Organ Pipe
Stenocereus thurberi
Finally, not a cholla! (I love chollas. Sorry.) The organ pipe is one of the grand daddies of all the cacti—it even has its own National Monument!
The organ pipe is very distinctive: it has a handful of narrow stems that grow from a single base. The “pipes” are about 6″ in diameter and grow to about 16′ tall.
