This unique rock formation of columnar basalt is known as Devils Postpile, and is located in eastern California near Mammoth Mountain within the Ansel Adams Wilderness. In the early 1900s, John Muir and other influential Californians persuaded the federal government to protect the site (due to the unique geology in the area) when a proposal to build a hydroelectric dam called for its demolition. Thankfully, they were successful, and the area now known as Devils Postpile National Monument received federal protection in 1911. Devils Postpile got its start much earlier, though. Roughly 80,000 to 100,000 years ago, hot basaltic lava began filling the Reds Meadow Valley north of the Monument.  Basalt lava has a lower viscosity than other types of lava, allowing it to flow much more quickly. So, a river of lava flowed down the valley until it reached a natural blockage. The hot lava rich in iron and magnesium began to pool, forming a lava lake up to 120 meters deep. As the lava lake cooled (somewhat uniformly), contraction stresses developed because solid basalt has a lesser volume than its liquid form. To release the internal stress created by cooling and contraction, a ‘cracking’ process called “jointing” occurred. At Devils Postpile, jointing formed the hexagonal columns for which the location is now famous.

Woah, another thing involving maths.
