gave Culvert Geyser the energy to enlarge its crater and begin spouting to 2 feet (0.6 m),
which it continued to do for some years. It is now a clear or colored pool with prominent
overhanging edge.
(B) Between Grand Geyser and Sawmill Geyser, the straight walkway has only three small
springs. Bulger Spring (on the right as you walk toward Old Faithful Village) is actually a
small geyser. The seemingly unremarkable springs on the left are interesting because they are
not connected underground, according to geyser expert T. Scott Bryan, although their aper-
tures are only one foot (0.3 m) apart. Crystal Spring, named for its very clear water, is connec-
ted to the Grand Geyser Complex, but Crystal Spring's Geyser (a round hole right by Crystal
Spring's runoff channel) is a member of the Sawmill Geyser Complex.
(C) Back on Geyser Hill. When the boardwalk splits near North Goggles Geyser, turn left
to take the upper part of the loop and see the features you missed at the start of Geyser Route
One.
Ear Spring is obviously named for its shape and used to be called the “Devil's Ear.” Haynes
Guide in the 1920s reported that “it not only resembles an ear in shape, but the lobe is pierced
and the earring is a tiny geyser. It is here that messages are transmitted, so the story goes, to
regions below.” Sometimes Ear Spring's water becomes superheated (hotter than boiling), and
bubbling occurs around its rim.
The western end of the trail to Solitary Geyser and Observation Point joins the main
boardwalk between Ear Spring and nearby Beach Spring. In rainy summers, the meadow
north of here is filled with wildflowers.
Beach Spring in the boardwalk's corner may get its name from the beach-like terrace its
water intermittently flows over, the sandy color of the sinter in its central bowl, or perhaps the
sound it makes during boiling periods: like surf at a beach. If you watch for a few minutes,
you may be hypnotized by seeing the water rise, bubble, and fall repeatedly a short way down
in the bowl.
Aurum's bubbling and erupting causes geyser eggs (foreground) to form.
