🔥 Yellowstone Geyser Wakes Up After 6 Years of Silence 🔥 A rare acidic geyser in Yellowstone’s hottest basin has suddenly come back to life. Echinus Geyser jumped from total quiet to eruptions every few hours, sending up blasts of hot water and dropping the pool to the bottom each time. Sensors are catching sharp temperature spikes as the system surges and drains, showing rapid underground change inside the most unstable ground in the park. #Yellowstone #GeyserWatch #NorrisGeyserBasin | Above
