That thing is huge for sure. The setting is also super nice.
I am sure you have checked out Nick Dodge's book. It has route desriptions for the pillar, and the other rock in the valley.

There is also a old school picture posted in the gallery of the pillar, PM poster.
From what I remember out of Dodge, the route is mixed with pins and gear, most of which is shit.
That all I know, good luck
