I can see you are taking on quite a challenge yourself with his cache, Tat!

Maiden Cliff ....

There is a great perspective of this from Gravity Outlaw (GC9488) by quietbert (1.5/1.5). It's another one of those "It's a great spot to study it, but you're not really there" places.

IIRC, there are trails to the top, and you can drive right to the base, so a cache could be placed at the cliffs, but the cache mentioned could qualify depending on how liberal you wanted to be.
