The Volcano Tube Nico de los Jameos is a large tubular cavern, just over 6 km long on the mainland, which continues under the seabed for at least 1.5 km more. This underwater part is called the Atlantis Tunnel. The grotto with a linear trajectory, without lateral ramifications and which describes some not very pronounced curves, was formed due to the lava emitted by the La Corona volcano. To its great length, we must also add the great breadth that it reaches internally in some sectors, up to about 35 m high by 20 wide, normally reducing these measurements considerably in most of its route, not missing points in This causes narrowings that a person can hardly crawl through.

For its formation it is believed that in the existing terrain prior to the eruption there would have been a ravine that was invaded by lava from the volcano. After some time, the upper layers of the lava flow ended up solidifying in contact with the ambient air, thus forming a lava flow. a roof under which he continued flowing molten lava. Once the emission of lava ceased, the one that filled the tube ended. for being discharged into the sea, with which the tube-shaped conduit through which it circulated was left behind. empty, remaining like this finally formed the cave to solidify the walls and ceiling. This process should be repeated for the second time, because it is It is made up of two superimposed galleries with similar characteristics, although in many sections both constitute a single conduit due to the lack of the intermediate horizontal partition that separated them.

At the time of the formation of this grotto it happened, either due to the pressure of the molten lava flow that flowed through its interior or due to its descent when the ceiling was not yet open. So well petrified, that certain portions of it sank, leaving in the places where this happened two openings that exposed the interior of the cave that was under them. Many centuries or millennia later, once the cave had been definitively formed, new collapses of the ceiling occurred, all of them with a width equal to or somewhat less than that of the cave itself. The first of these ‘jameos’ They can be recognized by their blunt or rounded edges, as they are formed by lava that is still pasty, and the latter by clearly showing the sharp edges resulting from a breakage of the already formed rock. These large cavities, including both the hole opened in the ceiling and the section of tunnel that remains uncovered, are called jameos, a word taken from the speech of the primitive inhabitants of the island.

The ‘jameos’ that open on your roof along its path, listed from top to bottom, are as follows:

Collective name of the first three jameos or more close to the La Corona volcano, which caused the formation of the volcanic tunnel. They are even above Los Jameos de Arriba despite their name, a little more than 1 km SSE of the town of Ye, surrounded by sandy crop fields. They are called Los Molinos because they are in the area of this name.

They are close to each other and are called, from top to bottom, El Jameo de Seña Juliana, El Jameo de Tomás Ribera b> and The Jameo de Frasco Gómez.

The Jameo de Seña Juliana.

It is the higher up and, therefore, closer to the mountain of La Corona. Its shape is more or less elliptical, about 70 m long by 40 wide. Its walls are vertical, about 10 m high. At the western head, the volcanic tube is completely blocked and at the opposite it continues with a very narrow mouth for a few meters.

El Jameo de Tomás Ribera.

It is the second or central of the three. It has a somewhat oval shape, about 50 m long by 40 wide and 10 deep. The volcanic tube into which it opens is plugged at both ends.

El Jameo de Frasco Gómez.

It is the one that occupies the lower position. It is divided into two unequal halves by a pile of small stones that crosses it widthwise and forms a kind of slope on its S flank. Its length is about 60 m, and it is blind at both ends. About 100 m below it passes the main road to Ye.

Where is it

There are 4, close to each other, called the Town Hall, which is north of the road (Lzt-203) that divides them. On the other side we find that of Pablo Rodríguez, the most to the N, and those of Los Rodríguez the other two. They are located a couple of km SE of the town of Ye.

El Jameo del Ayuntamiento.

It is the first or located higher than four. Its shape is rounded, not very regular, with a length from N to S of about 30 m. Its walls, except in sector S where they are vertical, with a height of about 5 to 6 m, are almost in ruins. It is followed down, less than 20 m away, by Pablo Rodríguez.

