Giant fracture on Navajo Reservation is part of fault system

The giant 'crack' reported on the Navajo Reservation in northeast Arizona, appears to be part of an extensional fault system (graben) previously mapped in 1984 by George Billingsley of the USGS, according to AZGS geologist Joe Cook.   Joe linked the mapped fault with aerial imagery (below).

    In the background of the photo is El Paso Natural Gas Co.'s Leupp Compressor Station.
    That crack has been there for many years, with a dilapidated fence surrounding it.
