Benito Hernandez stands outside his home near San Jose de Las Piedras in Mexico's northern state of Coahuila on January 16. For over 30 years, Hernandez, his wife Santa Martha de la Cruz Villarreal and their family have lived in a sun-dried brick home with a huge 130-foot-diameter rock used as a roof. The dwelling is found close to the town of San Jose de Piedras, a remote community located in the arid desert of Coahuila, about 50 miles from the border with Texas.

A woman carries a a baby past a 340-ton megalith rock, which is to be part of artist Michael Heizer's artwork "Levitated Mass", as it is seen on a transport vehicle in the middle of the road, about 5 miles from downtown Los Angeles on Friday. The massive granite boulder is on the last leg of an 11-night, 106-mile journey to the Los Angeles County Museum of Art where it will become the centerpiece of artist Heizer's 'Levitated Mass.' It is expected to arrive in the early morning hours on Saturday and will take weeks to put in place before the installation opens to the public in late spring or early summer. The $10 million cost to move the boulder was paid for by the museum through private donors.
