    If you were to ask KNAU commentator Scott Thybony what his favorite Grand Canyon rock layer was, he would likely say ‘Redwall Limestone’. He developed a deep appreciation for it years ago on a long trek with his brother. The rock presents stunning, vertical walls that run miles without a break. In his latest Canyon Commentary, Scott shares the story of coming to know this imposing geological formation.
