While capturing the spirit of the place, the article falls victim to stereotypes, such as “abandoned Soviet-era aluminum smelter”: if it is “Soviet-era”, it has to be “abandoned”, like “a nice hot” fits together with “a cup of tea”.
Also, I couldn’t make sense out of the episode of a man with a gun chasing the traveler away. It sounds like the author stumbled into a military base, but there are no military bases in or around Kandalaksha. The only plausible explanation I can think of is that the author of the story happened to stumble upon a dacha owner overprotective of his property. Highly atypical I’d say.
