An Enormous Crack Just Opened Up In The Middle Of The Arizona Desert

The Arizona Geological Survey is monitoring a 2-mile long crack that has opened up in the Arizona desert. Recent drone flights over the crack reveal that it has continued to grow both in length and width in Pinal County, to the southeast of Phoenix.

Scientists are actively monitoring the crack and took drone video of the extent of the fissure as normal documentation of an area prone to large cracks in the Earth. The northern portion of the crack is older and partially filled in by eroding sediment and from collapse of the crack’s edges. Meanwhile, the southern portion remains 25 to 30 feet deep and 10 feet across. The fissure tapers out toward each edge but the southern edge continues to grow in length and widen.

The crack was first noticed in 2014 during a review of Google Earth images across the landscape to look for abnormal features. This prompted the Arizona Geological Survey to visit the site and measure the length, width, and depth of the massive fissure. They noticed the size was significantly larger than what appeared in the Google Earth imagery and had grown to almost 2 miles long. The crack had grown significantly due to local heavy rains that enhanced erosion and collapse of the overlying sediment to reveal the underground fissure.

The fissure is a surface expression of a larger open void underground, which ultimately is a result of desiccation due to aquifer drawdown from local populations and agriculture. Agriculture in the region relies on drawdown of the underlying porous sandstone aquifers for potable water. This, in turn, causes significant compaction of sediment that was otherwise held up by water in the sediment pore spaces. After decades of aquifer depletion, the underlying sedimentary rocks eventually fail and cause fissures or cracks to appear both in the subsurface and surface of the Earth.

This region of the United States is prone to cracks developed from extensive groundwater usage. Specifically, cracks form along the margins of subsidence areas and along nearby mountain fronts, where more competent rock is not prone to collapse. The Arizona Geological Survey actively measures 26 study areas of fissures and have mapped a combined 170 miles of fissures in the region.

Geologists with the Arizona Geological Survey expect the crack to continue to grow at the southern extent. They expect the underground extent of the fissure is significantly larger than the surface expression seen by the drone footage. Thankfully the crack is in the middle of the desert and likely not a harm to humans as long as no one attempts to walk or drive up to the crack. However, the crack could cause harm to local cattle that may use the area for grazing.

Todd your ass made UFO news literally! Aimee Mecca

Guest

Wtf are you doing reading UFO news? Crack? More like fooking crack pots. Smh.

Guest

Todd WTF did u do???

Guest

😂

Guest

Looks like an old creek bed

Guest

Underground excavating

Guest

Termites?

Guest

Hopefully trump will fall in it

Guest

FRACKING

Guest

See you at Arizona bay

Guest

Cthulhu Is Coming!

Guest

It’s probably a fault line that would be logical.

Guest

Part of Cali’s plan to secede?

Guest

The Earth moans.

Guest

The black ops (secret) military and construction folk who build the under ground bases (D.U.M.B.S) need to spend more time on the surface of the areas that they drill under…
or else this happens…

Guest

uh-oh… 😮

Guest

Wait Wait Wait….. A crack opens in a desert and aliens are around? A crack opened my back side…. if aliens were anywhere around that crack something’s going to die

Guest

Excellent let’s hope it goes all the way to the White house!

Guest

Rikki Lee Robson Well get the lead out…….:D

Guest

hey now it has to wait until after I leave 😝

Guest

Better yet let’s hope it sends CA into the ocean.

Guest

A new bridge.
