The Summer Lake basin in south-central Oregon lies within the north-western Basin and Range (NWBR), an active low-strain rate region with no historic large earthquakes. However, high-resolution topographic maps derived from LiDAR data highlight fault scarps along all of the major faults in the basin. Detailed mapping and topographic analysis of fau...

Development of strong interdisciplinary curricular materials requires bringing together teams of instructors with diverse disciplinary expertise around complex and compelling topics. Many faculty lack the experience and support needed to effectively develop curricula as part of a team. To address these needs and to meet its own goal of engaging stu...

Society faces many challenges related to its long-term sustainability and resilience of the life-support system upon which Earth depends. Developing solutions to these grand challenges requires an interdisciplinary approach that demands scientific investigation of the interactions of the geological, biological, chemical, and physical environments,...

We designed and tested a curriculum development and auditing methodology for the Interdisciplinary Teaching about Earth for a Sustainable Future (InTeGrate) project. That process was driven and facilitated by a written rubric for curriculum development. Materials developers participated in workshops to prepare them to write and revise their materia...

Interdisciplinary Teaching about the Earth and Environment for a Sustainable Future presents the outcomes of the InTeGrate project, a community effort funded by the National Science Foundation to improve Earth literacy and build a workforce prepared to tackle environmental and resource issues. The InTeGrate community is built around the shared goal...

The Basin and Range hosted large pluvial lakes during the Pleistocene, which generally reached highstands following the Last Glacial Maximum and then regressed rapidly to near-modern levels. These lakes were large and deep enough to profoundly affect the crust through flexure; they filled basins formed by faults, and they locally modified pore pres...

What is the process by which future generations are imbued with the knowledge they need to tackle the modern world’s most critical issues? Observation of the natural world should influence and shape how governments ensure the security of their citizens by incorporating hazard planning and preparation into their policies. But where are these policy...

The Next Generation Science Standards (NGSS) emphasize how human activities affect the Earth and how Earth processes impact humans, placing the concept of sustainability within the Earth and Space Sciences. We ask: how prepared are future teachers to address sustainability and systems thinking as encoded in the NGSS? And how can geoscientists suppo...

Shorelines from terminal basins provide evidence for large hydroclimate changes during Pleistocene glacial periods in the Basin and Range. Well-dated lake hydrographs provide direct evidence for regional changes in water balance over glacial-interglacial cycles. The shoreline sequences left by Pleistocene Lake Surprise range from ~50 to 200 m above...

The Basin and Range extensional province hosted large pluvial lakes during the Pleistocene, which generally reached highstands following the Last Glacial Maximum and then regressed rapidly to modern or near-modern levels. These lakes were large and deep enough to profoundly affect the crust through flexure; they filled basins formed by normal fault...

The Summer Lake basin in the northwestern Basin and Range is bounded by the active 59-km-long Winter Rim Fault (WRF) system, which includes Holocene fault scarps that cut and offset Quaternary units. The slip rate and seismic hazard for the WRF system is poorly constrained. The Winter Rim Fault System comprises four segments: Winter Ridge, Ana Rive...

The relative contributions of tectonic and magmatic processes to continental rifting are highly variable. Magnetic, gravity, and seismic reflection data from Surprise Valley, California, in the northwest Basin and Range, reveal an intrabasin, fault-controlled, ~10-m-thick dike at a depth of ~150 m, providing an excellent example of the interplay be...

Proceedings of the 26th Pacific Climate Workshop (March 3–6, 2013)

Widespread late Pleistocene lake systems of the Basin and Range Province indicate substantially greater moisture availability during glacial periods relative to modern times, but the climatic factors that drive changes in lake levels are poorly constrained. To better constrain these climatic forcing factors, we present a new lacustrine paleoclimate...

Faults and fractures play an important role in the circulation of geothermal fluids in the crust, and the nature of that role varies according to structural setting and state of stress. As a result, detailed geologic and geophysical mapping that relates thermal springs to known structural features is essential to modeling geothermal systems. Publis...

Evidence of late Pleistocene lakes in the Great Basin indicates greater moisture availability during Pleistocene glacial periods. We dated shoreline tufa deposits from wave-cut lake terraces in Surprise Valley, California to determine the hydrography of the most recent lake cycle. To further evaluate the climatic forcings associated with the lake c...

Motivated by the potential for dramatic future hydrologic changes, studies that investigate the transitions between Earth's different climate states have the potential to enhance our understanding of the modern climate system and potential future variability. The interval surrounding the Last Glacial Maximum (LGM) represents a period when Earth's b...

The Warner Range in northeastern California exposes a section of Tertiary rocks over 3 km thick, offering a unique opportunity to study the long-term history of Cascade arc volcanism in an area otherwise coveredby younger volcanic rocks. The oldest locally sourced volcanic rocks in the Warner Range are Oligocene (28-24 Ma) and include a sequence of...

Along the northwestern margin of the Basin and Range province, mid-Miocene to Pliocene volcanic rocks cover and obscure much of the earlier history of the region. In northeastern California, however, slip on the Surprise Valley fault has resulted in the uplift of the Warner Range, exposing >4 km of volcaniclastic and volcanic rocks as old as late E...

