Cargill sink formed as a result of solution mining of salt near Hutchinson, Kansas. The sudden collapse of bedrock and near-surface, water-saturated sands into the underground brine-filled cavity created the sinkhole and left the Missouri-Pacific railroad tracks suspended 6 meters in the air. The volume of the crater was estimated at 70,000 cubic meters.

Kansas Supreme Court Strikes
Down Jury Award
TOPEKA, Kansas (AP) - The Kansas Supreme Court strikes down a jury verdict awarding $7.7 million for the 2001 natural gas explosions in which two Hutchinson residents died.
The award had been against Tulsa, Oklahoma-based ONEOK and two of its subsidiaries - Kansas Gas Service and Mid-Continent Market Center. ONEOK owned and operated a natural gas storage facility northwest of Hutchinson.
Experts testified a series of explosions were caused by the escape of 143 million cubic feet of gas from the facility.
In reversing the award in the class-action lawsuit, the court said property owners did not show there was physical damage to their individual properties. Instead, they contended the stigma of danger lowered property values throughout the area.
This is too weird. This whole town is on pins and needles. It started yesterday morning with a huge explosion downtown. The fire still has not gone out. I went there last night and talked to a police officer and he told me that they shut off all possible gas lines and it still won't go out. They do not know what is feeding it. This morning there was another explosion about six blocks from where I live. There is at least 8 natural gas leaks all around the city. I grabbed some things and am waiting this out at my shop right now. They have evacuated by my house. I sent my family to the north side of the city. This is too weird. Has anyone else ever heard of anything like this? Hutchinson is built on salt mines. Makes you wonder if natural gas has built up in them. The National Guard is getting ready to be called out. They are not sure if they need to evacuate the whole town. There is somewhere around 30,000+ people here.
I will keep you all posted as I can.

In January 2001, natural gas exploded in the central Kansas town of Hutchinson, killing two people, destroying two downtown businesses, and creating a series of geyser-like spouts of water and gas. For weeks, Hutchinson residents wondered what had happened and worried about what was coming next.
Today, some of the most heavily examined geology in Kansas lies beneath western Hutchinson, along the probable path that the gas took into town. The Kansas Geological Survey used a variety of techniques to study the area. While the gasís movement isnít completely understood, Survey geologists know a great deal.
Hereís the Surveyís working hypothesis. The source of the natural gas, or methane, appears to be a storage facility west of Hutchinson (near a railroad-siding town named Yaggy). In the 1980ís, salt caverns were created for storing propane in a layer of rock called the Hutchinson Salt Member of the Wellington Formation, about 500 to 600 feet below ground. These same salt beds are mined in Hutchinson and throughout central Kansas.
Salt caverns are effective for gas storage because gas can be quickly introduced, and later removed. Thatís especially useful during times of peak demand, like cold winters.
At Yaggy, the salt didnít fail. But a pipe (one used to put gas in and take gas out) did fail. For at least three days, highly pressurized methane escaped through a hole in the pipe and moved up until it reached a permeable zone near the contact between the Wellington Formation and the overlying Ninnescah Shale. These rocks dip (or are angled) very slightly to the west, and the pressurized gas moved up that dip until it found a way to the surface.
In Hutchinson, a town with a
centuryís history of salt mining, that didnít take long. Gas first exploded
after it moved up an old well that was used to produce mineralized water
for a spa. The second explosion occurred at the site of an abandoned well
that was used to dissolve and mine salt.

|Sinkhole Testing In Reno
June 11, 2008 01:44 PM
Sinkholes in one Kansas County are getting larger. A research group in the county says it can't control the sinkholes. It can only help people prepare.
Brandy Lake is something of a misleading name. The lake east of Hutchinson along US-50 Highway is actually a sinkhole that developed thousands of years ago. The sinkhole is actively, if only gradually, growing.
Salt about 400 feet below the county dissolves when groundwater gets to it causing the ground to sink. Researchers use special vehicles to send sound waves underground. Microphones then pick up echoes and tell them what's happening with the salt.
"We have no control over the natural process," says Rick Miller with the Kansas Geological Survey. "All we can do is respond to it. What we hope to do is acquire this data, interpret this data, and get an edge on Mother Nature, if you will."
Knowing what's in the future can be critical in predicting problems for highways and buildings.
"(We want to) be able to tell our engineers and other folks we may have a problem in this location and get it fixed ahead of time," says Bob Henthorne with KDOT. "We don't want to come out here and have a hole already developed and have it be a surprise."
Testing will continue in Reno County through then end of the month meaning parts of US-50 will be down to one lane. Researchers hope to present their findings in four to six months.

HUTCHINSON, Kan.ĖSix hundred and fifty feet beneath the Kansas prairie, in a mined-out section of a working salt mine, a man in a gray plaid suit sits at a telex machine typing out and receiving messages. This is only a test-the man comes to the salt mine two times a year for a communications drill. But if a nuclear attack had been launched against the United States, the messages he is sending and receiving would be devoted to re-establishing the services of the Federal Reserve Bank in the devastated country.
