Map of Khumbu-Rolwaling Region(courtesy: google)

The Solu-Khumbu is the district that houses Sagarmatha (Mt. Everest). the lower region is called Solu and the upper region from Lukla is referred as Khumbu region.
This region is of very histroical importance as most of the sherpas from this region took part in several Everest expeditions. Everest is located on the border of Tibet/China and Nepal. Until the International borders were defined the locals living there didn't care much about the nationality and lived on either side of these mountains/ranges; least bothered about to which country , which territory belonged. Mostly they owned most of these high lands and frequently crossed from one side to other.
The legendary Tenzing Norgey sherpa's story is also one such thing; He was born in Tibet and his family used to take yaks for grazing in the high lands on tibet side in shadow of the Everest region; Then they (family) migrated (fining good grazing ground s for Yaks) to Thame close to Namche Bazar in Khumbu region; they must have crossed into Nepal from Tibet through a pass called "Nangpa La 5806m". Then he travelled from Namche to Darjeeling for better employement opportunities such as offering him self as a daily labourer. The destiny had something special for this ambitious and strong climber. And his trumph on Everest along with Sir Edmund Hillary is a legend. After his ascent all Three nations - Tibet, Nepal and India vied to own his citizenship; Ultimately India respected/honored his achievement and opened a mountaineering Institute at Darjeeling (Himalayan Mountaineering Institute) and made him Director (Field Training). What Hillary got compared to Tanzing is phenominal.
Sherpa - a slight mdification from its original "Shar-pa" which means "people of East".
I am interested in crossing passes which are above 5000m in the region of Khumbu and its adjacent valleys such as "Makalu-Barun National Park" to its east and "Rolwaling" to its west.
Khumbu region connects to Rolwaling via the pass -
"Tashilepcha la 5755m". This is considered technical and to be dealt with lot of care according to climbers; More experienced trekkers treat it as dangers and not many parties attempt this in a year (about 3 probably); Once this pass was more frequented by the sherpas of Khumbu to reach Kathmandu on foot. Until Lukla airstrip came up, people must have used it more frequently but with Lukla airstrip and business prosperity in Khumbu region beaucse of tourist influx, shepras began to opt for easier and faster "Airway".
The other pass on the same line towards north sharing border with Tibet/China is "Nangpa la 5806". This is the same pass that was in news a couple of years back when Chinese soldiers shot the nuns/refugees crossing over from Tibet and trying to reach India to seek solace of Dalai lama;
Cho la pass 5420m: Connects Everest Base camp region and Gokyo lakes both of which are most visited/famous/favorite destinations among tourists visting khumbu region. The pass is considered not very difficult; Adviced to bring rope under snow fall/conditions; Though it's considered not very difficult several trekkers have succumbed to altitude sickness/hypothermia/exhaustion while attempting this. In 2008 when I was in this region there was an Indian party from pune/Mumbai who lost one of their members;
Renjo la 5340m: It lies to the west of Gokyo lakes, Very beautiufl pass (interms of views from top) also not very much frequented.
Mingbo la 5815: This is very dangerous pass; There is a overhang just below the summit which makes it very challenging; People attempting it go with a prep as good as attempting a peak. The pass lies on the flanks of Amadablam; This connects Pangboche of Khumbu region with "Honku Valley" on the other side of ama dablam adjacent to Amphu lapcha pass (by the side of Island peak).
Mera la 5415m: This is another no very difficult pass which leads to Honku valley; Trek ususal starts from Lukla; Those climbers approaching "Barun peak" take this route. Those adventurous trekkers attempting Ice col and Sherpani col and attempt to reach Makalu base camp as well take this pass; The other option is from Amphu lapcha la though.
I would be attempting some of these passes as first leg/part, mostly Tashilepcha la and Nangpa la; then proceed for Langtang, Manaslu, Annapurna and Dhailagiri circuts. After finishing these I would fly back to Lukla and attempt Mera la, Mingbo la, Chola and Renjo la. I did Renjo la last year so considering available time, I would make the decision. I am still exploring several options of executing it; though I made a good research and planned most of it; The plan is still lucid as I am still looking for spons.
