Trekking in Garhwal
The optimal timing for our trekking trips is between May 1st and June 30th and between September 1st and October 15th. Both seasons have their attractions. During the month of May the spring flowers bloom at the margins of the snowline while the weather is generally settled barring the occasional pre monsoon storm that can blow up at any time. Day time temperatures can rise to the mid 20s even at altitudes while at night they can fall to 0 degrees C. The post monsoon season is a time of settled weather with clear views of the mountains. Day time temperatures will still be quite warm, upto 20 degrees C during the middle of the day, however at night the temperatures will occasionally drop below 0 degrees C.
Roopkund
Roopkund is a lake situated at a height of 5029 mts. in the lap of the Trishul Massif, hidden below a ridge on the periphery of the Nanda Devi Sanctuary. It is often called the “Mystery Lake”, as in it lie some 300 corpses dated to the 14th Century AD, well preserved due to the cold and only seen when the lake thaws. There are two versions for these remains; one, that they are the remains of soldiers under General Jorawar Singh’s army which was on its way to Tibet, the other that they are the remains of people on a pilgrimage to Trishul base about 600 years ago.
High-up in the Himalayas, the Roopkund lake, surrounded by rock-strewn glacier and snow clad peaks, is a marvelous sight. The starting point of our trek is Mundoli village situated in eastern Garhwal Himalaya. To get to this starting point all trekkers are required to initially reach Kathgodam by over night train from Delhi.
The Valley Of Flowers
In 1931, Frank S. Smythe, who was part of a team of six British mountaineers that climbed Kamet, came across a valley beyond Bhyundar Pass that had “lush meadows… embowered amidst flowers. The Bhyundar Valley was the most beautiful valley that any of us had seen.” Smythe in his book recalls that his camp was surrounded by a variety of flowers – primulas, white anemones, golden nomocharis, marigolds, globe flowers, delphiniums, violets, eritrichiums, blue corydalis, white roses and rhododendrons. Higher up, near the moraine, were saxifrage, yellow and red potentilla, geranium, asters and gentians, so many that “it was impossible to take a step without crushing a flower”
Today this Bhyundar Valley is not very different from how Frank Smythe first found it to be. Through strict environmental control and tight Government of India regulations, the sanctity of Frank Smythe’s discovery – the Valley of Flowers has been carefully preserved. If you stand at the foot of the valley, grassy meadows run down to the cleft of the stream, which, even in August, is still fringed by ice. On both sides, green slopes turn to dark rock as they vault into deep blue skies. Rising gently, the valley ends as notch on the horizon, crested by the snows of the Rataban (6,166m) and Nilgiri (6474m) peaks. And underfoot, the flowers that give the valley its name.
The Valley Of Flowers is accessible from a remote village in the Indian Himalaya called Gangharia. Getting to Gangharia is a small adventure in itself.
Nanda Devi Sanctuary Trek
It takes eight days to reach the base camp of Nanda Devi on the south side. The Rishi Ganga River forces its way through two gorges. The first one, near Lata village, cuts off any possibility of an easy approach, and therefore a route over two intervening ridges -the Dharanshi and Malathuni – was explored. Shipton and Tilman called this the Curtain Ridge. Near the second gorge of the Rishi Ganga a route was explored over precarious, rocky terrain.
The approach to the inner sanctuary will always be difficult. The route is: Lata, Lata Kharak, across Dharanshi Pass (4267m/14000ft) to Dharanshi Alp, across MalathuniPass (4270m/14010ft) to Dibrugheta Alp, along the river to Deodi, Ramni at the foot of the gorge, Bhujgara half way through the gorge and Patalkhan across the main difficulties of the gorge. 'The Slabs' are the first of the challenges, where downward-sloping rocky slabs make for a precarious crossing. A narrow staircase of stones ahead cuts across a huge wall. Just one slip and you would plummet thousands of feet down the gorge, aptly called the vaikunth seedi (the 'staircase to heaven') by locals. If you climb up this, you will reach the heaven of the Nanda Devi Sanctuary, whereas if you fall, you might reach heaven anyway. Patalkhan is the first halt in the sanctuary. From Patalkhan, the route crosses the Rishi Ganga to enter the north side of the sanctuary.

