The first pitch ...

Adam topping out. He always makes it look so easy. Sorry about that rope potential. It's easy terrain but still :P

Brad White mid-route.

Allosaur from across the creek. Scramble in from the left and climb a 4th-class slot to access the route. The belay at the end of the first pitch is on a sloping ramp; other options are to belay at the rappel tree on the left, or run the first two pitches together. Two rappels to get off; a 60m rope is useful for the second rappel.

The second is approaching the crux of P2. The P3 crux is at the left end of the slanting overhang above the top climber. Thee somewhat runout 5.7 slab of P1 angles slightly left from the tree at the bottom of the photo. Another climber is just right of the tree.

Allosaur - the approximate line.

Good fun on Allosaur, photo: Bob Horan.

Brad White nearly through the crux, Great Route!

Approaching the roof on pitch 2 (done as a 3 pitch climb). The crux on pitch 3 climbs out to the V notch at the far left of the skyline.

Adam on pitch 2. Great!

Sorry for the blurr. Adam founding the corner crux of pitch 2.

An unknown climber in the middle of the 5.7 "slab" first pitch of Allosaur. I say slab in quotes, because the first half of this is quite steep. The route continues to the slanting overhang above, left around that (8 or 9) into the left facing, right leaning corner. Most people belay here, combining pitches 1 and 2. Out left below the final overhang with the crux being the last move pulling around onto a low angle slab.
