I believe your cactus plant is a species of Pachycereus.

There are several possibilities for the drying of the tissues, or "corking". It could be a bacterial or fungal infection, worst case is "bacterial necrosis" which is common in the big saguaros.


But it could also be due to sunburn or phyto-toxicity. Has it been sprayed with anything? Intentionally or accidentally?