A note of color that embellishes this 'jameo' is the large number of feral geraniums, normally in flower, that grow inside. .

It is called the Town Hall because it does not have a private owner and therefore belongs to the municipal corporation.

El Jameo de Pablo Rodríguez.

It is the second from top to bottom of the four of Los Jameos de Arriba. This jameo has been enabled in part for a wine cellar. To do this, a covachón has been used that forms between two smaller adventitious jameos that are like an extension of the larger one on its SE side, for which they have walled up the openings that said cave had with stone walls, in which they have opened a door and a window with their corresponding leaves. The room thus built is very spacious. The jameo mayor itself, irregular in shape, must measure around 50 m in length and a little less in width.

Los Jameos de los Rodríguez.

They are the two that are still below Pablo Rodríguez's a few meters away. The most northerly or located at the highest level of the two is almost round, about 30 m in diameter and its walls are vertical, with a height of about 5 m. About 15 m from this one, below it, is the other one, also round although somewhat larger, but as well as for its upper head or NOT it is high and vertical due to the opposite form of ramp of loose stones due to the collapse of the wall . Both are blind, without communication with the volcanic tube of which they are part.

Where is it

It is located 2 km SE from Ye village. We can find it following the Jameos de Los Rodríguez, which are about 350 m to the NW of it and a few hundred meters from another smaller jameo called Pende.

The Jameo de Francisco León is elongated, running from NNW to SSE, reaching about 70 m in length. Its depth is not great and in its S sector it is full of rubble and loose rocks.

A dirt track passable by wheeled vehicles passes through its head S.

Where is it

It is about 2 km SE of the town of Ye and a little less than 1.5 km from the La Corona Volcano. Is very striking, although small, not more than 12 m in diameter, rotund in shape, vertical walls and a depth of approximately 5 m in the center, because on each side in that follows the volcanic tube the central pile of stones descends in a ramp with great difference in height, the volcanic tube continuing on both sides with quite wide mouths.

Going up, about 80 m away, El Jameo de Francisco León and 1 km below El Jameo de La Gente, with which, according to people who they know this region of the island well, it has passable communication.

Despite the verticality of its walls it has on the O side some small projections in its highest section that act as steps, the rest of the stairs having been built with stones.

Where is it

This jameo is located just over 1 km to the E of the town of Máguez and 300 m to the NE of the main road that It goes up from the town of Arrieta towards Ye, at km 4.

It is one of the 'jameos' deepest, if not the deepest, of those that open in El Malpaís de la Corona, especially by its headwaters, since it must reach tunneling down a very steep slope on those sides more than 15 m high. Its floor plan is oval in shape, stretching from N to S. Its walls, high and perpendicular, only offer a place to descend, a crude natural staircase in its upper part complemented in the rest with some boulders placed by man that act as steps. to reach the bottom, on the W side.

On the north side there is a small subjameo inside, more than 2 m deep, through which you can access by descending into the volcanic tube that continues along over there. At the opposite end or S it is also aquevado, but the tunnel that continues at the bottom makes a sharp turn to the ESE in the direction of the Jameo de Puerta Falsa, which is 1 km away, with which it has direct communication, it is That is to say, without going through the jameos Tacho, Cumplido and Agujerado, which are in the middle, either because they correspond to an obstructed lateral diversion of the same volcanic tube or because the link is made through a lower gallery that passes below them, which seems most likely.

Where is it

This jameo is found unless 1 km to the NNW of the town of Punta Mujeres, about 35 m up from the Jameo Cumplido.

It is oval in shape, about 35 m long in an EW direction and about 25 m wide maximum, which is measured in its eastern half, on whose side it reaches its greatest depth, which is not very great.

Apart from this name of Tacho, which is the oldest known, some call it El Jameo Redondo, as well as Señor Florencio, which is the name of an owner who owned it not many years ago.

