A combination of water management practices has contributed to notable groundwater gains in Central Arizona despite the region dealing with long-term water stress, according to a study led by researchers at The University of Texas at Austin and collaborators in Arizona and Colorado. https://phys.org/news/2025-03-groundwater-gains-arizona-policies-climate.html Earth Sciences Mon, 31 Mar 2025 15:15:04 EDT news662652901 Water from Colorado's West Slope basins plays a vital role in supporting the economy and natural environment across seven western U.S. states, but a new study finds that even under modest climate projections, the basins face a potential tipping point where traditional water delivery levels to Lake Powell and other critical areas may no longer be sustainable. https://phys.org/news/2024-11-colorado-river-basins-drought.html Earth Sciences Wed, 13 Nov 2024 15:34:01 EST news650734438 While documenting fossil tracksites along a stretch of Lake Powell, a Glen Canyon National Recreation Area (Glen Canyon NRA) field crew discovered the first tritylodontid bonebed found in the Navajo Sandstone in Utah. These extremely rare fossils are one of the more important fossil vertebrate discoveries in the United States this year. https://phys.org/news/2023-10-rare-jurassic-fossils-lake-powell.html Paleontology & Fossils Mon, 16 Oct 2023 10:12:35 EDT news616669950 Lakes Powell and Mead, the two major reservoirs fed by the Colorado River, reached record lows this year nearing 25% capacity. An ongoing megadrought, impacts from climate change and systematic overuse have created a deep management crisis. Although there is growing public acknowledgement that cuts in consumptive use are inevitable and that policy changes are needed, renegotiation of the rules governing this critical shared river are fraught with complexity and impeded by competing priorities between states. https://phys.org/news/2022-07-stabilize-colorado-river.html Environment Thu, 21 Jul 2022 14:00:01 EDT news577618901 Usually when a geologist walks up to a sedimentary rock outcrop and starts scanning the layers of sand, mud and silt now turned to rock, they're looking through millions of years of deep time to deduce what happened in that place in the world over many thousands of years to create that particular rock. https://phys.org/news/2022-04-exposed-sediments-reveal-decades-lake.html Earth Sciences Tue, 05 Apr 2022 16:28:05 EDT news568394879 A new study led by the University of Colorado Boulder reveals the complex history behind one of the Grand Canyon's most well-known geologic features: A mysterious and missing gap of time in the canyon's rock record that covers hundreds of millions of years. https://phys.org/news/2021-08-geologists-grand-canyon-mysterious-gap.html Earth Sciences Thu, 19 Aug 2021 16:00:05 EDT news548607597 Researchers from Oregon State University say ecological data gathered during a recent low-flow experiment in the Grand Canyon is a key step toward understanding Colorado River ecosystems as the amount of water in the river continues to decline. https://phys.org/news/2021-06-low-flow-colorado-river-eventual-grand.html Earth Sciences Fri, 25 Jun 2021 10:42:35 EDT news543836552 Even under modest climate warming scenarios, the continental United States faces a significant loss of groundwater—about 119 million cubic meters, or roughly enough to fill Lake Powell four times or one quarter of Lake Erie, a first-of-its-kind study has shown. https://phys.org/news/2020-02-groundwater-depletes-arid-american-west.html Earth Sciences Thu, 13 Feb 2020 15:28:44 EST news500830117 Utah's iconic Rainbow Bridge hums with natural and man-made vibrations, according to a new University of Utah study, published September 21 in Geophysical Research Letters. The study characterizes the different ways the bridge vibrates and what frequencies and energy sources cause the rock structure to resonate. The vibrations are small, according to geology and geophysics professor Jeff Moore, but the study provides a baseline measure of the bridge's structural integrity and shows how human activities can rattle solid rock. https://phys.org/news/2016-09-resonance-rainbow-bridge-natural-vibrate.html Earth Sciences Wed, 21 Sep 2016 13:43:13 EDT news393684183
