Great dive. Started as a 3 man team, but one buddy had catastrophic 1st stage blowout on his BM doubles about 100 ft. after jumping onto the gold-line (entered via Martz), and had to leave the dive. Equipped with a stage, he felt safe to go it alone to the main entrance, ~600 ft. away.

Guy & I continued to Rocky Horror, and turned at the elbow of the Courtyard, with a penetration of 4200 feet, max depth being 119 ft. We too exited the system via the Main spring. On 31%, I had a deco of 2 mins. at 20 ft., and then 8 at 10 ft.

Very nice starter cavern! First dive as cavern certified. Did the horseshoe 5 times. The rabbit hole gets wilted easily going in, but the flow pushes it away almost immediately. Had to crawl into the rabbit hole and the big opening.

I went scuba diving here on 7/26/2016. Average viz: 5-10ft/2-3m. Water temp: 71-75°F/22-24°C.
I was the 3rd diver in a 3 party team, therefore, my vis was quite limited as we explored the crossunder tunnel to approximately 1600 feet.

The passage is low and way silty, but the dive was quite enjoyable, nonetheless. Lood forward to doing it again in the near future.

Amazing cave, did the godzilla circuit, then swam up the mainline past the half hitch restriction. Great dive here.

Didn’t do cave; buddies were cavers so I hung out at entrance and enjoyed it. Clear.
