The mountain you see above is Mount Teide, an active and potentially very dangerous stratovolcano that towers 12,198 feet/3,718 meters over the island of Tenerife. Mount Teide is situated within the Teide National Park, located near the center if the widest section of Tenerife.
Most of the photos you’ll see today were taken at a vantage point overlooking an ancient lava field and crater within the park.
Near the vantage point inside the ancient lava field you can see a large, towering feature. This is La Catedral (The Cathedral). La Catedral is the remnants of a magma column once contained within a rising volcano. The slopes of the volcano have long sine eroded away, leaving behind the lava conduit you see on the right side of this image:
The surrounding area has an other-worldly appearance, and I wound up taking a lot of photos here. Below it today’s photo gallery. Click on any image to enlarge and activate the slide show:
