Kiz is a ghost town located in arid Clark Valley, in the sparsely populated eastern part of Carbon County, Utah, United States.

[1] Most of the homesteaders came in the period 1910–1916,[2] including a successful Basque sheepherder named Gratien Etchebarne who filed the first legal claim to the land in 1916.

Trying to save all the available water, residents dug numerous wells,[2] and although there was no stream nearby,[1] they built a large reservoir for irrigation.

[3] In 1921 the American Legion promoted Clark Valley as a home for World War I veterans to establish themselves, making claims of available irrigation water that never actually arrived.

[1] The population reached its peak in 1925,[2] and a post office was established in 1926 in George Mead's general store.
