Basalt

"Is stronger even than me!"

- Wolfgang Basalt is a blockade which can't be moved or destroyed. It is similar to the Tree Clump. It occurs frequently in later worlds of Adventure Mode.

Basalt was added as a placeholder for Sinkholes. Upon the release of the Underground update, all Basalt in Sandbox Worlds were to be replaced by a Plugged Sinkhole.

Trivia

 * When Maxwell examines it, he says: "I made a rock so heavy that I can't lift it." This is a reference to the Omnipotence Paradox.
