By late morning the polluting smog that envelops the high plateaus and valleys around Mexico City rises and blocks out the view of two snow capped peaks that ascend to nearly 18,000 feet to the southeast of the capital city. Popocatepetl and Iztaccihuatl are respectively the second and third highest mountains in Mexico. These two peaks are part of the range called the Sierra Volcánica Transversal which extend from the Gulf of Mexico in the east to the Pacific Coast in the west. This range intersects with the southern end of the Sierra Madre Occidental and the Sierra Madre Oriental, two long cordilleras that run down either side of the country from its border with the United States. These three mountain ranges have been thrust up by tectonic plate action and where they converge immense amounts of subterranean heat are generated creating the greatest altitude of volcanoes in the country. At this intersecting plain also sits Citlaltepetl (Pico de Orizaba,) Xinantecatl (Nevado de Toluca) and Matlalcueyetl (La Malinche,) respectively the highest, forth and fifth highest mountains in Mexico. They too form the chain of volcanoes around Mexico City.
All these peaks are of volcanic origin, however, of these five peaks it is only Popocatepetl that is active and it is the volcanic activity that has brought about its climbing history. Before the arrival of the Spanish conquistadors, the Aztec emperor Moctezuma sent ten of his strongest warriors up the mountain to find the source of the smoke. Two of them died on the ascent while the rest reached the summit and saw the smoke belching from fissures within the crater. On the descent, another six perished from the cold, however, two managed to report what they had seen to Moctezuma but never recovered their pre-summit health.
The first European ascent of Popocatepetl happened in 1522 and marks the highest summit climbed by Europeans up to that time. The Spanish conqueror, Hernando Cortés, on his trek through Mexico, crossed the pass (Paseo de Cortés) between Popocatepetl and Iztaccihuatl and saw the Aztec capital of Tenochtitlán located where modern Mexico City is now situated. After his brutal conquest of the Aztecs, Cortés found himself in need of sulfur to replenish his supply of gunpowder. He dispatched a party of soldiers led by Francisco Montaño to climb Popocatepetl and obtain the material from the crater. They found the ascent trying due to the cold, temperatures they were not use too in the lower altitudes, but managed to reach the top. To acquire the sulfur, Montaño had to be lowered on a rope down the cliffs surrounding the crater. Despite his fears of falling and going straight to hell, he and his men managed to get hold of a supply of the badly needed yellow powder and return alive.
To the Aztecs, Popocatepetl is revered as one of the most important of their sacred mountains. Its rich volcanic soil combined with a congenial climate and plentiful water to make its lower slopes one of the most fertile and heavily populated areas of Pre-Columbian Mexico. The closer the maize grew to the mountain, the earlier it ripened and the better it tasted. Despite the mountains wrathful nature it represented to many Aztecs divine embodiment of all that was good and desirable.
The irony is that Cortés used a substance from the Aztec's sacred mountain to make gunpowder for killing people for the greater glory of the Spanish empire. At the same time the Aztecs performed their own bloodthirsty human sacrifices as a worship to the mountain.
In Nahuatl, the ancient language of the Aztecs, Popocatepetl means "smoking mountain" while neighbouring Iztaccihuatl means "sleeping woman." The close physical proximity of these two mountains has brought about a popular legend.
According to the widely held legend, Popocatepetl was a warrior of an Aztec tribe who fell in love with Iztaccihuatl, the daughter of the tribal chief. When the two lovers went to her father to ask to be allowed to marry, he told them he would only agree to their marriage if Popocatepetl would first conquer an enemy tribe and bring him the head of its leader. The young warrior succeeded in his mission, but he took so long that Iztaccihuatl, thinking he had perished, succumbed to sorrow. When Popocatepetl eventually returned triumphant, he found Iztaccihuatl dead, so he picked her up and carried her to the top of a mountain. He laid her along the summit ridge where she assumes the form of a sleeping woman - the shape many people see in the outline of Iztaccihuatl today. Popocatepetl lit a torch and stood watch over his lover, which accounts for the smoke that issues from the mountain that bears his name.
The ascents of Popocatepetl
by Moctezuma's soldiers and Francisco Montaño were not considered,
at the time, mountaineering feats, however, mountaineering as a sport
took on a new meaning in the mid 1800's with the ascent of all the big
peaks in the European Alps. Eventually, mountaineers began going abroad
seeking new adventures. Mountaineers such as Edward Whymper, Matthias
Zurbriggen and Edward Fitzgerald visited the mountains of New Zealand,
Canada, South America and Mexico making their mark with first ascents
of many previously unclimbed mountains. In the mid 1900's, with the convenience
of cheap air travel and the advent of modern climbing techniques and equipment,
contemporary mountaineers sought out the challenges of not only the lofty
Himalayas, but also many exotic mountains including the Mexican volcanoes.
These volcanoes have since become a popular destination, especially for
North American's, seeking their first taste of high altitude mountaineering.
Technically there is nothing difficult about climbing Popocatepetl and many people have reached its summit including the Argentine revolutionary Ernesto (Che) Guevara. Guevara made an attempt in July with some of his Cuban friends but returned and summited on October 12, 1955. For Guevara, who suffered severely from asthma, the climb, which to him meant the summit, was the ultimate challenge. It was to prove his strength of mind and determination. As a revolutionary, and a climber, Guevara had the "to the summit or bust" attitude that we see in a few strong-minded Himalayan mountaineers. For them the goal must be achieved. Death is a natural consequence that they are willing to accept as we can see in Che's writing in a letter to his mother on July 20, 1955:
In 1988 it was my turn to make an ascent of the famous volcano. On the morning of October 19, Geoff Mahan and I left our hotel in Mexico City and took a bus to the small town of Amecameca. After picking up a few last minute supplies at the local supermarket we then arranged for a taxi to take the two of us up to the hotel at Tlamacas. Tlamacas being a popular destination not only for climbers but also for Mexican tourists to see the volcano up close and to take short hikes on the lower slopes. Once at the hotel we enquired about the condition of the huts higher up on the mountain and found there was no water available. Since we didn't have containers for carrying any extra water we decided to take a bunk in the climbers hostel adjacent to the hotel.
