The Barrel Cactus is also known as "Compass Barrel Cactus" as these cactus generally leans southward, towards the sun. 

The Barrel Cactus can turn dangerous when not handled properly. The puncture to human skin from one of the spines is considered a "dirty wound." I have published an article about Barrel Cactus in my 1979S blog.
