So according to several news sources, the first full moon is called a "wolf moon".  This name comes from native American lore where each full moon of the year has a name.  The "wolf moon" is named such due to the sounds of winter wolves howling under a full moon (source) .  So with clear skies, like any intrepid photographer, I headed up into the geyser basin after dark to photograph the landscape under the light of the "wolf moon".

Above is Old Faithful Geyser in full eruption lit by the full moon.  The image was roughly 6 seconds at f5.6 at ISO 1600.  Notice the lack of snow on the ground here.  While this is a thermal area, in a typical snow year, the ground here will not be bare.  Even with recent snow falls, the warmer ground in the geyser basins show a lot of bare ground.

This image above is of Grand Geyser.  As I made my way past Castle Geyser, I heard the sound of Grand before I ever saw it.  A three burst eruption gave me time to get over and record the eruption under the full moon.  In this image, Grand is the back and most of what can be seen is just steam.  The jetting water in the front is Vent Geyser.  This image was shot at 4 seconds with an f-stop of 4.5.  I also used ISO 1600 here.  There was a lot of steam, giving the image the look it has here.

Finally, this is Castle Geyser in the back and center of this image.  Again, the full moon provides backlighting through the three steam plumes.  This image was also shot at an exposure of 4 seconds, 4.5 f-stop, and ISO 1600.  Focusing for all the images I took under the full moon was done manually.  No adjustments were made to any of these images on the computer except some noise reduction.
