Healing waters have always been a draw for people. At least half of the United States has geothermal resources—more commonly referred to as natural warm and hot springs. Depending on conditions deep in the earth’s crust, magma or molten rock can heat groundwater in some areas. A circulation process generated through rock faults can also generate heat that warms water. Water that rises up and out of the ground can be odorless and clear or sulfur smelling and tasting. It can even be naturally bubbly.
Typically, where there are hot springs, there are accommodations for the people who flock to them.
