Do you know what a lava tube is?
Sometimes a lava flow creates caves.
In case of low-viscosity magma, being exposed to the air, the external side becomes hard and the central portion flows outwardly.
Inside the cavity made though the process, hot springs are gushing.
Meadow Lava Tube
At the middle point between Salt Lake City and Las Vegas, there exists Black Rock Desert Volcanic Field.
The only thing you see is just the rocky landscape and no typical volcanos, which means the low viscosity of magma.
Such a basaltic lava flow sometimes creates lava tubes, and it shows that the volcano is geologically new because of the fragile structure of caves.
The eruption around here is considered only 1,300 years ago.
Lava Tube in the Great Basin
It is 30 minutes’ drive from the giant cave, Meadow Lava Tube to a parking lot in the meadowland.
Three hot springs are gushing within walking distance.
The trail is muddy and it seems like impossible to find clean hot tubs.
Suddenly, you will see a large pool.
The water temperature is tepid, around 95 degrees F, and 20 feet deep at a maximum.
The pool is not directly located on the meadowland.
Hot springs water is gushing inside the rocky lava tube, so that it looks crystal clear.
Since many people were enjoying in the first pool, I moved to the second pool in the back.
The water in the gourd-shaped pool was a bit cooler and looks more transparent.
The area between the Rocky Mountains and the Sierra Nevada is called the Great Basin.
No rivers flow from this basin to the ocean.
Shower of rain has to either evaporate or leak in the ground, and a part of it appears again above soil.
The magma that created the curious geography in 700 years ago still heats up the water in the outdoor bath.
