A Crested Saguaro Cactus is extremely rare. This will happen only once in about every 10,000 cactus. I talked to many people in the area and rangers to get some idea of where one might be in the hundreds of square miles of saguaros. A suggested area and many hours later, here it is in all its glory.
Saguaro desert near Tucson, AZ.
Canon 20D. 80>200 lens, polarizer and patience. I need to mention the binoculars to help cover many miles at a time.
