Castle Geyser

After I left the ranger talk at Old Faithful, I saw Grand Geyser erupting in the distance.

When I got to Castle Geyser it was doing small eruptions, as was sawmill. At that point I thought maybe what I saw was sawmill. A bunch of us waited for Grand to erupt, but I found out much later it had already erupted.

I did a longer Ranger tout starting at Castle Geyser. Even the ranger was impressed to see it from the start of its cycle.
