Perhaps you already encountered this photo before, as it became viral across the interwebs in the past few weeks. Can you explain why does the shadow of this volcano look like a triangle? The Mount Teide volcano itself does not have the strictly pyramidal shape like its geometric shadow might suggest. NASA explained it like this: “The triangle shadow phenomena is not unique to the Mt. Teide, though, and is commonly seen from the tops of other large mountains and volcanoes. A key reason for the strange dark shape is that the observer is looking down the long corridor of a sunset (or sunrise) shadow that extends to the horizon. Even if the huge volcano were a perfect cube and the resulting shadow were a long rectangular box, that box would appear to taper off at its top as its shadow extended far into the distance, just as parallel train tracks do.” Shot by Juan Carlos Casado and discovered by Jakub Kierzkowski who shared his discovery with us, the below spectacular photo shows Pico Viejo crater in the foreground which is located on Tenerife in the Canary Islands of Spain.
