Jill Neate's great book "High Asia: An Illustrated History of the 7,000 Metre Peaks" provides a lot of information on each of the over 400 known peaks between 7000 and 8000 metres. It contains detailed summaries of their location, access and routes, together with descriptions of their individual histories of exploration and ascents.
The book was very helpful and one of the best available sources to create the 7000 m peak list. However, the list - influenced by subjective aspects - may contain inaccuracies and errors and remains a continuous revision.
Every red dot marks a place with elevations of at least 7000 m above sea level. The map is based on SRTM data
