The last cactus photo was a very young Teddy Bear Cholla and here is one less than 2 feet tall with many branches. This is not full grown, although the ground perspective gives it an illusion of a larger size. The soft focus, yet somewhat eerie looking background complements and contrasts the cactus. And with those spines will be well protected in this environment.
As you can see there are a couple of branches that have fallen from the trunk and not laying on the ground. Possibly the branches have become attached to a passerby and transported elsewhere, to grow a new specimen.
