The main area is getting pretty well developed with lots of room for more routes. Remember, we don't have to grid-bolt everything. Top roping is perfectly fun.
"Uncharted Territory" on the left looks like it has good potential for some 1-2 pitch routes. Including "The Fin" a lone pyramid of conglomerate on the side of a steep hill. Someone put a cinder block on top of it. This area might be more efficiently approached from the road below.
The "Nice Boulders" area has some good small route/highball possiblities but the brush is pretty thick so some limited gardening work might be required to exploit routes.
"Hoodoo Canyon" does not seem to have any decent lines that I could see.
