The rock formation known as Shiprock, in the New Mexico desert, is a monadnock, or formation that rises alone out of a flat or gently sloping plain. It stands very close to the Four Corners region of the United States, the only place where four states meet at the same point.
The description states:
234 — SHIPROCK, NEW MEXICO
(SHIP OF THE DESERT)
This shaft of rock rising to a height of 1864 feet above the plain, dominates the landscape for many miles. The beautiful play of the changing lights on the rock are a source of delight to all who behold it.
From certain positions the resemblance to a “Windjammer” is very marked, hence the name “Ship of the Desert.”
–The rock is made up of volcanic material which cooled in the central pipe of a volcano, and was left behind when the rest of the volcano eroded away.
This postcard likely dates from the 1940s.
