We left at 1835 had a wonderful day in the Grotto area. Nearly walked up on GF, which had quite decent height considering the short lead time it had on Grotto. I never realized Spa had quite this eruptive potential, 😁 |

Another awesome full pool eruption. Many bursts to the top of the trees including one multi burst where nearly every burst was to the top of the trees. Hopefully these strong full pool eruptions continue. |
