In reply to Kat4kgb:
For the Baltoro and close nearby, the Polish sat map is best. Made by Gregor Glazek of the Polish Mountaineering Association and GeoSystems. Published by PZA, 2004. It's b&w but with all peak names and glaciers overlaid on a large sat image. Stanfords used to sell it.
The two-sheet Swiss map is the only other decent one I know of. The Leomann maps are not only basic, they have a sufficient number of errors to be too misleading, maybe even dangerous, for actual routefinding. The old Soviet maps are quite accurate, and comprehensive, but even if you read Russian they are inaccurate in terms of roads, tracks, villages etc. and of varying scale, depending where you want.

But those maps have not, nor will be, ever improved, as none of them beat Google Earth and a good colour A3 printer.
