Highest unclimbed mountain peaks from subpeaks, there is no widely agreed standard. In 1994, the International Climbing and Mountaineering Federation (UIAA) classified 82 mountain peaks in the Alps whose summits were at least above sea level and with at least of topographic prominence over any adjacent mountain pass or col, as a distinct peak. It can be difficult sometimes to determine whether or not a mountain peak has been fully summited. Long before modern mountaineering commenced in the middle of the 19th century, evidence indicates that people did indeed travel up to the summits or near to the summits of major mountain peaks.
