I have done some guided hikes up to finger rock, and every time I am on the trail I pass by what looks like some awesome climbing. If you are familiar with the trail, the area I am talking about is three miles in from the trail head on the West (left) side of the canyon. More specifically it is about 3/4 to a mile from where the trail transitions from relatively flat terrain to pretty steep. Looks to be about 90-150 ft, filled with all sorts of cracks and features. The rock is a pretty obvious reddish color, and looks like people should be climbing on it. Aside from a hellacious approach, it looks like some amazing rock.

Was wondering if anyone knows about route development at this area. Next time I'm up there, I'll take a picture and post it in case my vague description isn't clear.

I think that's Sedona.

If it's the place I'm thinkin...it's got a couple of route and they are loose and scary. Check Kerry's guide.

I believe you mean Thunderbird wall: http://www.climbaz.com/Backcountry/page_html/page118.html

Tho it's much taller than you suggested. 350', according to Kerry. Still, the guide says it's some pretty chossy rock. And, as you mention, one hell of walk.

If you think it is Thunderbird Wall, "Quest for Existence" is only one of MANY routes on it, mostly with aid sections.

could also be the thumb. its a few pages later in the bob kerry book. looks pretty good.

There are a few routes on trail right as you head up the canyon just before you reach the climbers trail that goes to Finger Rock.
