The "sub tower" is a classic deep Catalina dive with an interesting "back story."
Some people don't really like it but I really enjoyed it. It is a great scooter dive and allows you to deco up the wall if you want. We had 53F at depth 57F on the last deco stop. Runtime was 72 minutes. Visibility was 40-ish feet with a slight current.

Here are a photo of the flange where the submersible would dock:
