This is a bunch of reef fingers slowly running into the deep (max depth 60 ft or 18m) so your profile takes you up and down (as you were taught not to) but at shallow enough depth that its a workable profile. Tons of places to hide for frog fish (listen out for them) but also some sandy areas. In short a dive where the time flies as it always does..

Here is a classic shot of what to expect..[roncasual]
