20612 09 Dec 2021 @ 1207 --- JarnoO (wc) At 1207, following Lion's 1205 minor eruption, both Lioness and Big Cub became very steamy to the point there were hints to a billowing steam plume. Big Cub's plume was narrow, continuing to just after the 1208 minor/roar of Lion (totalling ±2m); this activity ultimately resulted in a few splashes just before Lion had its minor/roar.