Where is it

It is less than 1 km NNW of the town of Punta Mujeres, between El Jameo Tacho to the W and El Agujerado to the E, both at a short distance from it. It is separated from the latter by a kind of bridge formed by part of the ceiling of the cavern that did not fall, about 45 m wide.

In accordance with its name, it is by far the longest of the entire series of these large cavities or subsidence of the land that exist in the Malpaís de la Corona, since it reaches a length of 140 m, with an average width of about 25 to 30 m.

Where is it

Se It is located a couple of kilometers NNW of the town of Punta Mujeres, next to the Jameo Cumplido, from which it is separated by a kind of natural bridge made up of a portion of the roof of the tunnel about 45 m wide that remained without falling. It is quite large, about 70 m long, but above all it has a considerable relative depth, since the height of its walls, which are very vertical, must range between 10 and 12 m, while its width is around 30 m. . At the head of the spring it is aquevado, with a very wide mouth at first, which then narrows inwards until it reaches the connection with the general volcanic tube, which is there with a somewhat square section, about 6 to 7 m high and a somewhat smaller width.

In the shady S part of this jameo grows in groups the endemic cucurbit of the Canary Islands called botanically Bryonia verrucosa and by the people of the island 'poisonous parsley', 'colombrillo', ' cojombrillo' or 'figs of the devil'. There, in that humid shade, its branches, similar to very long cords that can measure up to 20 m, cling to the rocks with their characteristic spiral-shaped tendrils, sometimes forming authentic tangles between the branches of other shrubby plants (gorse, berol and bobos).

Where is it

Also known as El Jameo de los Almacenes , is located a little over 1 km WNW of La Cueva de los Verdes. It is very easy to locate because it is very close, on the N side, to the tourist road that, starting from the N general road, goes down towards the aforementioned grotto, just where it describes its most pronounced curve.

This jameo is the second largest on the island, surpassing it in size only El Jameo Cumplido, which opens 1 km to the WNW of it. Its measurements are about 100 m long in the WNW-ESE direction by almost 30 in its widest parts. Its walls, which plummet down the sides, reach a considerable height, but this is greatly increased by its two headwaters, especially the one on the east side, where it must exceed 15 m, while the intermediate floor it increases in level due to the piling up of rocks produced by the collapse of the cavern roof when the jameo was formed.

The grotto continues along that higher head below, very wide at first, to suddenly narrow after a few dozens of meters of travel, then being reduced to a mouth only about 3 m high by as many wide that constitutes the old emergency exit of La Cueva de los Verdes, from which the name False Door comes. On its S side, at the point closest to the aforementioned road, it has a ramp down that is perfectly practicable on foot.

Where is it

Despite its small size, it is one of the most striking jameos of all those in the Malpaís de la Corona. Its upper opening is almost circular, only about 6 to 7 m in diameter, and then the walls, about 5 m high, retract in its lower half in almost its entire circuit, being considerably extra plumb in its upper part, of in such a way that below the floor, flattened and covered with small stones, it enlarges and gains quite a bit in amplitude with respect to the mouth.

Its formation is contemporary to that of the volcanic tube in which it opens, a condition that It is evident by the roundness and relative smoothness of the upper edges of the jameo as a result of the state of semi-fusion in which the lava in which it was forged was found, since if it had formed when the roof of the already petrified volcanic tube sank, the fracture would be quite evident. of the rock.

On the E side, taking advantage of the fact that the wall there, although quite vertical, nonetheless offers an inclination that allows the descent to almost half its height, they have made a rough staircase piling up stones on the ground that allows to save the rest of the inward-sloping wall until reaching the bottom.

This jameo is located 450 m WNW of Los Verdes and 160 from the road that goes down to the famous cave of his name, on a slightly hilly part of the land. And judging by the route that this tube-shaped cavern follows, it seems almost certain that this Jameo de La Vaca does not belong to it, since it gives the impression of being more to the N of it, for which reason, or it must correspond to another gallery of this very long cave that branched off from it, or belongs to another independent volcanic tube.

