Milky Way over Devils Tower
Explanation: What created Devils Tower? The origin of this
extraordinary rock monolith in
Wyoming,
USA is still debated, with a leading hypothesis holding that it is a hardened lava plume that never reached the surface to become a volcano. In
this theory, the lighter rock that once surrounded the dense volcanic neck has now eroded away, leaving
the dramatic tower. Known by
Native Americans by names including
Bear's Lodge and Great Gray Horn, the dense rock includes the longest
hexagonal
columns known, some over 180-meters tall. High above, the
central band of the
Milky Way galaxy arches across the sky. Many notable sky objects are visible, including dark strands of the
Pipe Nebula and the
reddish Lagoon Nebula to the tower's right. Green grass and trees line
the foreground, while clouds appear near the horizon to the tower's left. Unlike many other international landmarks, mountaineers are permitted to
climb Devils Tower.
