The aim of this study was to construct the sequence of events that lead to the development of the Mormon Mesa soil profile, generally 4 petrocalcic soil horizons from the base upward (transitional, laminar, massive, and brecciated) and an additional set of horizons that formed in unconsolidated surficial eolian sediments. The AA. interpreted horizon characteristics and pedogenic features of 7 profiles containing stages II-VI petrocalcic horizons. This study provides a relative sequence of events for the formation of pedogenic features at Mormon Mesa that can be used for the future dating applications. The results showcase the complex geomorphic and paleoclimatic history of this geomorphic surface and help elucidate features that may be used to interpret other highly developed petrocalcic horizons worldwide
