One of the enigmas of travelling in the Himalayas is that the higher you go, the wider the valleys expand. The snow- eroded slopes are steep but even. There are vast vistas of space and everything is far out in the distance. The feeling is that of expansion rather than being hemmed in.
However, somehow all my trips to high altitudes have been shortcuts. I have ascended up Himalayan heights ascending to an altitude of 4000 meters or more, propelled by an aircraft.
So too with Ramche in Eastern Nepal where a Mi-17 helicopter dropped me and two dozen army men on a vast valley floor. Ascending so quickly from Taplejung -a shabby Nepali village- I stood for several minutes, gasping the oxygen depleted air in awe.
Who would have imagined this idyllic pastoral hideout up in these virtually inaccessible Himalayan heights? But as I explored, I found one vast valley tucked behind another. Dotting them, herds of yaks grazed on the sparse short grass. Glacial streams snaked in the valley from everywhere forming a sort of estuary at the Ramche lakes.
Ramche at 4300 meters is far above the tree- line, with treeless mountains. However bonsai version of rhododendron grows thickly on steep slopes. It is an aromatic shrub, which the nomadic shepherds, the only humans who live in this part of the world, call sunpati. They use it for incense in worship. The other bush that grows on the mountains is juniper. The yaks don’t feed on the leaves of these plants -perhaps due their aroma; they instead nibble on short grass wherever they can find it.
The mountains themselves rise almost abruptly at the edge of the valley floor. Beyond them loom some of the famous Nepal peaks.
I was accompanying a team of hardy Indian Army mountaineers who focused on their goal ; summiting Kanchenjunga peak, had little time for mountain romanticism. For them Ramche was just a convenient broad strip of land, perfect to land the helicopters on and to pitch tents and stock supplies for the expedition.
One must rest at least a day after a sudden jump from low altitudes. But at Ramche, with so many spectacular bounties on display, I did not think I was any worse for wear. There was a low mountain wall that ran along the length of the valley to the east. No sooner we arrived , there was enormous curiosity on what lay beyond this wall. The Sherpas said there was a glacier.
This juniper-clad mountainside was a mere hundred meters tall but not sufficiently acclimatized, I was badly winded by the time I reached its rim.
But where was the glacier? Unlike Greenland, Iceland or Alaska, much of the Himalayan glaciers are buried under heaps of mountain debris. From a distance you only see the moraine of dry stone-strewn valley. But the Sherpas pointed out to us the snot-green glacial pools. We were looking at the Yalung glacier. Even with our layman’s knowledge we could see that it was a glacier in retreat. Further down the valley the mountainsides carried the scars of the once-flowing glacier ; lose earth and gravel was scratched with layers exposed in lateral patterns.
But further up the mountains, which we climbed the subsequent week, we saw the Yalung glacier spread out lavishly. However again, the crevasse-riddled surface was peppered with glacial pools, a sign that the glacier was melting faster than it should.
Himalayan glaciers present a big challenge to climatologists and glaciologist because of the inhospitable terrain.
“Compared to other parts of the world glacial monitoring in the Himalayas has not been done It’s a tough inhospitable terrain. The cost of study here is substantially higher. The glaciers are in retreat due to climate change but we need a lot of sustained research to estimate just how much”, says Ugan Manandhar, WWF, Climate and Energy Program Director.
Though the Intergovernmental Panel on Governmental Change (IPCC) has debunked the claim that all Himalayan glaciers will disappear by 2035, its a fact that many Himalayan glaciers have a rate of retreat of over 10 meters every year.
As we explored Ramche and its nearby areas we saw glacier snouts spouting water from under them in broad steady streams..
Today, however, the Ramche lakes are innocuous beauties. They are shallow and on a clear morning sky, they reflect the surrounding 7000 meter plus peaks in their blue ripple-less waters. A magnificent sight especially when the grunting yaks ford across it in herds.
But should the glaciers melt continue at the present rate, it will be lakes like these that will spell disaster. Fed with unrelenting glacial water they will soon metamorphose into large natural dams. After a point their weak banks unable to contain the enormous water will break, wrecking unimaginable disaster in their wake.
How to get there: By Air: Fly to Katmandu. From Katmandu fly to Biratnagar. From Biratnagar fly to Sukhetar in Tapleyjung. From Tapleyjung one can trek up to Ramche.
By Road– Cross Nepal from Siliguri. Drive to Tapleyjung 17 hours away. From Tapleyjung one can trek to Ramche.
fine post,it is useful to me and others,please just keep it on….
