Good flow on this one. Big moves, nice heel hook, jug start hold, jug finish, good landing. What's not to like?Stand start with a blocky left hand jug. This is the same start as Reptilian. Using jug foot, do a big first move out right to a small cramp. Then go straight up and finish on the side pull jug. Easy top out.  Walk off the back side.  Taller folks might ride the left heel the whole way. Shorter folks might use a slopey foot edge out right.  Dealer's choice. Tall person beta: youtu.be/I-bC51-lk8kLow start goes at V8-9. Start with right hand on the jug foot used for the standard start. Left hand is on a sloper pinch feature. FA: Dave Rosen

Reptilian is characterized by a slot pocket start with slap and compression moves heading out of the roof. It culminates in a great press to mantle to top out the boulder. It's one of the most striking lines on the boulder, and possesses truly pleasant holds in regards to south mountain bouldering.

From google map description: Unnamed Traverse V5 ** - Start just right of Tyrannosaur and traverse right to brick shaped ledges. Topping out early before the face is V2. Heartbreaker throw near the end, and topping out is a little heady. Going right may be better. 

One mover.  Start about mid-way through the un named v5 traverse.  About 2 ft below the last flat ledge you use before the V5 traverse turns into vertical climbing, you will find an obvious half pad, flat, glassy crimp. Start left hand here and right hand on either of the two micro edges down low.  Pull on with difficulty and jump to the flat rail.  Top out as per unnamed v5

From South Mountain Bouldering google map: One-move Wonder V2/3 - Start on decent holds and make one off-balance move to big hold. Topout (Far right of Photo 4)

Start left hand on poor crimp around arete, right hand on crimp/pocket on face.  Might need a pad stack to reach.  Some creative climbing gets you to two full pad edges and an off balance, but easier top out.  3/4 pads and a spotter is recommended.  Tension based moves with heavy swing out potential.

The T-Rex boulder is one of the largest boulders in the wash with a great landing spot for Reptilian(V9) and Tyrannosaurus(V8). Several other climbs exist on the backside ranging from V0-V3.
