A proposal to construct a practically 500-mile-long stretch of transmission line in Nevada has been additional delayed due to the invention of potential fossil deposits in its path.
According to E&E News, an environmental overview of the transmission line plan, initially slated to be launched in January, will not be made public for a public remark interval till Could. That’s as a result of the trail of the Greenlink West energy line, because it’s been proposed by NV Vitality, runs via 1.5 miles of Tule Springs Fossil Beds National Monument, established as a Nationwide Park Service website in 2014.
The monument accommodates hundreds of fossils from the Pleistocene Epoch, generally referred to as the Ice Age. For about 90,000 years—until around 12,500 years ago—the area was stuffed with wetlands that preserved the Pleistocene fauna, from mammoths and saber-toothed cats to acquainted creatures like coyotes, jackrabbits, and snails.
The 22,650-acre park sits north of Las Vegas; the transmission line’s 470-mile-long proposed path slices via the monument and from there roughly runs parallel to Nevada’s western border north to the outskirts of Reno.
Based on the Bureau of Land Administration’s website, “the Greenlink West Undertaking could be a system of latest 525-kilovolt (kV), 345-kV, 230-kV, and 120-kV electrical transmission services on personal, state, and federal lands between northern and southern Nevada.”

As it’s at present outlined, the ability line would take a 1.5-mile-long path via the nationwide park, 5 toes inside its borders close to a highway that cuts the park into two segments.
The NPS cautioned in feedback filed to BLM final yr that “The development of the transmission line…could have the potential to influence paleontological assets, together with an undetermined variety of fossil stays and unrecorded fossil websites,” according to the Public Employees for Environmental Responsibility.
The Nationwide Park Service proposed utilizing ground-penetrating radar to detect fossil deposits within the space. These scans, funded by NV Vitality, had been accomplished by Geotech World Consulting, and the outcomes had been published in September. The report described the detection of Pleistocene vertebrate fossils throughout the nationwide monument.
One scan “exhibited a group of anomalies that might nicely be vertebrate fossils,” in keeping with the report, written by Thomas City, a analysis scientist at Geotech World Consulting. (City and colleagues beforehand used ground-penetrating radar to find human and proboscidean trace fossil beds in White Sands National Monument in New Mexico.)
One other scan performed on deposits “that exhibited a considerable amount of small bone fragments eroding out of the floor” detected “various anomalies … a few of which resemble vertebrate fossils.” A 3rd scan revealed proboscidean tusks poking out of an escarpment.
All advised, the deepest scan discovered potential fossils deeper than 33 toes (10 meters). Due to the uncertainty of what was the reason for the anomalies, ground-truth observations (and excavations) could also be needed to grasp precisely what the ability line might disturb, ought to it go forward as deliberate.
As famous by E&E Information, the Bureau of Land Administration has a smattering of federal and guarded lands to navigate, together with an Air Pressure base, Native American tribal websites, and the Desert National Wildlife Refuge, the biggest wildlife refuge outdoors of Alaska.
How BLM and NV Vitality plan to navigate the authorized quagmire stays to be seen; the general public remark interval following the environmental overview’s eventual launch could deliver its personal suite of complaints.
