7/15/2023 | Matt Batson | N/A did not dive | Did not dive but the basin looks to be murky from the surface. Not too hard to access, but there are lots of broken bottles and trash along the trail. |
11/5/2005 | Mike Emanuel | 25' - 50' | Basin has started to invert and visibility is increasing. Cavern is gin clear after you wiggle past the jumble of lines and junk and drop down along the back wall. Agree with previous post regarding the current state of the lines. You'll have to run your own to get into the deeper section. Looks like things have shifted over the years and all the lines seem to be pinched off. The breakdown in Lost 40 doesn't really support line wrapping, so I'll bring some supplies and try to forge a new permanent line the next time I dive it. |
10/26/2005 | Jay Titen | 10ft max | Visibility in the basin was 5-10ft max. Entrance to cave was extremely silty and line in cave was in terrible shape and should NOT be trusted. Run your own line and be careful for line traps. This place is worth the dive once, but is all in all a nasty silty hole in the ground. |
