We've been on the road, this time to Utah and Arizona. After a few days of camping in California we drove to St. George, Utah for a "Road Scholar" program about the geology and human history of the
Our instructor was Dan, (the one on the left) 83 years young, a retired geologist, he was determined to share his enthusiasm for the geology of his home state of Utah.
Patty, his wife, was our coordinator. It was her job to keep Dan and the rest of us in line and everything running smoothly.
They were fun, funny and young at heart.
After a morning of introduction to what we could expect they took us to Snow Canyon, named for a person, not the white stuff. At Snow Canyon Dan showed us Navajo Sandstone, a feature we would see often all over the Colorado Plateau.
This sandstone is the remnant of ancient sand dunes, much like the Sahara of today. You can see how the winds changed over time by the different direction in the patterns of the stone. We learned that this is called cross bedding. See the tiny people in the upper left? These formations are huge.
While much of the sandstone is the red we associate with the southwest in other places it is almost white but it is all Navajo sandstone.
It is just one of many layers exposed by erosion in the Colorado Plateau, here it's covered by a lava cap, protecting the sandstone from erosion.
Don't worry, I'm not going to try to give you a course in geology but I did find it added something to the trip to know what those layers of rock are.
It was a ten day course and we visited Zion, Bryce, Capitol Reef, Monument Valley, Arches, Canyonlands, Lake Powell and a few other places. Then Hubby and I continued our camping trip and went to Canyon de Chelly and Petrified forest. If you get tired of red rocks over the next few weeks, feel free to leave. I hope you'll return later, to see what our next adventure will be.
