Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix Aquifer framework datasets used to represent the Kingshill aquifer, Island of St. Croix
The Kingshill aquifer resides under St. Croix, an Island in the U.S. Virgin Islands. The Island of St. Croix is mountainous in the northwestern and eastern regions of the island and the central and southwest regions contain rolling hills and plains. The Kingshill aquifer underlies the plains of St. Croix. The aquifer is composed primarily of limestone and marl and has a maximum saturated
Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma, New Mexico Aquifer framework datasets used to represent the Rush Springs aquifer, Oklahoma, New Mexico
The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer...
Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada Aquifer framework datasets used to represent the Southern Nevada volcanic-rock aquifers, Nevada
The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption...

The Western Interior Plains aquifer system is located in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming and covers an area of more than 220,800 square miles. The thickness of the aquifer system ranges from 500 feet in eastern Colorado (HA 730-D) to as much as 10,000 feet in western Oklahoma (PP_1414B). This aquifer system...
Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma Aquifer framework datasets used to represent the Central Oklahoma aquifer, Oklahoma
The Central Oklahoma aquifer underlies an area of about 2,900 square miles in central Oklahoma. The aquifer is in the Central Lowland Physiographic Province and consists of Garber Sandstone and the Wellington Formation, which are part of the Sumner Group of Permian age. The maximum thickness of the aquifer is about 1,000 feet with a saturated thickness ranging from 150 to 650 feet. The...
Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico Aquifer framework datasets used to represent the Roswell Basin aquifer system, New Mexico
The Roswell Basin aquifer system is located in southeastern New Mexico. It is composed of an alluvial aquifer and an underlying carbonate-rock aquifer. The aquifer covers an area of about 2,200 square miles and the alluvial aquifer covers about 1,200 square miles of the eastern half of this area. The alluvial aquifer primarily consists of Quaternary sediments and the carbonate-rock...
Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington Aquifer framework datasets for the Willamette Lowland basin-fill aquifer, Oregon and Washington
The Willamette Lowland basin-fill aquifers (hereinafter referred to as the Willamette aquifer) is located in Oregon and in southern Washington. The aquifer is composed of unconsolidated deposits of sand and gravel, which are interlayered with clay units. The aquifer thickness varies from less than 100 feet to 800 feet. The aquifer is underlain by basaltic-rock. Cities such as Portland...
Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma Aquifer framework datasets used to represent the Ada-Vamoosa aquifer, Oklahoma
The Ada-Vamoosa aquifer resides in the Central Lowland Physiographic Province in east-central Oklahoma and ends at the Kansas State line. The aquifer underlies an area of about 2,300 square miles. The aquifer consists mainly of layers of fine to coarse-grained sandstone irregularly interbedded with shale and limestone. The rocks are in the Ada and the Vamoosa Groups are Pennsylvanian age...
Aquifer framework datasets used to represent the Marshall aquifer, Michigan Aquifer framework datasets used to represent the Marshall aquifer, Michigan
The Marshall aquifer underlies much of the Lower Peninsula of Michigan and has a maximum thickness of 493 feet (Lampe, 2009). The aquifer consists mainly of medium-grained sandstone and is overlain by Pennsylvanian-age rocks and glacial deposits and underlain by the Devonian-Mississippian-age confining unit. The Marshall aquifer is one of the most productive aquifers in the state where
Postfire Seedlings and Resprout Recruitment by Ceanothus Postfire Seedlings and Resprout Recruitment by Ceanothus
These data summarize postfire resprouts and seedling counts for Ceanothus species in subgenus Ceanothus based on published data that is cited and personal observation by the author and other co-authors of the publication.
Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon Sensor data from debris-flow experiments conducted in June, 2016, at the USGS Debris-flow Flume, HJ Andrews Experimental Forest, Blue River, Oregon
These data were collected as part of a long-term program of large-scale experimentation at the USGS debris-flow flume. The chief focus of the six experiments performed in 2016 and represented in this data set was twofold: (1) measurement of evolving basal stresses as the flume headgate opened, and (2) measurement of broadband seismic energy radiated by the moving debris flows. The...
Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023 Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023
Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...
