Sinkholes

Sinkholes are common where the rock below the land surface is Limestone, Carbonate rock, salt beds, or rocks that can be dissolved by ground water circulating through them. As the rock dissolves, spaces and caverns develope underground. Sinkholes are dramatic because the land usually stays intact for a while until the underground spaces just get too big. If there is not enough support for the land above the spaces then a sudden collapse of the land surface can occur.

The coordinates are for the larger of the 2 sink holes that I have found in the area. The other sink hole can be located at N 40* 32.952  W 110* 25.021

In order to log this cache you must send me the answers to some questions.

1. What water source do you think caused the sinkholes to form?

2. What type of rock do you think dissolved to form these sinkholes?

3. What is the approximate diameter and depth of the sink hole at the posted coordinates. You can use your GPS to get these measurements.

4. A photo is not required to log this cache but would be appreciated.
