Abstract:
This map represents the general distribution of bedrock and surficial deposits of the Bonanza 7.5' quadrangle, Klamath County, Oregon, at a scale of 1:24,000. The Bonanza quadrangle is located in the Klamath Basin approximately 21 km (13 mi) east of Klamath Falls, Oregon. Northwest-trending valleys and ridges across the quadrangle are typical of the Basin and Range geomorphic province which extends from Klamath Falls to the Wasatch Range in Utah. The easternmost extension of Horton Rim trends east-west and ends at Harpold Dam. The Lost River meanders from northeast to southwest across the quadrangle over a broad flood plain, except at Harpold Dam where it cuts a narrow gap through the juncture of the easternmost extension of Horton Rim and northwest-trending ridges. The valleys are elongate, grassy or marshy, and mostly now developed in agriculture. Alkali Lake in Yonna Valley is an enclosed basin that usually holds a shallow lake. Clays and evaporite salts are evident along the lake’s margins. The mountain ranges rise more than 274 m (900 ft) above the valley floors and are timbered mainly with juniper and sporadic Ponderosa pine and some Douglas fir found mainly on Bryant Mountain. Elevations range from about 1,249 m (4,099 ft) at the Lost River on the west edge of the quadrangle to 1,599 m (5,248 ft) on the flanks of Bryant Mountain. The Bonanza quadrangle is one of several 7.5 minute quadrangles being mapped in the Klamath Basin in conjunction with earthquake hazards and groundwater availability studies being conducted by various state and federal agencies. This mapping was funded in part under the STATEMAP program of the U.S. Geological Survey. This study has delineated faults, characterized lithologic units and rock geochemistry, and provided absolute and relative age constraints for volcanism and sedimentation. This data is crucial for adequately assessing hazard risk and mineral and hydrologic resource potential.
The oldest rocks are Miocene age tholeiitic basalt lava flows at Bryant Mountain. These rocks have been exhumed by a large-offset, high-angle normal fault on the west side of Bryant Mountain. Continental sedimentary rocks of Pliocene to Miocene age are deposited on unexposed volcanic rocks of early Pliocene and Miocene age that have been penetrated in drill holes. Lacustrine mudstones are most common in surface outcrop and drill holes, but sandstone beds and paleosols indicate fluvial and deltaic facies. Although some wells in Poe Valley penetrate as much as 230 m (750 ft) of sedimentary rocks, typically these units are thinner. Basaltic andesitic surge deposits indicate explosive water-lava interactions near the lava-sediment interface. Large volumes of primarily basaltic andesite lava from Strombolian-style eruptions have built elongate volcanic edifices that closely follow the predominant northwesterly trend of ranges and faults. Dikes, the source conduits for erupting lava, also trend mostly northwest. Most of these lava flows and their associated dikes are between 3.8 and 4.6 Ma in age. Although volcanism ended in Pliocene time, basin sedimentation, including alluvial fan development and playa lake sedimentation, and tectonic extension, with its associated seismicity, have continued to the present.
Crushed rock resources are abundant, particularly on ridges where soil development is minimal. Cinder resources are much less abundant and all surface deposits have been discovered and partly exploited. Highly transmissive basalt aquifers supply wells that produce water at rates commonly in excess of 1,000 gallons per minute (gpm) and up to more than 5,000 gpm. Wells in fine-grained sedimentary and volcaniclastic rock aquifers produce from a few tens of gpm to a couple hundred gpm.
The quadrangle lies within the seismically active Basin and Range Province. Major faults in the Klamath Falls region have historically generated Richter-magnitude 6.0 and have the potential to produce magnitude 7.3 earthquakes. There is, however, no known historical seismic activity in the quadrangle and this study did not reveal any Quaternary colluvial deposits cut by faults.

Purpose:
Any application involving the need for geologic data in the Bonanza 7.5' quadrangle, Klamath County, Oregon. This map is released as an interim product as part of an ongoing project to map the geology of the Klamath Basin, southwest Oregon.The Bonanza quadrangle is one of several 7.5-minute quadrangles being mapped in the Klamath Basin in conjunction with earthquake hazards and groundwater availability studies being conducted by various state and federal agencies. This mapping was funded in part under the STATEMAP program of the U.S. Geological Survey. This study has delineated geologic structures, including volcanic dikes, vent rocks, and faults, and characterized lithologic units and rock geochemistry, and provided absolute and relative age constraints for volcanism and sedimentation.
Supplemental Information:
Digital files include various map coverages created in MapInfo Professional version 7.0 (.tab) and a screen graphic of the map in Adobe PDF format. Also, map coverages are provided in ESRI's ArcView version 3.3 Shapefile (.shp) format. A text accompanies the digital map files (see GMS116text.pdf). This text contains a detailed map unit description, a discussion of the quadrangle's geologic history, and an assessment of the quadrangle's geologic hazards and resources. The following digital geologic map entities are provided: map_polygons and map_faults. The plotfiles (PDF format) will generate a map sheet and DOGAMI Geologic Map Series Report. The author was given digital data sets and paper plots for checking against the source map(s) to verify the linework and attributes. Also, the author was asked to check the metadata and accompanying files for completeness and accuracy. Geologic mapping for this project was accomplished by a combination of field traverses both on foot and by vehicle, visual analysis and interpretation of color infrared aerial photographs and black-and-white digital orthophotoquadrangles, and integration of petrographic thin section analyses, geochemical analyses, and isotopic age data. Geologic field mapping and sampling for this project was done over a period of five months. Robert Newman, a student from Oregon State University provided assistance. He was assigned independent mapping and sampling traverses. Contacts observed in the field could often be extended using photographic data. Subtle variations in relief are accentuated when viewed stereographically and often indicate changes in rock type beneath thinning soil cover. Field inspections on a case-by-case basis either confirmed or dispelled this notion. Poor exposure, however, due to lava rock colluvium and soil cover that are extensive on virtually all slopes, made contact delineation difficult even on foot. Rock identifications from the field were compared against petrographic and geochemical data. A review of previous literature combined with the new isotopic ages found in GMS116text.pdf helped to determine the age ranges of units.

