ficent geysers ceased dormancy and entered very active periods within a few months of each
other.
Comet Geyser's cone is to the west of Daisy and closer to the northern walkway. Deposi-
tion of minerals from water droplets splashing almost constantly has built the cone.
E XTENSION TO B LACK S AND P OOL
If you continue west where the two walkways around Daisy become one, you'll see the White
Pyramid (or White Throne), the cone of an extinct geyser, across the meadow to the north.
At its base is small but active Pyramid Geyser.
A little farther west is the almost perfectly circular Punch Bowl Spring*. The center of this
beautiful spring boils a foot or so above its rim, which is nearly 2 feet (0.6 m) in height. It
overflows constantly, creating a colorful runoff channel.
Geyserite precipitating from Punch Bowl Spring has created a finely sculpted bowl.
It's a short distance to Black Sand Pool *, the last major feature on this route. Black Sand
acts infrequently as a geyser and has a large and colorful runoff stream to its west. The area
at the base of the runoff was named Specimen Lake (when it had more water) for the “speci-
mens” of still-standing silicified trees killed by Black Sand's runoff. In and around Black Sand
Pool you'll see good examples of the black volcanic sand that gives the pool and the geyser
basin to its southwest their names.
The small but deep, dangerous crater just across the path and south of Black Sand Pool is
called Demon's Cave. Avoid going near its overhanging ledge.
You can continue from here to Black Sand Basin (described on pages 70-72 ) or turn back
to the Daisy Group.
If you return via the northern path past Daisy, you'll meet the bicycle path toward Bis-
cuit Basin. Biscuit Basin is 1.3 miles (2.1 km) from here (described on pages 68-70 ). This path
