⚠️Requires Terralith and Vanilla Backport
The yellowstone biome lacks its most iconic feature: geysers.
This datapack adds a chance for potent sulfur blocks to generate above magma blocks in the biome, creating natural geysers. Sulfur vents generate underwater in shallow areas.
This datapack is a backport of the same feature that was added to Terralith in version 26.2
