Shiprock in the Northwest corner of New Mexico
represents the remains of a highly eroded volcano.
The central peak is a volcanic neck that was once the main conduit of lava up to
the surface. Surrounding
the volcanic are impressive radial dikes that were at one time radial fractures
in the volcano that were
filled at a later time by a more erosion resistant magma. Extensive
erosion removed all traces of the
earlier volcano except for the volcanic neck and impressive radial dikes.
The feature is so striking and
unusual that it inspired the topography used in the movie, "John Carter on
base map, showing the location of Shiprock
Zooming in closer, Shiprock is located between the Four Corners area (where Arizona,
New Mexico, Colrado
and Utah meet) and Farmington, New Mexico.
In this view three dikes radiate outwards from Shiprock. Two of the dikes
are very prominent and the
third is narrower.

By using the tool from Google Earth that allows you to tip the

(Also, there is no chance chance of your airplane crashing.)
This view from Google Earth is much better than the the photograph I took from a
small plane flying
