In Mosaic Canyon, much of this marble is derived from units such as the Noonday Dolomite and overlying limestones, later metamorphosed under low- to moderate-grade conditions to produce a recrystallized, interlocking calcite texture. The rock commonly preserves subtle banding, stylolites, and pressure-solution features, and locally records minor deformation. The canyon’s distinctive smooth, polished, and fluted walls are the result of sediment-laden flash floods that have sculpted the marble surfaces. Overall, the marble records a history of marine deposition, metamorphism, and tectonic exhumation, followed by ongoing surface erosion (Mike Smith, Class of 1999, personal communication).
