In 2005,  John Belleza embarked on the 45-day long Tibet Upland Expedition (TUE), in order to survey sites across the breadth of much of Upper Tibet not reached on earlier campaigns. By continually making forays,he was able to close the gaps in the geographic coverage of the region. Slowly but surely,  John Belleza had now visited most of the major basins and valleys of Upper Tibet south of the 33rd parallel.
