Whole-rock chemistry and radiocarbon ages for tephras and lavas used to establish the eruption history over the past 15 kyr at Laguna del Maule volcanic field along the Chilean-Argentine border Whole-rock chemistry and radiocarbon ages for tephras and lavas used to establish the eruption history over the past 15 kyr at Laguna del Maule volcanic field along the Chilean-Argentine border
The Laguna del Maule (LdM) volcanic field as mapped by Hildreth and others (2010) includes 36 postglacial rhyolite and rhyodacite coulees and domes that erupted from 24 separate vents that encircle the 54-km2 lake basin. Although recognizing that such effusive events commonly have accompanying explosive phases, pursuing downwind tephra studies into Argentina was not done then and the...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the northernmost Park Range and southernmost Sierra Madre, Jackson and Routt Counties, Colorado (Snyder, 1980). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as...
Pelican Island and Pass La Mer to Chaland Pass Restoration (BA-38) Coastal Wetlands Planning, Protection and Restoration Act Pelican Island 2021 detailed habitat classification Pelican Island and Pass La Mer to Chaland Pass Restoration (BA-38) Coastal Wetlands Planning, Protection and Restoration Act Pelican Island 2021 detailed habitat classification
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...
