Like junkman said putting the pole on a rock 6 inches down would be fine in florida because once the whole structure is done sideways stability is inherent to the structure. Biggest problem as mentioned is frost heaving. If the base of the rock extends below the frost line you're ok, if not the rock has the potential to heave as will the pole sitting on it. Problem is there's no way of knowing what the shape/depth of the rock looks like without digging it out /forums/images/graemlins/frown.gif. Last thing you want to do is put up a building only to have a corner push up in february!! /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif
