This is not the best area in Unaweep, but there's potential for some some good face and slab climbs.
From Whitewater, head toward Gateway. The Reba Boulders are located between Texas Block Area and the Rock Garden. If you head past Texas Block about 0.5-1 miles, there's an unpaved pull-off (there's a paved pull-off about 100 yards after if you miss it). From there, head back north about 0.1-0.2 miles (5 minutes)and head east. It might take some looking, but it was a pretty good time.
