I already answered your question in my other indica origin thread :
Knowing that in real alpine elevation there’s no more trees so it isn’t from 2700, 2900 or 3000m lol but from probably below or around 2500m! So where IG did you find that pic and false info? TRSC? Not surprising because i think that this company spread a few inaccurate botanical things about landrace.
Also i do not consider as true pure sativa some places out of the equator or tropics. In higher latitude like in Nepal, Pakistan or Afghanistan i think properties and cannabinoids chemistry differ so not really Black pure sat there. I would say that it’s possible closer to Red but not really like in tropics or in more intense sunny southern hemisphere.
