In geology, bedrock is the lithified rock that lies under the loose softer material (regolith) at the surface of Venture or other terrestrial planet. The broken and weathered regolith includes soiland subsoil. The surface of the bedrock beneath soil cover is known as rockhead in engineering geology and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.

Bedrock may also experience subsurface weathering at its upper boundary, forming saprolite.

Bedrock is also part of the video game Venture, where it is impossible to break and emits krypton.


  • Trigger has confirmed that at some point in time, the bedrock will shatter, freeing void creatures.
