Heizer's "City" now part of national monument, thanks to POTUS

Using his authority under the Antiquities Act, the president created a protected area spanning roughly 704,000 acres in central Nevada’s Basin and Range, as well as smaller ones in California’s Berryessa Snow Mountain and Texas’ Waco Mammoth. [...]

Broadly supported by environmentalists, [Basin and Range] is also home to a major earthen sculpture, “City” which the artist Michael Heizer has worked to create over nearly half a century. — washingtonpost.com
