Clayton Lake State Park is a state park of New Mexico, United States, featuring a 170-acre (69 ha) recreational reservoir and a fossil trackway of dinosaur footprints. It is located 15 miles (24 km) north of Clayton, close to New Mexico's border with Colorado, Oklahoma, and Texas. The park is accessed via New Mexico State Road 455. The landscape is characterized by rolling grasslands, volcanic rocks, and sandstone bluffs, set on the western edge of the Great Plains.

Visitor activities include picnicking, camping, and fishing at the lake, as well as viewing one of the most extensive dinosaur trackways in North America. Clayton Lake was created by the New Mexico Department of Game and Fish in 1955 as a fishing lake and winter waterfowl resting area.From the Wikipedia article “Clayton Lake State Park”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Clayton Lake 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 25° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.
