Gray time-series and thin section images through Pueblo cultural stages. (A) The thin section image shows the first cluster of aragonite (dark) layers after 1300 yr B2K illustrating the onset of drier conditions going into the Pueblo period. (B) Pueblo II is defined by closely spaced aragonite layers and ends with a thick aragonite layer and terminal growth hiatus. (C) Thin section image shows Pueblo III starting as calcite growth and transitioning to numerous more evenly spaced aragonite layers. (D) Pueblo IV consists of mostly thick aragonite layers and the period ends in a lengthy growth hiatus.
