This hot spring is like a scenic view point!
The unfortunate thing is that the water becomes tepid being piped for a distance.
Muddy source of the springs
Long Valley Caldera in the State of California has many undeveloped hot springs inside it.
The Rock Tub is one of the most scenic places.
After entering Whitmore tubs road, soon turn right to the dirt road.
Usually it is very accessible.
I found steam on the right side.
This area becomes easily muddy after rain.
I finally found a structure.
In fact this mud pond is the source of the springs; water is piped to a tub around 150 feet away.
The water temp was 120 degrees F.
I noticed that the amount of water flow was not so large.
The PVC pipe clearly splits the snow ground.
I found the tub behind the small hill.
Volunteers have made it with cement and rocks.
When I visited in winter, water was barely being discharged from the edge.
In the spring two year ago, I observed higher water level and more water discharge; maybe the pipe got clogged.
Overnight camping is allowed around here.
The apparent custom is clothing optional.
Due to this, please do not park right next to the tub.
The size is for around five people.
Decorative tiles was found in front of it.
It was around 95 degrees F near the water outlet; 90 degrees F in the entire tub.
I felt it too cold for winter.
In addition, the water input was apparently insufficient to maintain it clean.
Maintenance has to be done in any ways.
Regardless of the defects, the spectacle from the tub was out of the world.
I would visit here periodically and confirm the conditions.
