Having said all that, I'm not sure that I've ever actually seen a fissure. There was a big story about four years ago, after particularly heavy rains, about a driveway that was destroyed when a fissure opened underneath it and another one about an unfortunate horse that fell into a fissure. You are taking a risk when you buy a residential property in some areas, like this one that the tire's message refers to, but I think the media has blown Queen Creek's fissures out of proportion.

I was driving in the area south of Hunt Highway when I came across this sign, which I think refers to the soil and a risk of fissures developing. Queen Creek is known for having fissures, tension cracks in the Earth's surface that have formed as a result of groundwater pumping. Intense rainfall can erode the sides of these cracks, expanding them into substantial chasms. The typical fissure is 3-10 feet wide and 5-20 feet in apparent depth.
