As the number of ribs seems to go down at the narrow bits I assume that this plant did not enter dormancy in winter, and therefore as the amount of light reduced it etiolate slightly. Possibly because of some genetic defect?
People's thoughts?

My guess: rot has invaded the central core, and the external flesh is dehydrating from lack of moisture and nutrients. A high percentage of large transplanted saguaros end up looking like this before they collapse. RIP

Agreed -- all of those bulges on the stem indicate a rot-induced collapse of the core.Tom in Tucson wrote: ↑Mon Jan 16, 2023 7:43 pm My guess: rot has invaded the central core, and the external flesh is dehydrating from lack of moisture and nutrients.

Re: Strange Saguaro
If you look closely its actually growing and losing ribs...
I can understand that it looks like its collapsing on its self but I think it is just gaining and losing ribs.

The growing and losing ribs thing is what made me think it was something other than core rot.LateBloomer wrote: ↑Mon Jan 16, 2023 9:28 pm If you look closely its actually growing and losing ribs...

Good evening dear cactus friends,
I think it is a growth disorder.
It has been going on for a very long time.
On the picture you can see some spots which suggest this conclusion.
...
I had photographed a similar plant a few years ago.
