Explanation:

[STC0011383]. Carlsbad Caverns National Park in New Mexico’s Guadalupe Mountains features underground restaurants open to the public. The Underground Lunchroom, established in the 1920s, is located in The Big Room, a roughly 4,000-foot-long limestone cavern. Visitors can enjoy a beautiful display of stalagmites and stalactites in the Big Room, but the food is limited to cold sandwiches (heat would harm the environment). It’s the largest cave chamber in North America, and Will Rogers famously referred to it as “the Grand Canyon with a roof over it.”
