Yep, this is Rimrock Spire. Right off the east side of I-70. And yes Harvey did 2 routes on it and Fred Knapp, Sharpend guru, did them both free at 5.10d. BingBong is on the right side and Northwest is on the left side. Actually pretty good climbs if you can put up with the highway noise.
Beware!! When you're finishing the second pitch, the huge boulder that you stand on (that is teetering half off of the ledge it is sitting on) is ready to come off! And if it does, your partner/belayer is screwed!!!!! I was solo. It is so loose that I was moving it around with very little effort! I think it was loose the last time (Jan. 2008) I did this tower, but I forgot about it or I wouldn't have went back. Other than that, it's a good route. The summit pitch is easy, one .7 move with good pro. Go all the way to the west end of the ledge.
