The springs lie on a fault and it is likely that the breaks in the rock allow surface water to be heated and driven back from the hot interior of the Earth.
The hot springs are very primitive with mud and rock bottoms and are very shallow (waist deep when sitting).
These hot springs are not maintained by Olympic National Park or Clallam County Health Department.
During the summer months the water in the hot springs is stagnant and does not flush itself out sufficiently; consequently the pools are very likely to be carrying infectious bacteria.
Water quality tests have revealed high levels of disease bacteria in the hot springs pools after concentrated visitor use.
