This data release contains a dataset that depicts fault scarps along the Zapata and Blanca sections of the Sangre de Cristo fault zone located in the San Luis basin of southern Colorado. The Zapata and Blanca sections extend from the Great Sand Dunes National Park and Preserve to the Blanca Peak massif and are differentiated by a sharp change in fault zone orientation from north-south to east-west. The fault scarps are the result of Quaternary tectonic extension causing surface rupturing earthquakes estimated to have occurred most recently 8-12 ka with probable Mw 6-7 (Ruleman & Machette, 2007). The dataset represents detailed mapping of probable fault surface rupture on high-resolution (1m/pix) topographic data...
40Ar/39Ar data and ages for select bedrock volcanic samples listed in Table 1 Volcanic Rock Samples and described in Table S4 in the related manuscript. Samples collected from the Mushroom Rock region, northeastern California.
This dataset contains 40Ar/39Ar ages from the Mushroom Rock region, northeastern California, and can be found in Table 3 in the related manuscript.

This data release presents geologic map data for the surficial geology of the Aztec 1-degree by 2-degree quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains province, and the Colorado Plateau province, Navajo section. Geologic mapping is mostly compiled from published geologic map data sources ranging from 1:24,000 to 1:250,000 scale, with limited new interpretive contributions. Gaps in map compilation are related to a lack of published geologic mapping at the time of compilation, and not necessarily a lack of surficial deposits. Much of the geology incorporated from published geologic maps is adjusted based on digital elevation model and natural-color...

This dataset contains apatite and zircon U-Th(He)data, 4He/3He thermochronologic data, and apatite fission-track data from the southern Stillwater Range, Nevada
This dataset provides field observations of lineaments and scarps from the Pondosa fault zone, Mushroom Rock Region, northeastern California, and can be found in Table S6 of the related manuscript.

This dataset contains linework of lineaments mapped on 4 <1-m-resolution lidar datasets and the 10-m-resolution National Elevation Dataset digital elevation models in the Pit River region of northeastern California. Lineaments are classified by confidence in tectonic origin, map certainty, and the ages of the bedrock and surficial deposits they cross.
These datasets provide bedrock mapping and geochemistry, low-temperature thermochronology, remotely mapped lineaments, field observations of interpreted faults, and structure from motion models in the Pit River Region of northeastern California. The bedrock mapping datasets contain bedding orientations and field rock descriptions and associated geochemistry and 40Ar/39Ar data for a limited number of samples. Low-temperature thermochronology datasets contain (U-Th)/He measurements for two samples from the Klamath terranes. Remotely mapped lineaments, field observations of lineaments, and structure from motion models document the Quaternary-active faults in the region. Simplified fault traces for interpreted Quaternary-active...
This dataset contains sample locations for low-temperature thermochronology analysis, and can be found in Table 2 of the related manuscript.
Raw geochemistry data for bedrock volcanic samples listed in Table 1 Volcanic Rock Samples. Samples collected from the Mushroom Rock region, northeastern California.

With an increase in appropriations, congress recently issued a mandate to the National Cooperative Geologic Mapping Program to “bring together detailed national and continental-resolution 2D and 3D information produced throughout the Survey and by federal and state partners.” The National Geologic Synthesis project has been charged with a large portion of this task. This ScienceBase Community page is a warehouse of incrementally released components of these national maps as Data Releases. Ultimately these components will be integrated into a unified database that is served to the public.
This dataset contains point observations of bedrock (primarily volcanic rocks) orientations and field descriptions in the Mushroom Rock region, northeastern California and can be found in Table S1 of the related manuscript.
