The Pika Fire burning in Yosemite National Park consumed more than 500 acres of brush and timber by Sunday morning with no containment, officials in the park reported.

The lightning-sparked blaze erupted June 29 northwest of North Dome in the park and officials do not anticipate it will be fully controlled before July 30.
