Photo: Some Moenkope, right about where it got folded over by the impact.
Photo: Some of Barringer's old mining apparatus--here, he was going for “rockflour,” which is quartz sandstone that got shock-metamorphosed in such a way that the grains were pulverized in place. The rockflour is incredibly fine, but preserves Coconino features like crossbeds.
