White Star Quarry, so here are a couple from late last year with my SeaLife camera.
Anyway, the above pictures were taken above and inside the crusher pit. The top of the pit is at about 45 feet and the bottom hits about 75 feet. The fun part is going up through the tunnel! Now, you have to have your Advanced Open Water certification and get permission from the quarry in order to go through. It is an overhead environment and you need the appropriate training and equipment. It's a little weird the first time, but after that, it's pretty cool. It's about 40 or so feet long, with a height of about 4 feet by probably 6-8 feet wide. Big enough to drive a small car through, and if the visibility is good, you can see the light at the end as it slants back up to the block house. So it's not too scary, but again, I emphasize that it's not for everyone, experience in an overhead environment and the necessary equipment is extremely important.
Hopefully, next weekend Jeff's back will be up for diving and I'll have some new pictures with the new camera housing!
