On Sunday afternoon I went out with Keith Minor to a North Texas site exposing the lower Arcadia Park formation and (possibly?) the top of the Britton Formation (lower Turonian, upper Cenomanian respectively). The hunt almost never happened after various storm cells were menacing us and the high winds were thrusting cranes into sky scrapers and whipping up emphysema inducing dust clouds. Yet, even though everyone around us was getting Kansas blown at them, we were only exposed to the high winds and rain so cold and blown so hard that it felt almost like hail. But that lasted for only a few minutes, leaving the rest of the day to muck around in the Turonian while the winds blew most of the clouds away by hunt’s end. The Kamp Ranch Limestone is exposed very nicely at the site, as well as meters of shale beds above and below it, making a short study of the successive stratification obligatory. FIG 1: The roughly 38 cm (15 inch) thick Kamp Ranch jutting out amongst the soft shale and clay above and below it. The clouds foretell the showers to befall us. (ID request incoming)