AMS-Explained
Early AMS
The earliest known account of mountain sickness can be traced back to the first few decades of the first century A.D. One account from the period reads, “The travellers have to climb over Mount Greater Headache, Mount Lesser Headache, and the Fever Hill, where they will develop a fever, turn pallid, feel a headache, and vomit." (Ward 1975)
In 1590 in Peru, a Spanish priest wrote of the ill effects of altitude while crossing the Andes and concluded, “the element of the air is so subtle and delicate, as it is not proportional with the breathing of man, which requires a more gross and temperate air.” (Heath and Williams 1981)
Theories of mountain sickness advanced rapidly with the popularity of ballooning in the eighteenth century and alpine climbing in the nineteenth century.
As man continued to push his physical boundaries by venturing higher and higher, he occasionally paid the ultimate price. In 1875, the flight of the Zenith from Paris resulted in the deaths of two balloonists, Sivel and Croce-Spinelli. However, this did not deter the early pioneers. This century's leap into aviation and space travel has brought with it a deeper understanding of human ability to function at altitude.
Onset of AMS
The incidence and severity of AMS depend on the rate of ascent and the altitude attained as well as the length of altitude exposure, the level of exertion and inherent physiological susceptibility.
The main symptoms of AMS are headache, fatigue, dizziness and anorexia with nausea also being common – in fact the initial symptoms are very similar to that of an alcohol hangover.
Where and at what altitude does AMS occur?
High Altitude is classed as 1500 to 3500m – AMS is common with rapid ascent above 2500m but does not tend to occur below this.
Very High Altitude is 3500 to 5500m – this is the most common range for severe AMS.
Extreme Altitude is over 5500m – any ascent without supplementary oxygen invites severe AMS. There is no human habitation above 5500m.
Himalaya: The Legend of the Chandratal and Surajtal
There is a charming legend about the famous, beautiful lakes known as Chandratal and Surajtal in the folklore of Himachal Pradesh.
The story goes that the daughter of the moon and the son of the Sun were in love. They wanted to meet, but this was very difficult as the son and moon come into the sky at different times. So, they decided to meet on Earth. They chose to meet near the Baralacha Pass.
Unfortunately, when they came down on earth, they landed on different sides of the pass and were still unable to meet. Their resultant great sorrow turned them into lakes of great purity. As their water swelled, they gave birth to two mighty rivers – the Chandra and the Bhaga, which flowed around the mountain range and were finally able to confluence at Tandi.
And the two lovers? They are said to be the two lakes we know as Chandratal and Surajtal, on the two sides of the fearsome Baralacha Pass, in the district of Lahaul and Spiti, in Himachal Pradesh in India.
It is said that the mesmerizing, haunting beauty of the Chandratal is a result of the beauty of the daughter of the moon – who knows? The whole ambience of the lake does seem to be out of this world.
The beauty and taste of crystal clear water, the crown of mountain peaks towering protectively, and yet keeping their distance, the soft, abundant grass, the serenity in the atmosphere, even the air seem to speak of magic.
This is one place you visit once, and just hearing the name takes you there in your mind for the rest of your life.

Everest Turning into World's Highest Cesspool
A deadly peril lurks on Mt Everest, the highest summit in the world, which is far more dangerous than the freezing cold, gale winds and recently posted security forces who are empowered to shoot at the sight of political activities. The new hazard comes from human waste scattered along the mountain slopes, which could run into hundreds of tonnes.
"Toilet paper and human excreta litter the Everest base camp (at an altitude of 6,400 metres), the slopes, and even the summit (8,848 metres) itself," says Ang Tshering Sherpa, chief of the Nepal Mountaineering Association, which is entrusted with promoting mountaineering in this country."In summer, when the snow melts, the frozen human waste comes into sight and starts raising a stink. The grave health and environmental hazard the untreated excreta pose is a matter of great concern," Sherpa added.
While conscious mountaineers have been trying to clear the garbage left on the mountains, nothing has been done so far to treat the human waste lying there.In the past, expeditions have collected used oxygen cans, tents, food tins and other litter and brought much of it down but the human waste remains."As it remains frozen during the expeditions, it is very difficult to remove it and bring it down," Sherpa said.In a bid to prevent the world's tallest mountain from turning into the highest cesspool, an expedition is now introducing, for the first time in the history of the Everest, bio-degradable toilets.
Sherpa's son Dawa Steven Sherpa is leading the 24-member Eco Everest 2008 expedition to the summit in memory of the peak's greatest benefactor, Edmund Hillary, to try and clean the garbage.The team is carrying three "Clean Mountain Cans" with them, a portable toilet manufactured by an American company. The bins are lined with bio-degradable bags that decompose the human waste deposited in them.The expedition is armed with 200 such bags. Besides using them, the team members will also try to remove the frozen waste on the summit, put it in the bags and bring it down to the base camp.The cans, which can be bought for $75 a piece in the US, cost a thumping $150 when brought to Nepal, one of the poorest countries in the world."The cans were gifted by the American Alpine Club, while some of the bags were donated by the factories that made them," Sherpa said.
Sherpa, who runs Asian Trekking, one of the leading trekking agencies in Nepal, said his company would henceforth use the cans and urge other agencies to employ them too.The expedition, that is also highlighting the dangers of climate change in the Himalayan slopes, is tying to put into action a banner in Kathmandu that urges citizens to use garbage wisely and turn it into money.It is offering each climber who brings down human or other waste down from the peak to the base camp $1 for each kg of junk.

Ancient Meteor Blast Peppered Mammoths With "Shrapnel"
Many of the animals, particularly in the region near present-day Alaska , didn't survive. That's the story being pieced together by a research team led by Richard Firestone of the Lawrence Berkeley National Laboratory in Berkeley, California.
The team had done previous work on a suspected impact that occurred 13,000 years ago. But while looking for evidence of that more recent blast in mammoth tusks, the scientists found traces of the much older event.
"The surprise was the tusks were dating back to 30,000 to 34,000 years ago," Firestone said.
"Nobody had thought of it before. It was serendipitous."
The work was presented this week at the fall meeting of the American Geophysical Union in San Francisco, California.
Tiny "Bullet Holes," Micrometeorites Found
While searching for evidence of the more recent cosmic impact, team member Allen West, an Arizona geophysicist, noticed an odd pattern as he was combing through thousands of ancient tusks.
He found that the top-facing sides of a few tusks were pockmarked by holes 0.08 to 0.11 inch (2 to 3 millimeters) across.
The pockmarks were found on seven mammoth tusks—most likely from near Alaska's Yukon River—and the skull and horns of a Siberian bison. (That the holes were found on only one side of the bones indicated that the impacts came from a single direction, Firestone said.
