Hollow island of Palma

Very curious to get acquainted with conclusions to which he came. "The picture opens with Kumbre, no less majestic than the inside of the caldera. The traveler sees a chasm in all its grandeur, and hardly anywhere else on Earth's surface there is also a terrible abyss. Mid-caldera rises to 2,257 p., Lies slightly above the foot of steep cliffs, which form the cliffs more than 4000 r. Where can I find something like that? Where majestic cliffs surround this valley? Where the researcher sees with such clarity hidden beneath his feet? Individual ridges sharply nominated among the shaft and allow him to judge the composition of the whole. Everywhere, wherever you look kinesh lie layers of solid basalt, and powerful mass of tuff, volcanic bombs and lumps of slag. At the top of these layers is strongly inclined outwards and downwards slope makes them smaller, on the north side they fall to the north, south - south. One might think that an enormous amount of basalt veins, cutting through the wall from top to bottom, form a sort of ligament or bandages, which are fragmented and keep the masses in their position. Guess the more natural that the walls are mostly vertical or only slightly deviate from the plumb line. Downstairs in the barranco, these veins even more. The outer slope of the Caldera, as it were twisted toward the sea. Small barranco not visible or appear only in the form of small cracks, all other elevations are also visible, and slopes down almost evenly. This is a remarkable phenomenon affects researchers locality: when looking at the map of the island is easy to see how numerous barranco, going from top to bottom, but often the traveler, being close to these deep ruts, do not see them and even did not expect to meet until they do the latter step to the edge; barranco appear suddenly, a traveler has to go down the steep rocky walls 400 and 500 pounds. I climb down and then at the same height; further, by some four hours, he again encounters another barranco, just as steep and deep, even further - the third ... Only in small intervals between these giant potholes can huddle house. Streams coming down in the barranco, there, the water falls there only in the rainy season or during the melting of snow on the mountains. When climbing, even on a small height above sea level countless barranco make way extremely tedious: you have to climb up, then fall down, almost without moving forward. Therefore, local residents prefer to make traversal: they rise from Santa Cruz to Caldera, and then to descend to the Great barranco, they usually avoid the shortest path intersected by numerous deep potholes and gorges. Barranco diverge in all directions from the edge of the caldera. On the southern slopes Kumbre they are hard to come and reach the great depth only at the coast.
