Cracks in the earth and settling of the ground in areas of the Cedar Valley, both believed to be caused by over-pumping of the underground aquifer, were the focus of a special Central Iron County Water Conservancy District work meeting March 27.

Watch these interviews featuring one of our geologists, Tyler Knudsen, talk about the ground fissures and their causes.

Giant cracks running through an Iron County subdivision are the result of drawing too much water from the ground, according to a new state report.


Report: Cedar Valley Ground Slowly Sinking

A new report from the Utah Geological Survey shows that the ground in Iron County’s Cedar Valley is slowly sinking due to groundwater pumping.

Water from a recent storm fills shallow pools on the Permian-age White Rim Sandstone near the White Rim Trail. The trail traverses a broad bench formed by the resistant sandstone above the confluence of the Green and Colorado Rivers.

Over-pumping of groundwater from a deep aquifer in Cedar Valley for the past three decades has caused the ground to sink and crack, inflicting damage on a would-be subdivision and putting future development at risk.

Land Subsidence and Earth Fissures in Cedar Valley, Iron County, Utah

A just-released report from the Utah Geological Survey (UGS) shows the ground has been sinking in some areas around Cedar City for decades. The comprehensive 116-page report presents the results of an investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah, primarily due to groundwater pumping. “The sediments in the Cedar Valley that form the groundwater aquifer contain a significant amount of fine-grained silt and clay sediments. Those sediments become compacted when water is removed and the ground begins to sink,” said Tyler Knudsen, UGS project geologist.
