sorry, I forgot to say- Ray's red arrows are numerous locations of elements of his unit at various times... not necessarily indicative of
119th visits, but could well have been, in that much was done in combat assaults, insertion/extraction, resupply, evac, etc., etc..
most of which I know nothing about, but would have given my wasted appendix and/or right arm to have done with the guys...
also, this page is likely only a small area of the valley, but institutional knoledge and hands-on experience from these guys will get you within about 10 meters on the map of the coordinates you have...
