This is a beautiful tiny lake in Santa Rosa called Blue Hole.

Its spring fed from the bottom so year round its the same temperature and this clear. The square shape you see in this picture is a diving platform. Skin divers dive down to this platform which I believe is 15 feet down. There is one below that which is 25 feet.

Andrew and his best friend Matt would spend every free minute swimming here. They would dive off the rocky edge and swim down to the first platform.

The photo below shows the rock shelf on side wall of the lake. Its so clear and so beautiful - you can look up videos about it on YouTube.

This is a photo of Andrew swimming up from the platform.

And here he is - standing on the rock shelf in photo three.
