Sierpinski Tetrahedra in Oak Creek Canyon in Autumn





Click to enlarge Click to enlarge

These are two of many images I took from a big Lookout Point that oversees Oak Creek Canyon. The sun was high and harsh when they were taken. The winding road visible in the picture to the right shows Scenic Highway 89A along a section of the Switchbacks. Behind and a few miles back (heading North) is Flagstaff, and about 15 miles South (looking relatively straight ahead) is Sedona.

The images in this row and the four rows below it were all taken in Oak Creek Canyon
in the area of a wide, dry creekbed, just off 89A.

The photographs above left and right were taken in the creekbed directly above-center.
That is what the bottom of the dry creekbed looked like throughout.

This ends the series of pictures from the creekbed. I'm guessing it may have once been a tributary of Oak Creek, since Oak Creek is running parallel to it and extremely close-by, barely more than a stone's throw away.

Sierpinski Tetrahedra complement the turning leaves of the Scarlett Sumac (Rhus glabra), taken along 89A.

A Level Two Sierpinski Tetrahedron is stacked inside a Level Three in these two pictures taken along 89A. The bush, called Lemonade Berry (Rhus trilobata), is growing straight out of the rock wall, many feet above the ground.

The above two pictures were taken at a little trout fishing stop directly off of 89A.

These images were taken on a different trail that had fee parking. Oak Creek is visible in the background of the picture on the left. The sunlight is almost shining through the tetrahedron in the second picture. I believe this effect is caused by enameling the heavy cardstock they are made from, which gives the paper a transparent quality. The purpose of enameling the paper is to waterproof it. It also adds strength and resilience to the cardstock for an overall stronger structure.

A good number of bushes were growing right out of the high rock walls here.

This is still the same area, same trail. Down the trail just a few feet, a tributary of Oak Creek has to be crossed on a log, if one is to follow the trail. The log is stable, it doesn't float or roll, but it is round, wet, muddy, and slippery in places. I had to cross the tributary on the log while carrying the tetrahedrons.
