The image shows a closer shot of the Bumpass Hell mudpots.
The hydrotermal activity is the result of water getting far underground to
a chamber of hot magma, where it gets heated up, and then coming back to the
surface. This process results into bubbling mudpots, steaming fumaroles and
boiling springs. There is a boardwalk going around Bumpass Hell. For your
safety it is advised that you keep to the boardwalk.
