Soil evolution on a terrace chronosequence in the Wind River Basin, Wyoming
A series of strath terraces overlain with alluvial deposits from glacial and inter-glacial periods were used to develop a chronosequence. The sequence of soils examined in this study illustrate the effects of time on soil formation. Clay and carbonate percentages showed significant increases over time. Other indicators of soil evolution were less useful in evaluating the relationship between time and soil properties. Mineralogy characterization shows a predominance of smectite throughout the clay size fractions at each site. Chlorite, vermiculite and palygorskite are also abundant as well as ...
