The road to the Old Faithful geyser was closed because of the snow, so we went the other way and found some mud pots and steam vents.
It smelled very sulfury
This was the most violent one - there was a deep rumbling coming from it and it poured
some were watery, some were muddy, all with bubbles bubbling up
This was near the West Thumb area, called the Abyss pool - it is a beautiful blue and filled
with very clear water.
Then we found that the road opened up, so we drove over to the Old Faithful geyser to catch the scheduled eruption at 5:45pm
It was lightly snowing and very cold. There were a few teasing eruptions before
the final one happened about 5:50pm
the drive out of the park, very cold, snowy roads
