Obsidian is found in mountain caves and volcanic areas in ARK: Survival Ascended. It's used for crafting Polymer and camera equipment.
Node yields assume the base harvest HP from game data (e.g. 1000 for Redwood trees, 620 for Metal nodes). In-game, trees and rocks with bAllowHarvestHealthScaling have per-instance HP that varies with the node's size, so actual yields per node will vary. The values shown represent the average.
