I found an area in 1.8 where I could mine some of the new stone. After walking around a little I noticed there was a nearby ocean. 8 night vision potions and 10 boats (these things still break way too easy) later I found an ocean monument!
I chugged an underwater potion and took a quick look around. These things hurt and really hate squid. Time to set up camp on a nearby island and going on a raiding spree later tonight.
