From left to right this would be route #3. This climb follows a cool rail feature that snakes up the slab. The first moves are the crux so a stick clip might be handy if 5.8 is a challenging grade for you. 

  Start out the lip of a small cave (crux) to the first bolt. Climb up and left on in-cut holds to the anchor. This used to share an anchor with Outer Bounds 5.8+ but now has a nice independent anchor to the right.

Newly cleaned and better traveled this climb is now a much more worthwhile endeavor. The spacing of the bolts is a bit less generous than most Rumney climbs though there is enough to keep you safe. I think this adds to the quality of the climb rather than detracting, Excitement factor :) 

  Interesting friction climbing and edging up to a slanting crack/flake, follow this right then Move back left to a pull over a small roof atop the boulder.

The left-most route at the crag.  A hard start, then angle up and right with your feet on ribs.  Once you reach the ledge above, step left onto a block and clip a hidden bolt for the top-out. 

  As of now, the only clean route on the crag.

The right-most bolt route at Boundary Rock.  Crank up and left out of the shallow cave, then foot traverse back right along the quartz patina rib to the arete. 

  A good start, but the finish is a hike.

Boundary rock is really a boulder not a cliff. There are two bolted routes on it, they check in at 5.8 and 5.8+. the climbing is slabby for the most part with a few steeper moves. They are fine routes but not really worth the hike unless you are like me and want to climb every route you can. If you are looking for a reason to check them out it might be the only place you can climb a couple 5.8's on a busy Saturday and be pretty damn sure you will have the place to your self. Might be a good warm up if you are on your way by to one of the other western crags up that trail.
