19940710-0928ac Devil's Tower National Monument (Lava Extrusion)
The remains of an ancient volcano which has lost its softer cone of cinders by erosion; Only the hard lava extruded before its collapse is visible nowadays and it is very high and spectacular; Some sports men climb it but it is very dangerous as large tubes of lava collapse sometimes and also as it is said that in the meadow standing on top, there are many rattle snakes waiting the imprudent visitors; Perhaps a legend but rattle snakes are very frequent in the area!
