What are the contents of the aesthetic discovery? Formal properties of beauty may be pointed to in what I saw: the verticals as distinctively shaped and gathering space about them, and the interplay between the two kinds of vertical shapes over the enormous intervening space. The pleasure of perspective entered, for though the chimney is miniscule compared to Half Dome, my approaching it from the trail made it assume visual and spatial dignity equal to the mountain. Complexity of human meaning is encountered with poignant irony. The chimney is an enduring marker of the human value placed on the mountain visible from this point. Here human hands raised stones to shelter an experience of pure stone. So I have come to the right place; I am at home. But the human occupation has been lifted; our presence has turned to stone. Nature has reclaimed its elements. Half Dome presides over the petrifaction of the world. Chimney and mountain are in dialogue as I sense the switching between their perspectives. I am present in ruin and in unity.
