Title: Skeleton of a Cactus
Post by: pluton on November 15, 2016, 05:32:35
Sometimes you find these as you walk along in the desert.  From the spines, it appears to be what's left of a barrel cactus.  D3 with a 28mm.

You got rain & clouds finally? Show us the lush green hills you were talking about!

Love the intense color of wet stone with lichen

This is a true objet trouvé.  I've never seen or thought about such a remnant of a cactus.  Well depicted.  Thanks for sharing!

Fascinating structure of the cactus, enhanced by the stones and lichens

An exoskeleton in this case, unlike the endoskeleton of the Chollas. Well seen and captured.

Very interesting! And nice photo with the touches of lichen colour in the background.
I love the desert plants and animals.

Just a shady spot in a typically dry area, Kofa National Wildlife Refuge, Arizona.  Absence of dust on the smooth rock may give an impression or illusion of wetness.   The next night it rained and then snowed(lightly)!

The surface of the rock is covered with desert varnish http://www.abdnha.org/TSP-desert-varnish.html (http://www.abdnha.org/TSP-desert-varnish.html), a coating of Fe and Mn oxides which can often present a shiny surface.

I love this photo!  It brings back memories of the deserts where I spend time many years ago.
