*Players can dig down to the rock layer by [[digging]] away all of the [[dirt]] (from each corner) which rests on top of it. On [[Freedom]] Isles, the soil depth varies wildly and may reach as much as 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 also avoids time being wasted in unsuitable mine locations. Depending on location, the rock layer may or may not be below the water level.
* The following types of [[Resource nodes]] can spawn on Rock tiles do not amass collectable snow during the Wurm winter: [[Mineral debris]], [[Rubble]], [[Snow pile]] and [[Lichen]].
