Artemisia Geyser (at left) is off the beaten path
from the Morning Glory area, and as such is
fairly undisturbed. I have not seen this geyser in
eruption, though it is one of the most appealing
features in the park.
Below is another need for correction. As
these hot springs are unmarked on the trail, I
have yet to get confirmation on whether this is
Gem Pool or Mirror Pool. I think it's Gem Pool.
It's down the trail a little from Artemisia Geyser.
As this path gets few hikers, this feature also has
remained pristine.

From the Upper Geyser Basin is
Biscuit Basin, connected by the
Artemisia Geyser trail. The name
"Biscuit Basin" was named after
biscuit-like formations around Sapphire
Pool. After the 1959 earthquake,
Sapphire erupted and destroyed the
biscuits. Just a little place-name trivia
for you.
As it turns out, my photos from this
basin have been misplaced (I hope the
other computer didn't eat them). Once
I recover them I'll post them in a hurry.
Also adjacent to the Upper Geyser
Basin is the Black Sand Basin... for
some reason one of my favorites.

At right is Cliff geyser, a small but frequent player
along Iron Spring Creek.
Below is Emerald Pool, well known in the Black
Sand Basin, mostly for its deep green color.
Below right is a photo of Sunset Lake. It's
actually a geyser, and like Grotto, I've only seen it
erupt once. However, it should be noted that its
eruptions are very cool, and it is by far one of my
favorite geysers (though Echinus Geyser is
probably my very favorite).
Sunset Lake is also located in the Black Sand
Basin, and is worth a look if you're in the area.

Midway Geyser Basin is slightly north of the Old
Faithful area, and is home to two spectacular giants.
Excelsior Geyser is one of these two giants, and
though it tore apart its vent, it is still an awesome
feature, and is the largest geyser crater in the park.
This is the same photo of Excelsior found on page 1,
below left.
The other giant inhabitant of Midway is the park's
largest hot spring. It's so big that a photo of it from the
boardwalk does not do it justice. As such, the photo
of it (below this text) is not one of my own, but rather
one that I have borrowed from the NPS (yes, I'm
allowed to do that).
This is Grand Prismatic Spring, and you've
probably seen this before on book covers, post cards,
or photos taken by satellite. As the majority of us are
unable to get a birds-eye-view of this spring, we often
don't consider just how awesome this thing is. Look at
it for a moment. See how big it is compared the
boardwalk beside it?
