Santa Fe impact structure
Coordinates: 35 ° 45 ′ 0 ″ N , 105 ° 56 ′ 0 ″ W.
The Santa Fe impact structure is a heavily eroded remnant of an impact crater in the Sangre de Cristo Mountains northeast of Santa Fe, New Mexico . In 2005, a geologist discovered at the cut of the New Mexico State Highway 475 between Santa Fe and Hyde Memorial State Park , cones of rays that can only naturally form when a meteorite hits. The age of the impact structure is estimated to be 1.4 to 1.6 billion years. The underground rock of the former crater now forms a mountainous region. The cones of rays are found over a distance of about one mile (1.6 km) and are interpreted as the central area of a formerly larger crater.
