Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025 Ground-Based LIDAR Data of a Section of the Point Bonita Lighthouse Trail, Golden Gate National Recreation Area, Marin County, California, January 23, 2025
A rockfall occurred between the night of January 5 and the morning of January 6, 2025 on the Point Bonita Trail in the National Park Service Golden Gate National Recreation Area, California. The rockfall originated from a granodiorite rock face in the Franciscan Formation and deposited approximately 25 cubic meters of rock on the pedestrian trail below. The U.S. Geological Survey...
Ground-based lidar data of the southeast face of El Capitan, Yosemite National Park, California, May 4, 2022 Ground-based lidar data of the southeast face of El Capitan, Yosemite National Park, California, May 4, 2022
We collected two ground-based (terrestrial) lidar scans of the southeast face of El Capitan cliff, located in Yosemite National Park, California. El Capitan is one of several iconic granitic cliffs in Yosemite and rises approximately 1000 meters above the floor of Yosemite Valley. The scans were collected from the same location and from a single vantage point on the edge of El Capitan...
Estimating the hypothetical endowment of critical minerals and other commodities in porphyry copper mine waste in the Four Corners states, USA Estimating the hypothetical endowment of critical minerals and other commodities in porphyry copper mine waste in the Four Corners states, USA
Society is fundamentally dependent upon commodities that are used in end-use products for the aerospace, defense, energy, telecommunication, and transportation sectors, resulting in centuries of mining to supply these commodities and materials. Waste from these mining operations can remain on the landscape indefinitely, but there is a lack of national understanding of the distribution...
