I went just now to Dyatlov Pass.com and watched the drone footage of Boot Rock. I immediately thought that of an English and Russian captioned winter and summer movie was made starting at the labaz and termnating at the helicopter clearing where the bodies were taken, it would be such a help.
Maps are OK but limited. Still photos of the case files are hard to make out at times. It seems nobody has enhanced them through software. Since we are biologically equipped to see color better than black and white, colorizing the stills might be very revealing. Too, case files and anecdotal testimony are lacking if the reader has insufficient references or scaffolding on which to arrange, understand and interpret.
I know there are several dramatizations. The fault with them is that they are storytelling. That implies,a point of view.
