Stand start between Henry the Navigator and Thinister below the layback features and in-set portion of the face. Follow technical moves along the lower wall into the better holds higher on the face. The top lip has confident holds and a nice top out.

Stand start right of The Treat below the notable crack/seam mid face. Stand start below the seam and work into that feature, topping out directly above over the good lip.

 Shout out to Prince Henry the Navigator and also Henry Dalby who climbed this rig first.

This is an awesome powerhouse compression. If only it were a few more moves!

 On the riverside face of the boulder, this one is on the left corner. The large block at the edge of the face is where you will find the line. Stand start down in the gap between the block and boulder, matched on the flat rail on the middle of the blunt arete.

 Toss right to the wonderful, large sloper loaf, and then to the left of the arete to the thinner sloper to compress. Bump huge to the good side-pull rail and then take it to the confident lip.

 This line is unclimbable when the river is high.

A fun little climb on its own, this one is good to get familiar with as its also the downclimb.

 Stand start wherever and use any holds and the arete to get to the top out. Then turn around and downclimb it.

Superb climbing on stunning riverside rock. Only climbable in low water conditions.

 On the riverside face, this climb is up the far right side close to the corner.

 Look for the large, rounded left facing jug rail. Start matched on the jug rail and either move right to use the thin high right edge to compress, or dyno to the higher left edge. Continue to the large jug and then a series of thin edges to gain the lip. Work through iron features above to top out.

Tall, beautiful rock and classy moves. To the right of the front steep overhang. Walk around the corner to the vertical face near the river. Close to the overhung arete, look to the right about 4 ft to find low compression holds to start with nice feet.

 Climb up past nice holds to a perfect pinch mid-face. Make tricky move higher up to the jug ledge and confident top lip to top out.

Stand start low 4ft left of the "Downclimb Arete" using a low, flat diagonal rail and a flat undercling rail left of that.

 Establish and work directly up the slab past balancy feet and edges to top out.

Pretty great!  Once under the overhang, locate the massive jug toward the left of the steep terrain. Start here and trend slightly left into the giant plate flake. Work up the crack of the flake and once at the top of the flake climb directly up the high face past good holds, tiny crimps, and a neat-o slopey hold.

Hard slab/vert on great stone with a nice landing. To the far right of the face (right of Marsh's Bday) look for two very thin, rounded incut crimps. Establish and fire up to another edge, then another to then work left to a good rail. Follow better holds up to the nice top out. 

Identify the high left-facing layback flake features. Stand start beneath them on the low jug. Climb directly up to the laybacks and continue to the high top out.

So good!

 On the riverside face this one climbs up the middle. Look for the large diagonal sloper ledge in the middle of the boulder, and then the long diagonal crimp rail below it.

 Start low matched on the rail, toss to the sloper, and then work through a pocket and a series of flat holds and excellent scoops higher up. Top out and find the hidden but important deep pocket for the top out.

 This one is unclimbable when the river is high. Build a water landing even when water is very low.

This massive boulder resides nearby the stunning Casablanca Boulder. Pentagon is tall, highly featured in some spots, and blank in others. There is steep climbing, vertical terrain and some slab.
