In Fall 2010 I went on a Himalayan mountaineering expedition to a remote part of NORTHEASTERN NEPAL (the Yangma Valley)
The trek in to base camp was an adventure in itself.
We then attempted to climb an unclimbed 21,500 foot peak - two of our group summitted.
An account of the climb appeared in the New Zealand Alpine Journal 2011: click here
Another account is at the American Alpine Club website: click here
I have posted many photos of this Himalayan trip.
