Reply to Skousen and Aiuvalasit
Skousen and Aiuvalasit critique our article on the post-Mississippian occupation of the Horseshoe Lake watershed (White et al. 2020) along two lines: (1) that our findings are not supported due to a lack of archaeological evidence, and (2) that we do not consider alternative hypotheses in explaining the lake's fecal stanol record. We first respond to the matter of fecal stanol deposition in Horseshoe Lake and then address the larger issue, the pr…
After Cahokia
The occupation history of the Cahokia archaeological complex (ca. AD 1050-1400) has received significant academic attention for decades, but the subsequent repopulation of the region by indigenous peoples is poorly understood. This study presents demographic trends from a fecal stanol population reconstruction of Horseshoe Lake, Illinois, along with information from archaeological, historical, and environmental sources to provide an interpretatio…
An evaluation of fecal stanols as indicators of population change at Cahokia, Illinois
Climate frequencies of the early Holocene from Foy Lake, Montana
Geochemical evidence for hydroclimatic variability over the last 2460 years from Crevice Lake in Yellowstone National Park, USA
A 2200-yr record of hydrologic variability from Foy Lake, Montana, USA, inferred from diatom and geochemical data
A 2200-yr long, high-resolution (∼5 yr) record of drought variability in northwest Montana is inferred from diatoms and δ 18 O values of bio-induced carbonate preserved in a varved lacustrine core from Foy Lake. A previously developed model of the diatom response to lake-level fluctuations is used to constrain estimates of paleolake levels derived from the diatom data. High-frequency (decadal) fluctuations in the de-trended δ 18 O record mirror v…
Timing of Atmospheric Precipitation in the Zagros Mountains Inferred from a Multi-Proxy Record from Lake Mirabad, Iran
A sediment core 7.2 m long from Lake Mirabad, Iran, was examined for loss-on-ignition, mineralogy, oxygen-isotopic composition of authigenic calcite, and trace-element composition of ostracodes to complement earlier pollen and ostracode-assemblage studies. Pollen, ostracode-inferred lake level, and high Sr/Ca ratios indicate that the early Holocene (10000 to 6500 cal yr BP) was drier than the late Holocene. Low δ 18 O values during this interval …
Evironmental change in southwestern Iran
Ostracod faunal data are presented from a sediment core taken from extant Iranian Lake Mirabad. Ostracod faunal successions indicate relatively high concentrations of mainly nektonic taxa between c. 9265 and 6505 cal. 14C yr BP, followed by lower concentrations of mainly benthic forms after 6505 cal.BP. These results suggest that lake levels were low during the early Holocene, and that water levels rose during mid- Holocene times, notably after c…
