How does N. Scott Momaday use imagery in The Ancient Child?

Example of Imagery (Auditory, Tactile, Visual)

In the distance there were the voices of children. The air was very still. Paulita Maxwell, Pete's eighteen-year-old sister, did not weep, could not, though her heart was breaking. She kept to the darkness, her eyes open wide, as if to see something there take shape, the invisible become visible. She felt her skin tighten and become as hard and brittle as pottery. She believed that if someone should touch her she would shatter.
