Organ Pipe Cactus National Monument



Organ Pipe Cactus National Monument is a national monument and a UNESCO biosphere reserve in the Western region of Arizona, bordering Mexico.

Understand
More untouched and lush (for a desert that is) than more easily accessed American southwest desert parks, Organ Pipe Cactus National Monument was created to protect its namesake, the organ pipe cactus, the monument being the largest concentration of the plant in the United States. It is in the extreme southern portion of Arizona and borders along Sonora, Mexico. The visitor's center is less than 10 miles (16 km) from the Mexican border. The nearest large population centers are Tucson and Yuma, both over 150 miles (240 km) from the monument, though several small towns with gas stations, hotels, and groceries are near the NORTHERN borders of the park, and other towns near the southern edge, if you want to drive across the Mexican border (the single US highway into the park continues directly into Mexico).

The monument is a through-route between Arizona and Puerto Peñasco (also known as Rocky Point) in Sonora, Mexico. Just 5 miles (8 km) south of the visitor center is the US Port of Entry in the town of Lukeville and the Mexican Border Customs in Sonoyta (Aduana Fronteriza de Sonoyta).

Flora and fauna
Though named for the Organ Pipe Cactus - the park has far more saguaro cactus than those of the organ pipe variety - in far higher concentrations than say - Saguaro Cactus National Park, also of Arizona. In essence, the park is a relatively lush and untouched American southwest desert environment, with a far higher concentration of cacti and other desert plants than perhaps anywhere else in the American southwest - with a decent and best in US, but not exactly overwhelming (this is the northern end of its range), number of organ pipe cacti interspersed.

Climate
Summer months are hot, with temperatures exceeding 100F. Winter months are milder, with temperatures in the 70s, with overnight lows in the 40s.

Camping




Backcountry
Due to border security concerns, the backcountry is closed indefinitely.

Deserts
The monument is a remote, desert wilderness. Be sure to carry plenty of water both in your car and while hiking and drink regularly, even if not thirsty. If your car breaks down, stay with your car rather than attempting to find help on foot. It is much easier to find a vehicle in the desert than a person.

Arizona / Mexico border
As mentioned above, the monument is on the U.S.-Mexico border. Due to the remoteness of the monument, it is used for illegal border crossings. Most of the persons illegally crossing present no threat to park visitors. However, there are some who use the monument for smuggling who are armed and dangerous. In 2002, a park ranger was shot and killed by a drug smuggler. The Kris Eggle Visitor Center has been named in his honor.

Visitors should be aware of their surroundings and report suspicious activities to park rangers or border patrol officers.
