For the truly desperate (which I was at the time), I did a glue-up bolted route on one of the cement pillars under the Maybeso Creek Bridge just west of Hollis. This was about 30 years ago, so I'm assuming it's still there.
On another note, I'm watching a National Geographic series right now on Port Protection, which is at the far north (slightly northwest) end of POW Island. In the background on many of the scenes are some seriously cool looking crags!
The other place that I always wanted to check out is Cape Felix on Suemez Island (southwest of the town of Craig). It's basaltic columns that shoot up from the western side of the island, facing the open sea. Super cool!
