I spent 2.5 days at Peacock this past weekend with two of my dive buddies, and we got in 5 cave dives. 2 Saturday, 2 Sunday, and 1 on Monday before heading home. I took a bunch of photos -- here are a few in the cavern zone. My dive buddies also put together a few videos; I'll see if I can link that somehow.
Peacock 1 was completely covered in duckweed.
Enjoy the photos!
