There are more-qualified individuals on this board to answer these questions, but I'll throw this out. Beacon Rock is known for its multi-pitch trad basalt crack climbing. The rock quality on the popular lines is very good. Popular lines have bolts at the end of each pitch, but usually no chains so webbing is frequently left behind. A good introduction would be the SE corner route which is considerably easier than most others at 5.6-7. I find grades below 5.10 to be pretty stiff for the number, but a 5.10 feels like a 5.10 at other places (figure that out). If you can climb 5.11 crack you will be well-served here. One hazard to note is to be aware of rockfall off the top when you are along the wall facing the river. Tourists can knock stuff down, and climbers pulling ropes after rappels can bring down a lot of loose stuff too. The standard guidebook for the area is "Portland Rock" by Tim Olson. Hope that helps.
