the same parking lot to the Ridge Lakes, 2 miles out and back (1,000 ft
This area was
not hurt by the Dixie fire.

When hiking Cluster
Lakes loop hike, I saw a Bear, he was relatively far and running away from me,

When Hiking be Bear
aware and stay safe, for more information:
My thoughts: When I visit
the park Bumpass Hell trail was still close because of the snow so this was the
only place I saw up close the hydrothermal activity. It is interesting to see
the bubbling mud pot and steaming vents so up-close.
I arrived here
late at the afternoon with only one more hour before sunset, after the 5
minutes visit at the mud pots I still had some time to hike, so I decided to
hike up the mile long trail to Ridge Lakes.
along the main park road, Sulphur Works gives you a good glimpse of the roaring
steam vents and volcanic-gas vents known as fumaroles as well as boiling mud
pots. You will clearly smell the strong rotten egg sulfur steams and see the bobble's in the small mud pools.
This are in the
middle of an ancient volcano called Mt. Tehama that towered 11,000 feet high
half a million years ago, about five miles below the ground you can find today
giant pool of magma that heat up the surface, boil the underground water and
create all the hydrothermal activities.
Mathias Supan, started a sulfur mining operation for a variety of products,
including medicinal ones. As sulfur mining became less profitable, the Supan
family appealed to the tourist crowd with mineral baths, a restaurant, and a
souvenir shop. The National Park Service acquired Sulphur Works in 1952.
Ridge Lakes Trail:
The Ridge Lakes Trail climbs directly from the parking lot up for almost 1,000 feet in a mile.
