Buried Nickel From Mars Lures Hunters to Texas Desert: Travel

I’m standing where blue sky meets the yellow sand of Texas desert and a chance encounter with the extraterrestrial changed forever the texture of this landscape.

Some 63,000 years ago, a school-bus-size mass of molten iron and nickel from the asteroid belt between Mars and Jupiter plummeted to Earth here, leaving a hole 100 feet deep and 550 feet across. The explosion, three times the force of the atomic bomb dropped on Hiroshima, spewed shrapnel for a mile and a half in every direction, punching four more small craters nearby.
