Did you know that Bryce Canyon is geologically part of the
Grand Staircase—the same staircase that is part of the Escalante-Grand Staircase National
Monument? Until recently, I didn't realize how all three of our National Parks,
Bryce Canyon, Zion Park, and the Grand Canyon are connected and relate to the
the Grand Staircase National Monument.
The basic explanation is that Bryce
Canyon is at the top of the staircase. Its floor is about the same strata as
the top of Zion Canyon. Zion Canyon’s floor is about the strata of the rim of
the Grand Canyon making a set of giant geological steps.
More specifically, the steps are defined by the age and
color of the rocks. When you visit these canyons, take particular note of the
color of the cliffs. The youngest rocks (which are the uppermost rocks ie.
Bryce Canyon) are the Pink Cliffs then the Grey Cliffs, White Cliffs,
Vermillion Cliffs, and Chocolate Cliffs. One of the fascinating parts of going to
the canyons is that you see more than one layer at a time just like someone
took a big slice out of a cake.
There are great resources on the web with more technical and
specific information about the Grand staircase geology. (see below) I find the
pictures and diagrams fascinating. For instance, look at the first figure.
Locate Zion Canyon and then notice how it cuts down through several strata
reaching down almost to the rim layer of the Grand Canyon. (Click here for a larger image.)
This second figure is a little more basic but still
interesting and emphasizes a little bit more the geologic relationship between Bryce, Zion and Grand Canyon National Parks.
And finally the photo taken at the Escalante-Grand Staircase
National Monument that shows the different steps.
Take a day trip. Visit Zion (or one of the other parks) look at
the different colors of rock formations and know that they represent thousands
and thousands of years in the diffence of their ages. I’m so grateful to live
in such an awe inspiring area. Click around on some of these links and learn
the nitty gritty of the earth around us.
