The fixed main line starts just inside the mouth of the cavern, so I jettisoned my primary reel, and we swam up the Pothole line to Olsen Sink (1400 feet) in 29 minutes, spending 51.3 cu. ft. of EAN 32%. After enjoying the scenery of topside Olsen, reminiscing about the old days walking down the treacherous path in double 104's and slippery wet suit booties, we swam back the same way.
Conditions: A bit cold at 71 degrees F, especially on the return. Visibility was decent; estimated at 60 feet, with fine particulate matter in suspension noted in several areas, with negligible flow throughout the dive. The open water and cavern was clear and beautiful. We met only one other team en route. Very enjoyable, relaxing dive, with two fine friends. Nice to see conditions improving, although they are not quite back to normal yet.
