Shoreline altitudes of several pluvial lakes in the western Great Basin of North America record successively smaller lakes from the early to the late Pleistocene. This decrease in lake size indicates a long-term drying trend in the regional climate that is not seen in global marine oxygen-isotope records. At ؉70 m above its late Pleistocene shoreline, Lake Lahontan in the early middle Pleistocene submerged some basins previously thought to have been isolated. Other basins known to contain records of older pluvial lakes that exceeded late Pleistocene levels include Columbus-Fish Lake (Lake Columbus-Rennie), Kobeh-Diamond (Lakes Jonathan and Diamond), Newark, Long (Lake Hubbs), and Clover. Very high stands of some of these lakes probably triggered overflows of previously internally drained basins, adding to the size of Lake Lahontan. Simple calculations based on differences in lake area suggest that the highest levels of these pluvial lakes required a regional increase in effective moisture by a factor of 1.2 to 3 relative to late Pleistocene pluvial amounts (assuming that effective moisture is directly proportional to the hydrologic index, or lake area/tributary basin area). These previously unknown lake levels reflect significant changes in climate, tectonics, and (or) drainage-basin configurations, and could have facilitated migration of aquatic species in the Great Basin.

Abstract.A volcanic record of geomagnetic field inclination for the past ~400 kyr at Hilo, Hawaii, has been obtained from the 941.5 m of core recovered by the Hawaii Scientific Drilling Project. The analysis of 195 lava flows reveals six instances of near-zero inclination and two instances of fully negative inclination (reverse polarity) within an otherwise normal -polarity core. In particular, flow unit 23 (~178 m depth) records a horizontal inclination and may be associated with the Laschamp event; flow units 40 and 42 (~260 m depth) record negative inclinations and are close in age to the Blake event; and flow unit 55 (~320 m depth) records a negative inclination with a relative declination change of ~75° with respect to the overlying flow and is probably the Jamaica/Biwa I/Pringle Falls event. The five instances of shallow inclination found below 400 m depth appear to have resulted from long-term secular variation as they are part of inclination swings between ~0° and ~60° with a periodicity of ~10-50 kyr. In contrast, the inclination shifts at ~178 m and ~320 m depths significantly deviate from long-term trends, suggesting the existence of at least two independent processes producing time variations of the geomagnetic field. The secular variation has a mean of 30.9° (α 95 = 2.27°), which is significantly shallower than the expected dipole mean of 36°. The dispersion (σ = 12.5°) agrees with global paleosecular variation data for 0-5 Ma and secular variation models.

“…The ridge separates the northern and southern basins of the lake, which differ in hydrology and water chemistry. A thick layer of mirabilite occurs beneath the northern basin and is thought to have been deposited as the lake rapidly fell from the Provo level (Eardley, 1962;Eardley et al, 1973;Spencer et al, 1984). Seismic profiles near cores in which mirabilite was found exhibit an acoustically transparent layer about 2 m thick (Fig.…”

“…Sediment cores obtained from the lake, first by Eardley et al (1973), and later by Spencer et al (1984), have been supplemented by a new set of cores taken in conjunction with this study in 1995 and 1996 (Kelts, K.R., Thompson, R.S., and Oviatt, C.G., unpublished data). The geometric and stratigraphic information in our seismic data can be correlated with the chronologic and lithologic data from sediment cores located near our survey lines (Fig.…”

“…Paleoenvironmental reconstructions based mostly on paleontology and sedimentology of cuttings from three of those drill holes have been published recently by Davis and Moutoux (1998) and Kowalewska and Cohen (1998). A series of cores in the lake and cores from drill holes on the southern margin of the lake were described by Eardley et al (1973). Finally, as part of our study, several piston cores were collected in the southern Fig.…”

High-resolution seismic-reflection data from Great Salt Lake show that the basinal sediment sequence is cut by numerous faults with N -S and NE -SW orientations. This faulting shows evidence of varied timing and relative offsets, but includes at least three events totaling about 12 m following the Bonneville phase of the lake (since about 13.5 ka). Several faults displace the uppermost sediments and the lake floor. Bioherm structures are present above some faults, which suggests that the faults served as conduits for sublacustrine discharge of fresh water. A shallow, fault-controlled ridge between Carrington Island and Promontory Point, underlain by a well-cemented pavement, separates the main lake into two basins. The pavement appears to be early Holocene in age and younger sediments lap onto it. Onlap -offlap relationships, reflection truncations, and morphology of the lake floor indicate a low lake, well below the present level, during the early Holocene, during which most of the basin was probably a playa. This low stand is represented by irregular reflections in seismic profiles from the deepest part of the basin. Other prominent reflectors in the profiles are correlated with lithologic changes in sediment cores related to the end of the Bonneville stage of the lake, a thick mirabilite layer in the northern basin, and the Mazama tephra. Reflections below those penetrated by sediment cores document earlier lacustrine cycles. D
