Faithfully

Old Faithful, being faithful.

Hotty

This hot spring looks like a giant sliced agate.  A deadly, deadly agate.

Patiently

Saw this couple on our way to the hot springs.

Drippy

Gibbon Falls flows over volcanic ash.

Deceptively

It looks like snow and ice, but it's really a hot spring with microorganisms that love the heat and gases and toxic stew.
