Leonard Rockshelter Revisited
Robert Heizer excavated Leonard Rockshelter (26Pe14) in western Nevada more than 70 years ago. He described stratified cultural deposits spanning the Holocene. He also reported obsidian flakes purportedly associated with late Pleistocene sediments, suggesting that human use extended even farther back in time. Because Heizer never produced a final report, Leonard Rockshelter faded into obscurity despite the possibility that it might contain a Clov…
Late Holocene paleohydrology of Walker Lake and the Carson Sink in the western Great Basin, Nevada, USA
The late Holocene histories of Walker Lake and the Carson Sink were reconstructed by synthesizing existing data in both basins along with new age constraints from key sites, supplemented with paleohydrologic modeling. The repeated diversions of the Walker River to the Carson Sink and then back to Walker Lake caused Walker Lake–level fluctuations spanning ± 50 m. Low lake levels at about 1000, 750, and 300 cal yr BP are time correlative to the age…
Late Pleistocene to present lake-level fluctuations at Pyramid and Winnemucca lakes, Nevada, USA
A new lake-level curve for Pyramid and Winnemucca lakes, Nevada, is presented that indicates that after the ~15,500 cal yr BP Lake Lahontan high stand (1338 m), lake level fell to an elevation below 1200 m, before rising to 1230 m at the 12,000 cal yr BP Younger Dryas high stand. Lake level then fell to 1155 m by ~10,500 cal yr BP followed by a rise to 1200 m around 8000 cal yr BP. During the mid-Holocene, levels were relatively low (~1155 m) bef…
A First Look at the Terminal Pleistocene/Early Holocene Record of Guano Valley, Oregon, USA
Surface sites play a vital role in interpreting terminal Pleistocene/early Holocene (TP/EH) lifeways in the Great Basin. Two years of work in Oregon’s Guano Valley by crews from the University of Nevada, Reno have revealed a rich record of Western Stemmed Tradition occupations associated with an extensive delta system that brought freshwater into the valley from the adjacent tablelands. To date, we have recorded nearly 700 diagnostic TP/EH artifa…
Hydrologic fluctuations at Pyramid Lake, Walker Lake, and the Carson Sink, Nevada during the Medieval Climate Anomaly
Chronostratigraphy and lake-level changes of Laguna Cari-Laufquén, Río Negro, Argentina
Evidence from shoreline and deep-lake sediments show Laguna Cari-Laufquén, located at 41°S in central Argentina, rose and fell repeatedly during the late Quaternary. Our results show that a deep (> 38 m above modern lake level) lake persisted from no later than 28 ka to 19 ka, with the deepest lake phase from 27 to 22 ka. No evidence of highstands is found after 19 ka until the lake rose briefly in the last millennia to 12 m above the modern lake…
Climate, environment, and humans in North America’s Great Basin during the Younger Dryas, 12,900–11,600 calendar years ago
Lake Levels and Sedimentary Environments During Deposition of the Trego Hot Springs and Wono Tephras in the Lake Lahontan Basin, Nevada, USA
The Wono and Trego Hot Springs (THS) tephras are widespread in the Lahontan basin and have been identified in a variety of sedimentary environments at different elevations. Davis (1983) reported lake level to be at about 1256 m when the THS tephra was deposited, an interpretation questioned by Benson et al. (1997) who interpreted lake level to be ≤1177 m at that time. This is a significant difference in lake size with important implications for i…
Late Pleistocene and Early Holocene lake‐level fluctuations in the Lahontan Basin, Nevada
The Great Basin of the western U.S. contains a rich record of Late Pleistocene and Holocene lake‐level fluctuations as well as an extensive record of human occupation during the same time frame. We compare spatial‐temporal relationships between these records in the Lahontan basin to consider whether lake‐level fluctuations across the Pleistocene‐Holocene transition controlled distribution of archaeological sites. We use the reasonably well‐dated …
Late Pleistocene and Late Holocene Lake Highstands in the Pyramid Lake Subbasin of Lake Lahontan, Nevada, USA
Shoreline geomorphology, shoreline stratigraphy, and radiocarbon dates of organic material incorporated in constructional beach ridges record large lakes during the late Pleistocene and late Holocene in the Pyramid Lake subbasin of Lake Lahontan, Nevada, USA. During the late Holocene, a transgression began at or after 3595 ± 35 14 C yr B.P. and continued, perhaps in pulses, through 2635 ± 40 14 C yr B.P., resulting in a lake as high as 1199 m. Du…
Age and paleoclimatic significance of late Holocene lakes in the Carson Sink, NV, USA
New dating in the Carson Sink at the termini of the Humboldt and Carson rivers in the Great Basin of the western United States indicates that lakes reached elevations of 1204 and 1198 m between 915 and 652 and between 1519 and 1308 cal yr B.P., respectively. These dates confirm Morrison's original interpretation ( Lake Lahontan: Geology of the Southern Carson Desert, Professional Paper 40, U.S. Geol. Survey, 1964) that these shorelines are late H…
Obsidian-hydration dating of fluvially reworked sediments in the West Yellowstone region, Montana
This study evaluates obsidian-hydration dating in postglacial fluvial terraces cut into an outwash plain near West Yellowstone, Montana. Fluvial transport fractures obsidian grains. However, some old hydration rinds may be preserved, thus, a grain may record several fracturing events. The most recent fracturing event at West Yellowstone is recorded in surface sediments from all of the terraces, which were cut in a shorter period of time than the …
