This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range. Data consist of spotted frog counts aggregated by date, location, and life stage, as well as data on environmental conditions at the time of each survey.

This digital dataset, compiled from previously published andunpublished data sources, contains a personal geodatabase andraster data of features related to the repeated inundation of theWillamette Valley and Portland basin by Missoula Flood waters inLate Pleistocene time. The feature classes contained within theWill_Valley geodatabase are called 'erratics', representing thelocations of ice-rafted erratics; 'contours', representinginundation levels associated with stratigraphic evidence ofrepeated floodings; and 'geology', representing the generaldistribution of Missoula Flood deposits. A stand-alone tablewithin the geodatabase contains geologic unit descriptions forthe geology polygons contained in the 'geology'...

Forests in Washington State generate substantial economic revenue from commercial timber harvesting on private lands. To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the central Cascade Mountain area, we relied on a new generation of annual land-use/land-cover (LULC) products created from the application of the Continuous Change Detection and Classification (CCDC) algorithm to Landsat satellite imagery collected from 1985 to 2014. We calculated metrics of landscape pattern using patches of intact and harvested forest patches identified in each annual layer to identify changes throughout the time series. Patch dynamics revealed four distinct eras...
Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/2015WR017873/abstract): Spatially distributed snow depth and snow duration data were collected over two to four snow seasons during water years 2011–2014 in experimental forest plots within the Cedar River Municipal Watershed, 50 km east of Seattle, Washington, USA. These 40 × 40 m forest plots, situated on the western slope of the Cascade Range, include unthinned second-growth coniferous forests, variable density thinned forests, forest gaps in which a 20 m diameter (approximately equivalent to one tree height) gap was cut in the middle of each plot, and old-growth forest. Together, this publicly available data set includes snow depth and density observations...

This dataset contains information from surveys conducted 2010-2018 by USGS as part of a long-term Oregon spotted frog monitoring effort in the central Oregon range. Data consist of site, survey, habitat, and species detection covariates, as well as inter-site distance measurements.
The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. During 2017, U.S. Forest Service contracted the acquisitions of airborne lidar surveys of Mount St. Helens and upper North Fork Toutle River basin, part of a larger 2017-2018 survey of the Gifford Pinchot National Forest. The U.S. Geological Survey combined and reprojected 81 raster datasets, provided by the U.S. Forest Service in October 2018, into a single digital elevation model (DEM) of the ground surface, including beneath forest cover (that is, 'bare earth')....

This dataset contains information from capture-mark-recapture sampling of Oregon spotted frogs (Rana pretiosa) conducted 2016-2019 by USGS as part of a study relating R. pretiosa survival and abundance to wetland inundation in the upper Deschutes River. Data consist of site, survey, habitat, and species detection covariates, as well as 10 years of hydrological and drought metrics used to establish relationships between river flow and area of inundation at survey sites. Remotely sensed and model predicted area wet estimates for the sites are also given.

This digital dataset was compiled from newly released U.S.Geological Survey 10-meter digital elevation model (DEM) data,along with stream and transportation coverages previouslypublished on the internet. This report consists of a digitalrepresentation of the physiography of the Willamette Valley.Contained in this dataset is: 1) 10-meter DEM data for the entireWillamette Valley; 2) the ARC/INFO grids used to create the colorshaded-relief and gray scale shaded-relief images; 3) thenecessary data ARC/INFO data to used to plot these data; and 4)several reports detailing the data formats (this docuement) andproducers used to create these datasets. The scale of theoriginal 10-meter DEM data should not be violated. Any...
Hydrothermal heat discharge in the Cascade Range includes the heat discharged by thermal springs, by “slightly thermal” springs that are only a few degrees warmer than ambient temperature, and by fumaroles. Thermal-spring heat discharge is calculated on the basis of chloride-flux measurements and geothermometer temperatures and totals ~ 240 MW in the U.S. part of the Cascade Range, excluding the transient post-1980 discharge at Mount St. Helens (~ 80 MW as of 2004–5). Heat discharge from “slightly thermal” springs is based on the degree of geothermal warming (after correction for gravitational potential energy effects) and totals ~ 660 MW. Fumarolic heat discharge is calculated by a variety of indirect and direct...

This study quantifies the cycling of halogen elements through the Cascadia subduction zone based on the chemistry of thermal springs in the Central Oregon Cascade Range and of a mineral spring in the forearc (Willamette Valley). Considerations based on mass balances, element ratios, and 36Cl/Cl and 129I/I ratios suggest that halogens discharged through the thermal springs in the Cascade Range are probably derived from magma degassing. Our results indicate that < 35% of the subducted Cl and < 20% of the subducted Br and I could be transported through arc volcanism and the thermal springs, a considerably lower percentage than estimated for other volcanic arcs along the Pacific Rim. A likely explanation for this difference...

The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. The eruption produced mudflows in the South Fork Toutle River basin, which drains the western slopes of the volcano. Orthophotography was acquired shortly after the eruption (June 19 and July 1). Survey extent includes South Fork Toutle River, from its headwaters at Talas and Toutle Glaciers to its mouth at the confluence with North Fork Toutle River near Toutle, Washington. In 2004, Photo Sciences, Inc., under contract to the U.S. Geological Survey (USGS), used softcopy photogrammetry techniques to produce a contour map, breaklines, and masspoints. A USGS...

These data were compiled to allow examination of northern spotted owl territorial occupancy dynamics, especially with regards to the roles played by habitat and competition with barred owl in past and future dynamics. Data are estimates of parameters derived from previous modelling of northern spotted owl territorial occupancy dynamics. These data were collected as part of monitoring of northern spotted owl demography. Associated code allows analysis of these estimates to understand the roles of competition and habitat in recent northern spotted owl declines and to predict the future of northern spotted owl under various management scenarios.

This dataset contains information from surveys conducted 2016-2022 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities 2016-2022 were divided into seven study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, water quality (skin microbiome swabbing), and genetics (egg mass embryo or toe-clip tissue samples). Data consist of Oregon spotted frog observations aggregated by date, location, life stage, sex, and project. These data were compiled from multiple studies employing different survey methods, thus we caution users that counts are not directly...
