“…The high lake level recorded in Surprise Valley at 13.93 ka occurs within error of the Chewaucan Basin stillstand (13.04 ka) to the north (Licciardi, 2001;Negrini, 2002) and after the Lake Lahontan highstand (15.22 ka) to the south (Adams and Wesnousky, 1998;Godsey et al, 2011). The data presented in this study suggests that Lake Surprise remained at a moderate lake level during the LGM, with the lake level peaking after the…”

“…The well-dated records from Lake Bonneville, Lake Lahontan, Searles Lake and Lake Surprise demonstrate this trend. Many authors have postulated a southward deflection of the jet stream and westerly storm tracks with increasing growth of the Laurentide and Cordilleran ice sheets (Negrini, 2002;Benson et al, 1990;Adams and Wesnousky, 1998;Zic et al, 2002). Interpretations of several speleothem records, such as the Cave of the Bells record (Wagner et al, 2010) presented in Figure 10 have also invoked the shifting westerly winds as the atmospheric connection between increased rainfall and increased ice sheet extent (Oster et al, 2009;Asmeron et al, 2010).…”

“…Shoreline age data constrain short-term changes in the hydrologic balance of a particular lake system. Additionally, as horizontal geomorphic features, shorelines are paleohorizontal datums that have been used to measure both brittle faulting and broad unwarping of the lithosphere (Bills and May, 1987;Adams and Wesnousky, 1998;Oldow and Singleton, 2008). However, due to subsequent erosion, isostatic rebound and eolian inputs, natural variability is often observed in shoreline deposits (Scholfield et al, 2004;Jewell, 2007;Jewell and Nicoll, 2011) and it is important to recognize these processes when interpreting elevation data.…”

“…A lake's shoreline erosional features, along with the sedimentary facies, minerals and organic materials found in lake sediment cores, record the age of lake levels and the paleoenvironmental conditions (Adams and Wesnousky, 1998;Felton et al, 2006;Godsey et al, 2011). Therefore, the timing of fluctuations during past lake cycles can be determined by dating beach deposits such as tufa (Ku et al, 1998;Garnet et al, 2004) and studying lake sediment cores (e.g.…”

Knowledge of Earth’s climate history and sensitivity, combined with modeling past and future climate, are central to informing policy decisions regarding future climate change. The hydrologic response to future warming scenarios due to increased anthropogenic CO2 emissions remains uncertain. Freshwater availability in the arid western United States is projected to decrease in availability as increased agricultural, urban and industrial uses continue to stress supplies. Motivated by the potential for dramatic future hydrologic changes, studies recording the abrupt transitions between different equilibrium states of natural past climate variability shed light on our understanding of the modern climate system.The presence of pluvial lakes in the Basin and Range Province, in the western United States, during the late Pleistocene (40 to 10 ka) indicates far greater moisture availability during the Pleistocene glacials. This study investigates the timing and magnitude of the most recent pluvial lake cycle that filled Surprise Valley, California using geophysical, geochemical and geochronologic tools. Spanning 31.2 to 4.6 ka, this new lake level record places the highest lake level, at 180 meters above present day playa, at 13.9 ± 1.2 ka. This age appears to be nearly synchronous with highstands of Lake Lahontan to the south and the Chewaucan Basin to the north. Additionally, most of the Basin and Range lake highstands, including Lake Surprise, follow peaks in precipitation minus evapotranspiration (P-ET) by 8-10 kyr. By compiling a diverse set of paleoclimate data available for western North America, I found that the timing and geographic distribution of lake highstands is inconsistent with increased precipitation in response to shifting westerly winds, the current model for the genesis of large lakes in western North America. Rather, lakes levels are more strongly correlated with changes in summer insolation, suggesting that lake highstands were likely facilitated by colder temperatures and increased humidity due to the presence of continental ice sheets and increased atmospheric convergence. I compared the constraints from lake and soil-based records to Atmosphere-Ocean General Circulation Model simulations from the Paleoclimate Model Intercomparison Project 2. Based on model-proxy intercomparison, the Atmosphere-Ocean General Circulation Models, the same models used to also assess future climatic changes, poorly predict hydrologic quantities for the Last Glacial Maximum.

Understanding fluvial adjustments to base level changes benefits the fields of sequence stratigraphy, geomorphology and petroleum geology. This investigation is a modern case study of the channel dynamics of Lee Creek and the Goggin Drain, two streams that are part of the Jordan River drainage into the endorheic Great Salt Lake of northern Utah, a lacustrine system that has experienced multiple, decadal-scale base level changes. Since 1965, the lake level has fluctuated in elevation more than 6 m, transitioning from an historic lowstand [< 1279 m above sea level (a.s.l.)] to an historic highstand (>1284 m a.s.l.), and in 2009-2010 approaching an historic lowstand. This study uses detailed aerial images, fieldwork and LiDAR data to link the modern geomorphology and channel hydraulics to specific variations in sediment transport, channel form, and avulsion behavior. Although Lee Creek and the Goggin Drain are situated only a few kilometers apart and share similar shore zone gradients, substrates and vegetation patterns, and have been subjected to the same changes in lake level, their channel forms have evolved very differently. Differences in discharge patterns are likely the most influential factor causing the meandering form of Lee Creek and the braiding channel of the Goggin Drain. Despite the differences in discharge, total sediment eroded from the two streams is comparable and can be attributed to similar stream power/unit stream width in the two streams. Although Lee Creek has not recently been avulsive, three major avulsions of the Goggin Drain have taken place since 1965. Two possible styles of avulsion are interpreted: an allogenic response to changing base level, and an autogenic response dictated by channel morphology and hydraulics. Despite a wealth of available information, avulsions cannot be unequivocally attributed to one style or another. Caution should be used when attempting to link the complex process of avulsion to causal mechanisms.
