Any visitor to Yosemite inescapably encounters granite – it is the essence of the park. Few if any know granite like Michael P. Cohen, who has climbed big walls, wandered on and around its less than vertical presences, read deeply into its geomorphology and mineralogy, and intimately explored and reflected on the nature of Yosemite granite for over a half century. Granite and Grace is a meditation on what he has come to know of it in all these ways and years.