Use Constraints:
The Bonanza 7.5' geologic-map database should be used to evaluate and understand the geologic character of the Bonanza quadrangle as a whole. The data should not be used for purposes of site-specific land-use planning or site-specific geologic evaluations. The database is sufficiently detailed to identify and characterize geologic materials and structures. However, it is not sufficiently detailed for site-specific determinations. There is uncertainity in the position of geologic contacts from the field mapping process. It may be inappropriate to use this data set at scales smaller than originally intended. The fact that this database was compiled and edited at a scale of 1:24,000 means that higher resolution information may not have been uniformly retained in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, although higher resolution data is incorporated in most of the map, the resolution of the combined output will be limited by the lower resolution data. Acknowledgment of the Department of Geology and Mineral Industries and partial funding from the U.S. Geological Survey would be appreciated in products derived from these data.

Attribute Accuracy:

Attribute Accuracy Report: Polygon and polyline entities were entered and checked by the geologist who made the observations.

Logical Consistency Report:
Note that MapInfo Professional version 7.0 cannot establish dataset topology. This version of MapInfo can check regions (polygons) for misalignment errors such as gaps (slivers), region overlaps, self intersections, and duplicate nodes. If found, these errors were corrected, followed by editing the resulting spatial dataset.
Completeness Report:
This set of digital coverages delineate the geologic features within the Bonanza 7.5' quadrangle, Klamath County, Oregon, at a scale of 1:24,000. It does not include the files used to create the information shown in collar, or margins, of the paper version and graphic versions of the complete publication. Geologic field mapping and sampling for this project was done over a period of five months concurrently with mapping of the adjacent Bonanza quadrangle and augmented by several additional months of analysis, integration, and interpretation of the data in the office. The author was assisted in the field by Robert Newman, a student of Oregon State University, through a grant from the Association of American State Geologists. Mr. Newman conducted numerous independent foot traverses as assigned, collecting samples and providing his observations. Field mapping included mapping on 7.5-minute topography sheets using observations and data collected during both foot and vehicle traverses. Contacts were located where visible or placed based upon interpretation of topography and structure. Geologic contacts and faults were also derived from stereo color infrared aerial photographs at 1:12,000-scale using a Kern PG-2 stereo plotting instrument at various magnifications. Since the PG-2 accentuates vertical relief, it is particularly useful for mapping Quaternary units, and it also allows for accurate mapping of units where subtle changes in slope angle delineate contacts. Poor exposure, however, due to lava rock colluvium (mapped in a few areas) and also soil cover on most slopes, often make contact delineation difficult. Geologic structures were also derived from USGS Digital Orthophoto Quadrangles (DOQ’s) and 10-m Digital Elevation Models (DEM’s). The DEM’s were rendered in Vertical Mapper, a software module for MapInfo, a Geographic Information System (GIS) software package.. The various geologic datasets were compared and reconciled variously on paper and in MapInfo, The geologic data collected from visual inspection of units in the field was augmented and integrated with petrographic thin section analyses of samples, new geochemical analyses and new and existing isotopic age data. Thin section analyses were performed by the author using a petrographic microscope. Geochemical analyses of rock chemistry were done using X-ray fluorescence methodology in the laboratory of Stanley A. Mertzman, Franklin and Marshall College. New isotopic ages were determined using 40Ar/39Ar methods in the laboratory of Robert A. Duncan, Oregon State University.

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report:
Users of this digital geologic map should respect the intentions of the original mapper and the limitations of the map. Geologic mapping for this project was accomplished by a combination of field traverses both on foot and by vehicle, visual analysis and interpretation of color infrared aerial photographs and black-and-white digital orthophotoquadrangles. Stratigraphic and fault contacts are accurate to ±40 feet at best. Because of colluvium that obscures most contacts, positional accuracy may be degraded as much as four to five times the best possible solution of ±40 feet. To preserve cartagraphic clarity, some structural symbols may have been moved slightly (±100 feet) from their field position. Sample positions are accurate to ±40 feet at best, but probably not worse than twice that accuracy, having been determined by altimeter and field map interpretation. Well locations were located by Oregon Water Resources Department by GPS to better than ±40 feet except where noted in the text.There is no elevation data in the database.