Although Geoff and I had spent four months climbing throughout the Andes of South America we found that in the last month of traveling in Central America we had lost much of our acclimatization. That afternoon we went for a walk up the trail to about 4,500 metres to familiarize ourselves with the route as we would be leaving the hostel in the early hours of the next morning for the summit. That evening we cooked our dinner outside and stared up at the mountain with the usual excitement before a climb.
3 A.M. our alarms went off. We had not really slept due to the altitude
and our excitement but we were well rested. A light breakfast, a hot drink
and by 3:50 our packs were on our shoulders and with the aid of our headlamps
we began hiking up the trail of the Ventorillo Route. It felt good to
be back in the mountains climbing a peak that we had read and dreamt about
for many years. As we steadily gained altitude the dawning sun caressed
the eastern slope of the mountain while to the west a huge shadow in the
shape of the volcano materialized over the surrounding plains. At 4,630m
we passed the Quentano Hut and then at 4,900 we arrived at the Ventorillo
Hut. It had taken us three hours to reach the hut so we stopped for a
short break. Not far beyond the hut we decided it was time to take off
our running shoes. Climbing the scree trail was less tiring in our running
shoes but now that we had arrived at the frozen snow it was time to put
on climbing boots and crampons. Snow conditions were perfect as we gradually
made our way up the thirty-five degree slopes towards the summit.
Just before 9 A.M. we arrived on the summit and were greeted with an incredible view. The sky was clear blue and the outlines of Pico de Orizaba and Iztaccihuatl stood sharp and impressive. In the valley's below the smog was already beginning to build as Mexico City came alive. Having looked into many craters over the years it still never fails to impressive me when I look down into another one. Below the craters virtually sheer walls was another smaller crater and inside that one was a small blue lake. Belching out of fissures on the crater wall steam and smoke periodically shot upwards and the strong smell of sulfur permeated our nostrils. Neither of us talked about being concerned if an unexpected eruption from the Aztec Warrior were to take place. We were just basking in the glory of being on the summit of such a beautiful mountain.
After nearly an hour on the summit we decided it was time to head back down to Tlamacas. We discussed the two descent routes, the Ventorillo and Las Cruces, and decided to walk around the crater and descend the easy Las Cruces. We knew that we could have quickly descended the route we climbed because it was such a direct route to the summit but with it being only mid morning we chose to explore the mountain. After circumventing the crater we dropped down on to the Las Cruces trail passing many climbers still on their way to the summit. Although the path was very gentle and easy we kept thinking that it would have been an unpleasant climb because of the loose scree and the extra distance the trail takes as it winds around the mountain. Several places we stopped to lay down and rest and take in the view but by 12:30 we were back at the hostel taking on badly needed fluids.
Over the years since I climbed the mountain I have continued to follow the story of Popocatepetl and its increasing volcanic action. This stratocone volcano is one of Mexico's most active volcanoes and more than thirty million people live within view of the volcano. Major eruptions about 5,000, 2,000 and 1,000 years ago produced widespread tephra fall, pyroclastic flows on all flanks of the volcano and lahars that buried villages.
In 1992 the mountain began showing an increase in seismic activity and a noticeable increase in fumarolic activity in the summit crater. Throughout 1995 and early 1996, Popocatepetl produced occasional phreatic explosions accompanied by intermittent low-magnitude seismicity and anomalously high emissions of SO2. By the end of March, a new lava dome was identified in the summit crater indicating that a magmatic phase of the current eruptive episode had begun. Finally, on April 30, 1996, an explosion of the new dome killed five climbers who were at the summit and did not heed warnings that closed the volcano to climbers. They are the only casualties to date.
Over the next year occasional moderate eruptions sent columns of volcanic ash several kilometers into the air but on June 30, 1997, Popocatepetl threw ash twelve kilometers into the air during its largest eruption since 1925. The falling ash fell over Mexico City seventy-two kilometers away and caused the shut down of the international airport for fourteen hours.
Up until April 2003, Popocatepetl has continued to remain active. Pyroclastic
flows have halted eight kilometers from the town of Santiago Xalitzintla
and caused some melting of the summit glacier. Surrounding villages and
towns such as Amecameca and Santiago Xalintzintla have been on high alert
(Alert Level Yellow Phase III) and the road up to the Paseo de Cortés
and the hotel at Tlamacas has been closed. Those wishing to climb the
mountain have had to seek alternate destinations.
try to predict when the mountain will erupt using data collected over
the years and from studying similar types of volcanoes, but ultimately
the mountain has a mind of its own. Those living within reach of the outfall
are willing to accept the risk as they have chosen to live within the
shadow of the volcano. For mountaineers, the volcano will be continue
to attract a certain breed of climber fascinated with the challenge of
ascending the slopes to look into another summit crater and to play roulette
with the forces of nature. When Popocatepetl vents its anger, maybe it
is just the Aztec Warrior letting out a heavy sigh as he remembers the
loss of his beloved Iztaccihuatl.
