Eureka Oil Rig

Diving the California Oil Rigs, Part 1

(This is a continuation of my previous post on the California oil rigs.) The platforms are formidable structures both above and below the water. The water was green and murky at the rigs this weekend, with visibility in the 15-foot range. The vis did start to open up below about 100 feet (our maximum depths []
