is located in Oklahoma's panhandle along the tri-state border with Colorado and New Mexico. The nature preserve consists of approximately 1,600 acres where visitors can hike and enjoy 23 rare plants and eight rare animal species. The unique area marks the point where the Rocky Mountains meet the shortgrass prairie and many species are at the easternmost or westernmost point of their natural range. In addition to being an excellent location for wildlife watching, Black Mesa State Park boasts some of the darkest nighttime skies on publicly accessible land in the country. The dark skies draw countless astronomy enthusiasts to the area every year as they make star gazing ideal.
