How devils tower formed?

A loooooooong time ago it was classified as a Stratovolcano. When it erupted, the magma cooled and hardened in the volcano. Eventually, the outer part eroded away, causing the cooled magma to be exposed. After that, it was then classified as an extinct volcano, and to this day it is a popular tourist attraction.
