Schist is a textural term, meaning that the rock shows foliation -- a way of splitting along planes, which are usually somewhat wavy and discontinuous.  Many times schist has sort of a glistening or shiny look.  There are many places around Phoenix and Scottsdale where one can find schist.
   It is a metamorphic rock, meaning that is has been changed by heat and pressure from its previous form, usually a sedimentary rock.  The heat and pressure were responsible for its "new" look.
   The road cut on the Squaw Peak Freeway, SR51, cutting through the Squaw Peak area, is a good place to see big outcrops of schist.
