Dotted Hole is not a normal cave once you fall down the first hole you must fall down the holes in a certain order and the order is: Up, Left, Right, Down.
You will need to fall through the ice (walk on it a second time and it will collapse) and work your way around until you get to the HM for Waterfall, teach a Pokemon that and you can then proceed with the hunt for the Sapphire.

You can get HM Waterfall in Ice Cave (Four Island). You'll need Surf and Strength to get to it. Push various boulders around and fall through a few holes and soon you will find the HM on a ledge.
