A gaping, 2-mile-long crack has opened in the barren earth in Arizona, and it will likely continue to grow, geologists say.
Recent footage from a flyover by an Arizona Geological Survey drone revealed the extent of the huge fissure in Pinal County, between Casa Grande and Tucson, showing the enormous gash splitting the barren land. The crack is so big that it dwarfs people walking along its edges in the video.
The northern part of the fissure, which is older and partially filled in, is shallow, while the southern portion is tens of feet deep in some spots, according to Joseph Cook, a geologist with the Arizona Geological Survey (AZGS). [Check Out Insane Photos of Sinkholes]
