Located in Cimarron County, Oklahoma, Black Mesa State Park is a state park. It sits roughly 35 km (22 mi) WNW of Boise City.
Black Mesa State Park is an Oklahoma state park in Cimarron County, near the western border of the Oklahoma panhandle and New Mexico. The park is located about 15 miles (24 km) away from its namesake, Black Mesa, the highest point in Oklahoma (4,973 feet (1,516 m) above sea level). The mesa was named for the layer of black lava rock that coats it. The associated nature preserve is open to hiking and contains 1,600 acres (6.5 km2) and is home to 23 rare plants and 8 rare animal species. The nearest community is Kenton, Oklahoma. The nearest town is Boise City, Oklahoma. The park is the darkest sky for any state park site in Oklahoma; the site is a Bortle 1 zone, thus making the park a big attraction for astronomers to view the night sky.From the Wikipedia article “Black Mesa State Park”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Black Mesa State Park, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.
