The Artistry of the Slot Canyon


I like the glimmer of sunlight coming down through the top of the slot canyon highlighting the desert varnish near the top of the canyon wall.

Desert varnish results from a dark coating found on exposed rock in dry areas.

The dark coating is composed of clay, particles of iron and manganese oxides along with trace amounts of organic matter. It is usually brown to black in color.

The clay reacts chemically when the rock reaches high temperatures in the desert.

Sometimes petroglyphs are carved from scraping away the dark desert varnish layer to expose the lighter color of the rock below.

This photo has an interesting contrast with the yellowish ray of light on the pattern of the desert varnish and the texture and color of the sandstone wall below.

It makes me think of a pile of satin ribbons!

I found the light in the slots magical and the mineral stains part of natures painting on the sculpture of sandstone.

I feel as if I'm being enveloped in a Georgia O'Keefe painting when I look at these. This was an amazing photographic expedition, Julie.
