Pese a haberse formado hace apenas 600 años, el volcán está ahora cubierto de vegetación. No en toda su superficie, como se puede apreciar.

Carducci volcano

Eroded volcanic landscape. Approximately 15 million years ago this used to be a shield volcano (similar in structure to Hawai’i), but since its volcanism stopped the erosion has exposed the sides of the volcano. The most pronounced features are an ancient magma chambers. These would either feed magma to eruptions occurring on the surface or pulses of magma that did not make it to the top and have slowly crystallized at depth.

This wall-like feature is a left over from a plumbing system of an ancient volcano and is called a dykeordike. When this volcano was active, this dyke would have served as a duct through which magma was transport to feed the surface lava eruption, or alternatively it could have been an off-shoot from the magma chamber that froze up within a body of a volcano.

Now, ~15 million years later the erosion has removed much of this volcano and so its internal magma plumbing system is nicely exposed and is dominated hard crystalline rocks which are much harder to erode. Thanks to this contrast in erosion we have a beautiful landscape of the Warrumbungle National Park.

A camera found at a Goodwill store in Portland, Ore., revealed long-forgotten images of the Mount St. Helens eruption. 

Poas Volcano

A good 3,000 feet taller than Arenal is Volcán Poás, another active volcano in central Costa Rica. It has erupted 39 times since 1828 and has dual crater lakes near the summit.

The volcano’s 5,350ft peak is often banked in clouds—which doesn’t really detract from the view.

Irazú Volcano National Park

From the photographer: “This picture was taken during our road trip in Costa Rica, while visiting the Irazú Volcano National Park. From the top it is possible to see both the Atlantic and Pacific Oceans on a clear day. However, such clear days are very rare and it is typical for the volcano’s summit to be covered in cloud for much of the time. Although we did not have the opportunity to observe the beautiful view from the top, these clouds created a very mysterious atmosphere and made the landscape very photogenic."
