159814 Saguaro           Discovered 2003 Sept. 27 by KLENOT at Klet.
The Saguaro National Park located in a desert landscape to the east and west of Tucson protects the majestic giant saguaro (Carnegiea gigantea) as well as other cacti. The giant saguaro is the supreme symbol of the American Southwest.
