The Cockscomb formed along the steeply tilted sedimentary layers of a geologic feature known as the East Kaibab monocline. Faulting and erosion have shaped the tilted Jurassic and Cretaceous-age rocks into the spectacular “rooster’s comb” features seen today along Cottonwood Canyon Road.

Morning sunlight illuminates water-sculpted walls of the Buckskin Gulch slot canyon. Cut deeply into Jurassic-age Navajo Sandstone, the Buckskin’s slot ranges from 5 to 25 feet wide and 100 to 500 feet high for 12 miles, making it the longest slot canyon in the world.
Powerful and turbulent flash floods carved this convoluted slot canyon into the Jurassic-age Navajo Sandstone along Willis Creek. Differential weathering of alternating weak and more resistant sandstone layers formed the horizontal grooves etched into the canyon’s walls.
Today’s photo comes from our Facebook user Dustin Garrett along with a question he asked some months ago. “Kodachrome Basin Lightning Strike – Is that indeed, what the lines are?” The lightning-shaped mineral veins are, sadly, not the result of actual lightning. They are most likely gypsum veins, which would have formed in the surrounding rock long before erosion exposed them. While fascinating in their own right, real lightning might have been a little cooler. Thanks for the question Dustin!
As an interesting side note, Kodachrome Flat was named so by the National Geographic Society in 1948 after the new brand of Kodak film which was used to photograph the area. A few years after the area became a state park in 1962 the name was changed to Kodachrome Basin with permission from Kodak.
