Video @ladzinski / Yellowstone’s #grottoGeyser erupting under a veil of stars in the early hours of the night. This geyser generally erupts every 8 hours, but times can vary slightly. Seeing it erupt at night makes you feel like your on another planet. My camera was completely drenched in the making of this clip but totally worth it! #YellowstonePledge @yellowstonenps
