“…Results from these studies underscore that a one-model-fits-all approach is not appropriate. Instead, The research reported here expands the initial work in upper Spring Creek (e.g., [1,8]) based on additional profiles, stratigraphic refinement, and an increased number of radiocarbon dates. Of the 19 localities in Conley [1] and Conley et al [2], only one (Macy Locality 10) is within the Spring Creek Valley.…”

“…The previous study of that one profile has identified a buried soil and provided a radiocarbon date from the A-horizon of the buried soil. Of the 17 localities in Murphy et al [8], only one (Macy Locality 100) is within the Spring Creek Valley. Of the one profile previously studied for Macy Locality 100, the broad depositional units then defined have been refined (e.g., current units 2 and 5 not previously identified) and the depositional mode revised.…”

“…Over the past 11 years, research activities in the uppermost reaches of Spring Creek on the eastern edge of the Southern High Plains, Texas, have identified, explored, and excavated a series of Late Pleistocene vertebrate faunal localities and Holocene archaeological sites [1][2][3][4][5][6][7][8]. In addition to faunal and cultural studies, the research effort also has involved intensive investigation of associated Spring Creek depositional patterns.…”

“…Spring Creek is part of the South Fork of the Double Mountain Fork of the Brazos River drainage and lies within the larger Post research area inside an extensive historic ranch (Figure 2). An initial overview of the sediments and soils [8] across that larger research area (a mesoscale landscape study) has pointed out: (1) Late Pleistocene and Early Holocene sediments and soils occur in the upper tributary drainages; and (2) these areas are targets for future research, particularly for locating in-situ archaeological sites. The research reported here expands the initial work in upper Spring Creek (e.g., [1,8]) based on additional profiles, stratigraphic refinement, and an increased number of radiocarbon dates.…”

The eastern escarpment breaks of the Southern High Plains of Texas are both a geomorphic and ecotonal transition zone from the high plains surface to the Rolling Plains below. The geoarchaeological record on the Southern High Plains surface is well documented, but few studies have investigated the sediments, soils, and geochronology of the eastern escarpment. The current investigation has targeted the discontinuous remnants of Late Quaternary deposits within Spring Creek, a tributary within the upper Brazos River basin. A total of 19 profiles, core, and isolated exposure locations placed along a transect from Macy Fork through upper Spring Creek and 40 radiocarbon ages provide a composite sequence and geochronology that also documents the Late Pleistocene to Late Holocene paleoenvironments of this drainage. The resulting record illustrates a series of major changes in sediments and local habitats over the past ~11,550 radiocarbon years (13,469–13,390 calendar years), characterized primarily by reductions in available water and increasing aridity that peaked during the middle Holocene. This sequence provides significant context to an expanding record of Late Pleistocene to middle Holocene biota and cultures. Subsequent downcutting of the drainage post-6000 14C yr B.P. (6988–6744 calendar years) removed large sections of the depositional sequence. Local topography within Spring Creek drainage greatly impacted the preservation of these deposits. The remaining record provides some different insights than those available from the Southern High Plains record.
