For those who like maps, my guess is we’re in or around Maiko NP (https://www.maikonationalpark.com/) in the Democratic Republic of the Congo. Here’s a fun little travelogue:
While Virunga NP to the east has had more news around guerilla violence of late
(and https://www.gonomad.com/1002-gorillas-and-guerillas-in-the-democratic-republic-of-congo), it’s in a more populated area, along the Ugandan border, less suited for Hidden Ancient Temples. Maiko NP sounds a bit more isolated.
