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 the soil depth varies wildly and may reach as much as 250 300 dirts to the rock layer, though this is very rare. The average depth is however [[Talk:Rock_tile#Soil_Depth|widely contested]], and the factors such as slope, elevation and random chance strongly affect the depth at which the rock layer is found. It is advisable to dig a deep pit to discover the rock layer before attempting to create sufficient space to create a mine, as this aids planning and avoid time being wasted in unsuitable mine locations. Depending on location the rock layer may or may not be below the water level.
