Sedona Geology

Saturday morning we drove north on I-17 toward the Grand Canyon.  On the way, we encountered the beautiful scenery of Sedona

Sedona's famous rock formations have been created slowly for over 350 million years. The geological events of the Sedona area, from oceans and desert formation to volcanic eruptions, have all contributed to the red-rock vistas seen today. 

 

If one were to cut a 5,000-feet-high (above sea level) slice of the land of the Colorado Plateau, one would see about ten layers of sedimentary rock signifying different geological events that occurred from 330 to 7 million years ago. The formations of Sedona reveal layers ranging from 300 to 250 million years old that were originally deposited by swamps, coastal floodplains, and wind-blown red sand. The exceptional scarlet color comes from red iron-oxide stains formed when floodplain deposits of iron minerals mixed with oxygen available at the time. 

The rock formations appear today because of the rock's unusual susceptibility to erosion.  About 7 million years ago the area's layers were topped with volcanic lava and cinders, but geologic faulting helped creek waters break through the lava cap and carve today's canyons and buttes.

Sedona History

The Sedona area has been occupied by humans since about 8,000 B.C., when Paleo-Indians hunted Ice Age mammals. By 700 A.D., the Hohokam had moved into the area and introduced irrigation farming, producing crops of corn, beans, and squash. Next the Sinaguan tribe arrived, but they were forced to leave after a violent volcanic eruption in 1066 A.D. They were followed by the Anasazi, attracted by the fertile soils created by residual volcanic ash. They disappeared very suddenly in the late 1300s for unexplained reasons. 

White men arrived in the region about 1583 looking for gold. Pioneers, prospectors, and trappers began to arrive in the early 1800s, and battles with Native Americans soon ensued.  In 1876 John "Jim" Thompson built a cabin in Oak Creek Canyon, becoming the first permanent white settler.  In 1901, a Pennsylvania Dutch couple, Theodore and Sedona Schnebly, moved to the area and purchased 80 acres. "Schnebly" being too difficult a name to grace a post office, in 1902 the town was officially named after Sedona.  In 1923 the locally filmed silent movie "Call of the Canyon" became a success, and film crews began flocking to Sedona's red rock country. Hundreds of movies have been filmed there since. [At right, one of many roadside trees decorated for the holidays.]

Exploring Sedona

After taking many photographs along I-17, we stopped in downtown Sedona, walked along main street, and ate lunch on the back deck of a cafe [left]. After lunch, while Jan took in some sun, Amy and Cameron shopped for jewelry and souvenirs. 

Then we headed north up tree-lined Oak Creek Canyon, which looked more and more like the mountains of Washington State as we approached the top of the pass. We stopped at the top, where Native American artisans are allowed to sell their wares, and we purchased a beautiful Navajo vase. 

Later that day we arrived in Williams, where we stayed for two nights. For evening entertainment, we drove about 1/2 hour east to Flagstaff and saw the town's Christmas parade, replete with floats from the local Kiwanis Club, Boy Scout troop, and towing companies; specially lit cars from the Classic Car Club; and marching bands from area schools. It was charming and fun, true small-town America.