Where is it

It consists of a more or less circular hole, about 8 to 10 m in diameter at the mouth or upper part and somewhat less deep, which sinks into the rocky soil of the Malpaís de la Corona in the shape of a funnel, next to the to the road that leads to the Jameo de la Cueva de los Verdes and a little more than 50 m to the W of it.

The name comes from having a sign "like five fingers" on the back wall .

Where is it

This is the entrance to the famous Cueva de los Verdes. Its plan or figure is irregular and its size is rather small, with dimensions of about 20 by 15 m.

In the SE corner there is a large sunken or descending covón, called La Majada, about 8 m high and even wider that ends at the bottom in an enormous pile of stones and rocks on a slope that it obstructs the continuation of the volcanic tube in that direction. On the floor of this spacious attic, close to wall E, it was opened at the end of the 1960s, when the The cave for tourism, freeing it from the rocks that clogged it, the entrance to it, which gives access to the lower gallery.

The other mouth of the cave, the traditional Moorish Gate, connects with the upper gallery and is currently the exit, but formerly it was the main entrance to the famous Cueva de los Verdes. This second door opens in the NW corner of the jameo, being the opening that precedes it much less wide than the previous one.

Where is it

Also known as the Jameo de los Siete Lagos, it is located just over 200 m SSE from the Jameo de la Cueva de los Verdes. It is rather small, somewhat round, about 8 to 9 m in diameter, but proportionally very deep, about 10 m at least.

Its mouth and walls are somewhat smooth, which denounces its formation coeval with the eruption in which it formed. directly with molten material. On the E side it descends in a very inclined ramp up to half its height, from which level it continues to the bottom in a vertical direction like all the rest of the walls. It is on the S side where the tunnel continues. connected until arriving, after a certain route, at the underground lagoons.

Because of the discovery of these large pools produced by the tides that up to there let its effects be felt, they have been calling it El Jameo de los Siete Lagos ever since.

 

Where is it

Section of about 300 m long of the great Tube Volcanic of Los Jameos, distant 1.5 km from Punta Mujeres in a NE direction. The cavern of this name extends from El Jameo Redondo to the W to El Jameo Chico to the E, being between the two the largest of those that give it its name, in which the cave was built. the pool that is in this place.

In the beginning, when the grotto was in a natural state, before being enabled for tourism under the artistic direction of César Manrique, Los Jameos del Agua consisted only of the Jameo Grande or del Agua, in the chamber of the lagoon and in El Jameo Chico, through which the main entrance was later made. Once properly conditioned, it was opened. It was released to the public in 1966. Later, in the 1990s, the El Jameo Redondo, which is about 14 to 12 m in diameter and 10 m deep, and which communicates with At the back of the Los Jameos del Agua auditorium, they placed a large glass dome supported by an iron frame, and later an artistic stone staircase and some small flower beds with showy plants to adapt it to the general beautification of this tourist complex as a whole.

Regarding its geological formation, apart from what has been explained in this regard about the Jameos Volcanic Tube in general, of which it is an integral part, it should be added that it was also involved For this section of Los Jameos del Agua, the pressure exerted by the steam generated by the enormous heat given off by the still semi-incandescent lava when the seawater penetrates the grotto, exerting such pressure on its walls that after to bulge the ceiling came to open a hole in the top of it, making a piece pop out like a plug that was left behind. deposited right next to him as if it had turned on a hinge. He also must have During this primary phase, when the lava was still hot, the opening of the Jameo Redondo occurred, which due to its blunt edges can be seen to be contemporary to the process of formation of the cavern.

Where is it

Is the last or more close to the sea of all those that form along the great tube-shaped cave originated by the La Corona volcano, that is, the one that remains 'rear' or 'behind' of the Jameos del Agua. 

It is almost round, about 10 m in diameter, with an uneven bottom full of stones and rubble. By the head O is somewhat higher, on whose side it has two large holes separated by a kind of wide column or pillar.
