    100 Foot Rock, just as the name suggests, offers a deep dive along a substantial rock wall. You’ll find typical Pacific Northwest residents here: plenty of anemones, the occasional crab, and rockfish tucked into crevices. It's a solid choice for experienced divers comfortable with colder water and longer bottom times looking for a straightforward wall dive. Visibility can swing dramatically, so checking conditions is always a good idea.
