A hot spring that bubbles up at the edge of a vast lava field.
It is located on private land that is just outside the boundaries of the national monument.
Craters of the Moon National Monument and Preserve
The largest basalt lava field in the continental United States during the Holocene epoch.
Crater of the Moon National Monument, designated as a national monument in 1924, is located approximately halfway between Boise and Yellowstone National Park.

It is estimated that intermittent lava eruptions occurred in the area between 15,000 and 2,000 years ago.
The lava has low viscosity and high fluidity, so it does not form large mountains, and the plains are covered in dark-colored rocks, which is said to resemble the surface of the moon, hence the name.
Geologists predict that the next eruption will occur within the next 900 years.
Stunning clarity
Route 26 runs along the northern edge of the Quasi-National Park.
15 miles west of the Visitor Center.
There was a parking space along the highway, and the entrance to Wild Rose Hot Springs was where a single steel pole stood.
It is slightly outside the boundaries of the national park, and although it is private land, it is not off-limits.
However, it is not hard to imagine that the landowner does not want this place to become too well known.
Please visit with respect and cooperate in taking your trash home.
A vertical shaft was discovered on the north side of the highway, which is thought to have been caused by volcanic activity.
Next to it was the Wild Rose Hot Springs, which contained clear water.
I found that the hot spring was gushing forth at the northern end, where the lava flow had stopped.
The swimming hole was made up of two pools of different sizes connected together, and there was a wooden pallet in the narrow center section.
Most of the water was gushing out of the smaller pool, and the overflowing water was filling the larger one.
The water at the source was lukewarm at 100 degrees F.
It was water of astounding clarity, with no taste or smell.
The water was about 5 feet deep and there was almost no algae, so it was a comfortable soak.
The other side of the larger pool was blocked off, and the overflowing water disappeared into the grass.
Now, I was curious about the footprints left on the ground behind the two pools, so I decided to explore them.
Then, I found another tiny spring that was just barely big enough to soak in.
The water temp here was 99 degrees F, and there was a cloudiness to it.
The clouds in the sky reflected on the milky white surface of the water, creating an indescribable landscape.
