The Zone of Silence

Everyone enjoys a good mystery and the natural world, despite the best efforts of scientists, still manages to provide a startling number of them. The Bermuda Triangle; the Dragon Triangle; the Brown Mountain lights; the list goes on. Here, in Mexico, there is another, deep within the scorching Chihuahua Desert. The academics call it Mar de Tetys (Sea of Thetys), but the rest of the world know it by another moniker: the Zone of Silence.



Thetys is a Greek goddess, who was seen as the embodiment of water. She was the sister and wife of Oceanus and the mother of the world's rivers. She may seem a bizarre choice to lend her name to a place of punishing heat and arid dryness, such as this part of the Chihuahua desert. However, in antiquity, there was a sea here. It covered most of modern day Mexico and the USA; and its legacy is the millions of fossilized marine creatures, which litter the desert today.



To say that the area has some unusual phenomena is to understate the situation. There are more UFO sightings, strange lights, alien encounters, ghostly figures and spontaneously burning bushes in this isolated part of the desert, than there are in the entire rest of the country. There is also some unusual flora and fauna, including a purple cactus and a sub-species of desert turtle, which aren't found anywhere else on the planet.

Back in the 19th century, local farmers were telling visitors about the 'hot pebbles' that habitually fell upon the wilderness. Modern scientists are still seeing them, but they are calling them tiny meteorites or guijolas.

Studies of the soil have shown high levels of magnetite. As the name suggests, this is the most magnetic of all of the Earth's minerals. This might give you a clue as to what happens to iron in the area.



Amongst the stories is that of a ranch, close to the Zone of Silence, which is regularly visited by two blond man and a blonde woman. To all intents and purposes, they are human and they speak perfect Spanish. What makes them so strange is that they only ever ask for water and, when asked where they come from, they simply answer, 'from above'. They are also wearing raincoats, which isn't common attire in a blazing hot desert.

The family on the ranch aren't alone in meeting them. A scientific researcher became separated from his party and was lost in the Zone. He was just starting to panic, when he spotted three blond haired people, wearing 'raincoats and ball caps'. They directed him back to civilization.



This is similiar to the experience of Josefina and Ernesto Diaz, a couple of fossil hunters, who got stuck after a rainstorm induced flash flood. This was on October 13, 1975, when their truck ended up in a hole, from which they could not simply drive out. As they surveyed the problem, they were approached by tall, blond men, in yellow raincoats, who suggested that the couple get back into their vehicle.

They did so and felt the truck being lifted and pushed back onto solid ground. Thankful and thrilled, the couple left their truck to shake the hands of the men. But they were now alone. The desert stretched for miles in each direction without a sign of their assistants. There were no footprints in the sodden sand.



A TV reporter also spotted them. Luis Ramirez Reyes was travelling with a photographer, in November 1978, with a view to investigating the area for a possible feature in a programme. As the two drove along, he saw three blond men, with raincoats, at the side of the road, watching them. The photographer was driving and, to the reporter's surprise, didn't stop the car.

As Reyes pressed him for a reason why, the photographer replied with incredulity that he hadn't seen then. This alone was enough to spook Reyes, but as they continued driving into a totally different part of the desert, he saw the same three men again, standing watching. As before, the photographer couldn't see them.

Travellers through the area often encounter the ghostly figure of a blond man, who just drifts across the road or is glimpsed walking across the landscape.



However, none of this is explaining why it's called the Zone of Silence. This is because no communication devise works there. Radio waves are randomly deadened. Cellphones have no signal; walkie-talkies just transmit white noise; televisions and transistors receive nothing but static; even compasses can't find north, but spin around on the spot.

This would be a harmless curiosity, but for the fact that it also destroys the equipment of anything flying above it. In fact, publicity for this place first leaked out after a pilot, Francisco Sarabia, crash-landed in the zone during the 1930s. He claimed that his 'plane's radio had stopped working, as he flew across.



Even more dramatic was what happened in 1970, when a US Athena missile left Utah bound on a test flight to New Mexico. However, the missile overshot its landing spot. NASA observers reported that it was as if the missile was suddenly pulled off course. It continued into Mexico and crashed into pieces in the Zone of Silence.

With the permission of the Mexican government, a team of US scientists and military crossed the border to the crash site. They discovered that not even satellite signals worked there. Short waves, radio waves, television waves, you name it, it was silenced.

These are just a few of the strange stories attached to the Zone of Silence. Many theories have been proffered to explain the strangeness of the area. They range from the spectacular to the prosaic, but none have definitely solved the mystery.

