When Prickly Pear cactus become severely dehydrated, they often take on colors like yellow, red and purple. I shot this one at the very end of our hike yesterday. I need to go back with my macro lens and work this!

Also…a repeat of yesterday’s photo. With no sun, it wasn’t a great exposure to begin with. I did a quick Photomatix HDR which I didn’t particularly care for it so I worked on a single image this time turning it B/W with a hint of color. Much better, I think.
