Organ Pipe Cactus National Monument

Just down the road from Ajo, is the wonderful Organ Pipe Cactus National Monument. (You do realize that this isn't a short 'down the road'?) This cactus species has several narrow stems that rise vertically, growing from a single short trunk just above the ground level. These stems are about 6 inches thick and grow to a height of 16 feet.It takes 150 years to reach maturity.

And some of the straightest roads I have ever seen! It looks like someone used a ruler to plan them!