Protecting the Queen Conch at Xel-Há

There is so much to see and do at Xel-Há Water Park. It's billed as 'the largest natural aquarium in the world'. With all that there is on offer, tourists often miss that they are seeing something very rare indeed. This is the home of the endangered Queen Conch! Over-exploited by generations of fishing, this reclusive creature is on the very brink of extinction. Yet, armed with funding from the European Union, scientists from three continents have now arrived to see what they can do.


The Queen Conch (pronounced Konk-g) has fascinated humans for centuries. Their meat is a staple of the finer restaurants. It is second, in culinary popularity, only to the escargot, when it comes to edible snails. Nothing goes to waste, as every part of the conch can be devoured, though many profess to enjoying the 'white' meat only.

Their ornate pink shells often turn up in shops, bought to decorate private aquariums or to hang about in the garden. More prosaicly, conch shells have been used as home security, embedded into the top of walls, where the sharpened edges deter those thinking of climbing over.

Depictions of the ancient Maya have shown them using these shells as ink wells or bugles. Children of all ages still love to blow into the emptied shells, to produce a deep, resounding noise; or to listen into them to hear 'the sound of the ocean'.

Pink pearls are sometimes found inside these shells. They are destined to be fitted into beautiful jewellry.


The conch isn't known for its speed of flight. It's the original sitting duck, just waiting for someone to pluck it from the seabed and take it to its doom. As a result, the 'harvest' of Queen Conch has gone on unabated throughout all of recorded history. It's only as recently as 2003 that it was recognized how critically endangered it had become.

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) recommended that a blanket ban on the import and export of conch be effected immediately. Most Caribbean countries have complied. Domestically, there are also either bans or restrictions placed upon fishing Queen Conch.

In the Mexico state of Yucatan, the Queen Conch is protected at all times of the year. Next door, in Quintana Roo, fishing it is prohibited during the months of February through to October. Even during the rest of the year, only Queen Conch of a certain girth may be taken from the ocean.

For those tourists who have managed to purchase Queen Conch shells, or items made from them, then a shock may await them at home. In some European countries, these are the number one most seized items by customs. They take CITES recommendations very seriously.


Which leads us nicely to what is happening in Xel-Há Water Park right now. In 2009, staff at the park teamed up with academics from the Centre for Research and Advanced Studies of National Polytechnic Institute (CINVESTAV-IPN), based in Mérida. Their project is entitled, 'Protection and Preservation of Queen Conch (Strombus gigas)', and is headed up by award-winning environmental specialist, Dr. Dalila Aldana Aranda.

The aim of the project is to study the Queen Conch, discovering more about their biological cycle and the circumstances in which it thrives. Moreover, additional data about climate change can be gathered from examining the shells. The idea is to work out how to protect the remaining creatures and to help the species back from its critical state.

Recently, the European Union got on board. Their money has not only allowed the purchase of some important, but expensive, equipment to aid this research, but it's also been used to bring in more specialists. Australia's James Cook University and France's University of Western Brittany have both sent people trained in this field. Erwan Amice, Laurent Chauvaud and Thomas Stieglitz now work full time, under the direction of Dr Aldana.

Of course, for the rest of Xel-Há Water Park, live goes on as normal. Tourists jump off cliffs into crystalline waters; lounge on hammocks on white sand beaches; discover the jungle, on foot or on a hired bicycle; or vist the El Dorado cave, with its unique geological formations around a blue-green pool.

But for those snorkelling, scuba diving or sea trekking, in the open Caribbean Sea, then a glimpse of something very special might await. They might spot the Queen Conch waiting on the ocean floor, easily seen through those clear waters; or they could observe the academics at their vital work, studying and protecting this endangered species.

Next time you are there, keep a sharp eye open. Unless the project is successful, then you might be the last generation ever to see a live Queen Conch.

Spring Equinox at Mexico's Ancient Monuments

It is nearly dawn on the Spring Equinox and the crowds gather at the foot of El Castillo. They are about witness the descent of the God on Earth, as He passes down the steps and into the ground beneath. It is guaranteed. It is seen in Chichén Itzá every year and it is about to happen right now. An expectant murmur passes through, then a pause and suddenly an almighty roar of exaltation.


Spring Equinox at Chichén Itzá
It is only at the equinox that a stunning piece of Maya architectural genius becomes apparent. The side of the steps were fashioned in such a manner that, when the sun shines on them in a certain way, the feathered serpent God, Kukulkan, can be clearly seen. He is picked out in light and shade, with his snake-like back undulating down the steps. This can only be seen at dawn on the equinox.

