In 1815, the German geologist Leopold von Bunch visited the Canary Islands and suggested that they were of volcanic origin. He also used the Spanish word caldera, meaning cauldron, to describe a few of the particular landforms he observed. The above is a later map of one of the Canary Islands, La Pama. The Caldera de Taburiente dominates the island and the map. The narrow canyon opening the Caldera to the southwest is called Barranco de Dolores [Valley of Sorrow] .
The topography of the island is beautifully shown using hachures. It wasn't until the mid 19th century that contour lines became the default way to show topography.
