Best Map I Have Come Across So Far Of The Himalayan Orogen

Looking forward to some travel in the Himalayas later this year and I wanted to brush up on some details of the geology. I tend to always get confused about the relationship between the major structural discontinuities with major stratigraphic and physiographic divisions of the Himalayan orogen.

Some time back I found a very detailed review published in Earth-Science Reviews by An Yin of University of California, Los Angeles. : Cenozoic tectonic evolution of the Himalayan orogen as constrained by along-strike variation of structural geometry, exhumation history, and foreland sedimentation

In it was a map I was looking for.

What I liked about it is that it covers the entire length and width of the orogen. The along strike variations in the major tectonic boundaries and stratigraphic units are clarified. Their local names are annotated properly along with the common names for the regions in which these geologic units fall. That is one of the major headaches of understanding Himalayan geology and this map does much to sort through the confusion.
