Ace of Spades 

This excellent route with clean rock, good position and memorable moves is a treat for those who like quality crack climbing, and is one of the recommended routes at the White Cliffs Of Dover area. Four stars out of five.

The bolts at the anchor are 3/8"

I remember this as one of the best 5.9 routes in the park, and just as good as Touch N Go or Pope's Crack. Do it!

A fine route, well protected, but no more than 5.8.

This climb is plently of fun, even if you already did Popular Mechanics. The climb is 5.9, the guy who said it is no more than 5.8 must have had a low gravity day.

Beta:
The anchor is about 10 vertical feet above the Popular Mechanics anchor and it is a little to the left of the end of the crack. You cannot see it from the base of the climb, but it is there. Rap is about 90 feet.

I'm surprised at the low ratings, especially compared to Popular Mechanics. I think this is the better of the two, as you get to do the meat of P.M., and then veer off the dihedral into a splitter crack for some varied climbing on great rock. Fantastic route, I'm tempted to give it 4 stars, if it was a 5-star system I certainly would.

5.8? Meh, could be. Not the toughest .9 in the park, but it's fairly sustained and has a few moves. It's close enough, not worth worrying about. I have absolutely no idea how you would assign a PG-13 rating to this climb.

Beautiful line! Three cracks go up the steep face starting at about the midpoint of popular mechanics. The center crack is the money. I made this harder than it had to be by using only the center crack (5.9+ IMO if you do this, which I highly recommend) since I showed up dead set on pure jam climbing. If you use the right crack as well, which gives you a positive rail whenever you need it, it's 5.9- at most with pro aplenty. In any case, the fact that you climb the best section of Popular Mechanics and then get 50 plus feet of this gorgeous line on the highest quality stone in the park makes this arguably the best 90 feet of 5.9 climbing in Josh. Add the several hundred vertical foot hike to the base and you feel like you're 400 feet off the deck while you're cruising the crux. SSSSWEET!

This route never gets old. So classic. Climb the first part of Popular Mechanics and when the crux breaks, head left up the double crack system to a great anchor.

One Beaut of a route!!! Crux down low, but protects well with small stuff. Climb the double cracks with some amazing quality rock! The anchors are up high and left, slightly strange, but they are there and that's all that matters at the Tree.

A Must do at the White Cliffs Of Dover!!! AMazing!!

As fine a pitch as you'll find anywhere. Reminded me of Bishop's Terrace at Yosemite - similar style and difficulty. This route is only 5.9 because of the thin corner move on the lower section that is shared with Popular Mechanics. The upper crack felt like 5.8.

Great climb. Loads of fun on good stone. Lol it does kinda climb like Bishops Terrace in a couple moves or so. good call