Surprise Valley, located in the northeast corner of California, constitutes the westernmost basin of the Basin and Range Province (BRP) and acts as a transition zone between the unextended Cenozoic volcanic rocks of the Modoc Plateau to the west and the extended BRP to the east. Previous seismic experiments undertaken in Surprise Valley to examine...

The Grouse Creek-Albion-Raft River metamorphic core complex in northwestern Utah and southern Idaho is characterized by several Tertiary plutons with a range of ages and crosscutting relations that help constrain the timing of extensional deformation. In the Grouse Creek Mountains, at least three distinct, superimposed, extension-related Tertiary d...

Seismic reflection profiling demonstrates that the active, significant-offset Surprise Valley Fault that marks the western boundary of the Basin-and-Range Province in northernmost California dips at a moderate angle, only ~ 30° to ~ 2 km depth. A nearby seismic refraction/wide-angle reflection profile, albeit of lower-resolution, shows the fault-pl...

Surprise Valley in northeastern California offers an ideal opportunity to examine the structural setting of a developing extensional basin due to its late Miocene to recent activity in isolation from other major normal fault-bound basins. Seismic velocity and potential field modeling help determine the nature of basin fill and identify intra-basin...

New audiomagnetotelluric (AMT), gravity, and magnetic data were collected in Surprise Valley, northwestern Basin and Range, in order to investigate the role that the Lake City Fault Zone (LCFZ) may play in controlling geothermal circulation in the area. Surprise Valley hosts an extensional geothermal system currently undergoing exploration for deve...

A thick sequence of uppermost Eocene to lower Oligocene volcaniclastic and sedimentary rocks is exposed at the base of the Warner Range in northeastern California. This isolated exposure provides insight into the palaeogeographic setting of the northwestern Basin and Range during this time period. Significant thinning of the unit over 35 km of late...

New magnetic and seismic surveys investigate a subsurface structure in eastern Surprise Valley, NE California, that may have significance to both the geothermal system and the mode of accommodation of extension across the valley. Surprise Valley is located in the transition zone between unextended Cenozoic volcanic rocks of the Modoc Plateau to the...

Introductory undergraduate courses play a pivotal role in the geosciences. They serve as recruiting grounds for majors and future professionals, provide relevant experiences in geoscience for pre-service teachers, and offer opportunities to influence future policy makers, business people, professionals, and citizens. An introductory course is also...

Despite a lack of large historical earthquakes, the Surprise Valley fault system in northeastern California is presumed to be seismically active based on the presence of numerous Holocene fault scarps and a fault- controlled geothermal system. The Surprise Valley fault is believed to be similar to historically active basin and range faults such as...

The Warner Range in northeastern California exposes over 3 km of Tertiary rocks and offers a unique opportunity to study the long-term history of Cascade arc volcanism in an area typically covered by younger lavas. The oldest locally-sourced volcanic rocks in the Warner Range are Oligocene (26-30 Ma) and include a sequence of basalt and basaltic an...

Undergraduate students hold many misconceptions about the nature and process of science, including the social and cultural components of the scientific endeavor. These misconceptions are perhaps even more pronounced in the geosciences, where most students enter college without having been exposed to subject matter in high school. Many faculty and t...

The central section of the Surprise Valley, NE California, in the westernmost section of the Basin and Range province contains a geothermal system related to extensional tectonics. Most geophysical research related to this geothermal system has focused primarily on the Lake City hot springs. Our work includes several other hot springs within the va...

Combined geological and geophysical investigations are used to characterize intra-basin and basin-bounding faults, constrain basin geometry, study fault interactions, and ultimately to identify areas favorable to hydrothermal flow in the geothermal system in Surprise Valley, California. We utilize high-resolution gravity and ground-magnetometer dat...

The Warner Range is a major west-tilted fault block in northeastern California bound on its eastern side by the Surprise Valley normal fault system, which has accommodated a minimum of 3 km of uplift. The fault system separates the northeastern Basin and Range Province on the east, which has undergone 10-15% extension since the Miocene, from the Mo...

Geology is a difficult subject to communicate effectively. Many people associate geology with memorizing rock and mineral names and not with dynamic earth processes. Even more challenging for the non-geologist is the concept of deep time, and why processes that happened millions of years ago are important to us today. Additionally, many people view...

Leland Stanford (president of the Central Pacific Railroad and former governor of California) and his wife Jane established Stanford University in 1885 as a memorial to their only child, Leland Jr., who died from typhoid fever contracted while vacationing in Florence in 1884. In 1906, fifteen years after opening, the university had just completed a...

The general public holds many misconceptions about the geosciences. Often, people confuse geologists with archaeologists, or believe geoscience careers are limited to petroleum and/or mineral exploration. People in resource-rich areas may have had only negative experiences with geoscientists, where resource extraction has come at the expense of qua...

A guided inquiry exercise has been developed to help teach the geology of the U.S. This exercise is intended for use early in the school term when undergraduate students have little background knowledge of geology. Before beginning, students should be introduced to rock types and have a basic understanding of geologic time. This exercise uses three...
