Midway Geyser Basin

Yellowstone NP SM19-237

In the west central portion of Yellowstone lurks the geyser basin, which has the greatest concentration of thermal features, particularly geysers, in the park, including Old Faithful and the Grand Prismatic Spring

I spent a morning and part of the afternoon exploring the Midway Geyser Basin, the most prominent feature of which is that aforementioned Grand Prismatic Spring. The Spring resides right next to another impressive thermal aperture, the Excelsior Geyser which, when I was there, mostly just lets off enormous amounts of hot air, which creates a white trail against the clear morning sky. Here are some images taken from the boardwalks that lead to the Grand Prismatic Spring. Note the paucity of Grand Prismatic Spring photos taken from the boardwalk. That's for two reasons: (1) it's difficult shoot the spring from the boardwalk because it just doesn't look as impressive close-up; and (2) in the morning steam is rising from the spring and blocking the view.

First, some images of the surrounding area:

To get a photo that really shows off the Grand Prismatic Spring, you have to hike up a hill that provides an overlook. You also must wait until the middle day when the spring stops producing so much steam. By then parking has become a very serious problem in the Midway Geyser Basin. Even on the Wednesday after Labor Day, I was lucky to grab a spot at the parking lot for the trailhead. Here's a couple of images from the overlook:

On the way back from the overlook, I ran into this guy, who was all by himself looking for something to eat in the barren, volcanic landscape:
