Cotopaxi in Ecuador
This image was taken on Feb. 19, 2000, by Space Shuttle Endeavor as it mapped elevations on the Earth’s surface. Mount Cotopaxi is prolific in its eruptions, having done so as many as 50 times since 1738. Of the image, “blue and green correspond to the lowest elevations in the image, while beige, orange, red, and white represent increasing elevations,” writes NASA. Located in the Andes mountain chain, Cotopaxi is known as the world’s highest continuously active volcano.
