After lunch we went on a guided geology tour where we learnt more about the rock formation at Bryce. The Canyon stands at the edge of the Paunsaugant Plateau on the northern edge of the Grand Staircase, a huge collection of steps in the landscape of the Colorado Plateau leading down to the Grand Canyon. The rock at Bryce is known as the Claron Formation, a collection of  limestone, silts and mudstone, sometimes topped with a layer of dolomitic limestone which is much harder than normal limestone and resilient to acid rain. The plateau edge is being continually eroded, mainly by frost damage but also by water flow off the edge of the canyon and is receding at a rate