Thousands traditionally congregate at the base of El Castillo (aka the Temple of Kukulkan) to witness this. Many will have been there all night, in a vigil, waiting. They are not all Mexicans. In fact, the vast majority are spiritual tourists, who have come to join their Mexican brothers and sisters, in this awe-inspiring event.

Kukulkan arrives to raptuous cheers; though many stand in silent meditation. All are allowing the calm, positive energy of the moment to penetrate their spirits. Traditional dancing and music soon turns the religious into a fiesta, as such things often do in Mexico.

Meanwhile, NTD TV have reported upon the events in Teotihuacan, near Mexico City: 'Thousands Flock to Mexico's "Pyramid of the Sun" to Welcome Spring Equinox'.



The Spring (or Vernal) Equinox occurs when day and night are exactly equal in length; there are twelve hours between sunset and dawn. The Earth, as it orbits around the sun, also rocks back and forth on its pole. (Imagine a spinning top, swaying as it spins.) During Winter Solstice (mid December) our side of the planet is tipped away from the sun (less light/heat = winter); during Summer Solstice (mid June) the hemisphere is tipped towards the sun (more light/heat = summer). During the equinoxes, we are at the mid-point between the two (equal light/heat = spring and autumn).

Spring Equinox was important to the ancient tribes of Mexico. It was the time when they planted their crops, safe in the knowledge that winter was finally over. Autumn Equinox was the signal that everything should be harvested, before it was ruined. This is why so much of the architecture incorporates features that tell onlookers when the equinoxes are occurring.

An estimated 460,000 visitors arrived at twelve of Mexico's ancient monuments, at dawn on March 21st, 2011. The actual equinox had occurred late the night before, but it was the dawn sun that would provide the first visible sign of it, without the aid of hi-tech equipment.


Spring Equinox at Teotihuacan
This is obviously an annual event, so everyone was ready for it. Representatives from the emergency services and National Anthropology and History Institute (INAH) meet months in advance, in order to co-ordinate their roles, so that the crowds can be safely managed. For example, so many people arrived at Teotihuacan, this year, that each had to queue for three hours, in order to spend just ten minutes at the summit of the Pyramid of the Sun. This had been anticipated and the human resources were on hand to ensure that this happened in good cheer.

However, there is concern that so many visitors are placing an unusual strain upon the monuments themselves. This year, for the first time, INAH issued rules, such as the prohibition of food, alcohol, barbecues, backpacks, chairs, umbrellas or pet in the vicinity of the ruins.

Meanwhile, local Pagan groups privately agreed not to climb upon those pyramids, which are open to the public. Antonio Vazquez, a Brujo Mayor (High Priest/Chief Witch), released a statement that his coven would be performing their ceremony near to the Pyramid of the Sun, rather than on it.


Spring Equinox at Tulum
The Spring Equinox celebrations are huge in Mexico. Many of those participating will either wear tradition costumes, based around Aztec or Maya historical designs, or else will don white outfits. The belief is that white absorbs the sun's enriching energies during this ethereal, beautiful time. It certainly feels very special to participate in such a gathering.

February 26th 2011: The Night of Stars

Festivites will be held throughout Mexico to raise awareness and enjoyment of astronomy. On February 26th, 2011, the Night of Stars will see organized events occurring simultaneously, across 30 locations dotted around the country. 200 institutions are involved, including the French Embassy and the Alliance Française network. The Night of Stars will be linking up with France, to render this a truly international galactical occasion.



The Night of Stars has been scheduled to coincide with both Jupiter and Saturn being visible to the naked eye. In the clear Mexican skies, Jupiter will be seen from 8pm, while Saturn will rise over the horizon from 9.30pm. This will also be a great opportunity to peer at the nebula, just below Orion's belt, where new stars are being formed.

Throughout the country, hundreds of professional and amateur astronomers will be on hand to guide newcomers with their star-gazing. There will be telescopes for people to peer through; as well as constellations pointed out, that can be seen without equipment.



Events also include lectures, workshops and exhibitions, all designed to introduce astronomy and educate attendees on their place in the cosmos. Of course, this wouldn't be Mexico, if there wasn't also a party going on. Cultural and artistic displays are also on the programme, though obviously nothing that will cause light pollution!

To learn more about the Night of the Stars, and to see what is happening in your location, then please visit the Noche de las Estrallas 2011 website. The English language version may be consulted with a little help from Google Translate: Night of the Stars 2011. All are welcome!


These festivities are part of Mexico's involvement in the International Year of Chemistry. As such, many of the workshops will concentrate on the chemical make-up of the universe.

Several other events will be held in Mexico, during 2011, to celebrate humanities achievements in chemistry. Please consult the official website for news on all that is happening.
