We had visited Old Faithful on a previous trip to Yellowstone and had stayed near the falls.  Therefore, I was not so desperate to see the geyser again.  However, in the middle of winter, things are a lot quieter than during peak season so it was quite interesting to be there with so few people around.  The geyser erupted not long after we arrived.  It was quite a different experience.  The low air temperatures meant that the hot water produced a lot of steam as soon as it emerged.  The clouds of steam drifted downwind but they concealed the flow of water to some extent.  Still, it was an impressive sight to witness and even better on a crystal clear day.
