You can not raise a rock tile, but you can raise the corner by dropping [[Pile of dirt|dirt]] or [[heap of sand|sand]] on it.
One can dig to the Rock layer by [[digging]] up [[dirt]]. On the [[Freedom]] Isles many players and community assistants consider the average soil depth to be between 150 and 250 'dirts' deep in the majority of locales, however this figure is [[Talk:Rock_tile#Soil_Depth|widely contested]]. Depending on location this the rock layer may or may not be below the water level.
