Bottom Characteristics
A steep beach slope, such as the one pictured above, indicates a steep bottom contour.
Bottom Contours
The contours of a site have a dramatic effect on the site's depth range and diversity of life. Like bottom composition, you can usually predict the contours of a site by observing the slope of the nearby coast.
Most divers prefer sites that feature steep or vertical bottoms because they host a wide variety of life. Flat sites may also be rich with life, but you're not likely to see much diversity from one location to the other.
When diving steep sites, it's important to watch your depth carefully to avoid descending below your maximum planned depth. The best dive plan in these environments is to begin your dive at your deepest planned depth, and work your way up to shallower water during the dive.
