Two unknown hikers on the gneiss rocks in Sabino Canyon. We saw the hikers from a higher vantage point and wondered how they got there. Walking further down the path, we found how to get where they were and let me tell you, it was even more thrilling to be standing where they are seen than seeing it from above. The photo you see below in the comments was taken of my daughter and her husband sitting in the same place as the hikers were standing. Sabino Canyon has some incredible vistas and is a geological wonder--a photographer's paradise.

Here is some information from an article in the Arizona Daily Star:

"What we know today as Sabino Canyon was the site of a whole lot of scrunching 25 million years ago.

In a geologic nutshell: Two ancient types of rock - 1.4-billion-year-old Oracle granite and 50-million-year-old wilderness granite combined to form a type of rock called gneiss.

A display in the super-scenic canyon northeast of Tucson says the granite rocks were "squeezed together and stretched like warm taffy 25 million years ago."

The resulting gneiss - pronounced "nice" - appears today as the comely striped rocks seen in canyon cliffs and some streambeds.

"The geology in Sabino Canyon is just fantastic," says Michael Conway of the Arizona Geological Survey.

"Granites are exposed. Gneiss is exposed" in canyon cliffs, Conway says. 'In streambeds, you can see massive boulders brought down from on high.'"
