What is "the guts of 700km"?

Without getting out an atlas, approximately 700km. But depending on the projection used, it could be as
much as 1000km, or as little as 500km. It does take 12 hours on a train (low priority, passenger), plus 4 hours
drive between the two sites, but since GPS is a prison-introducing technology, I'm not exactly sure if the road
route and the rail route are sub-parallel, orthogonal, or even anti-parallel.

Location: Muravlenkova Pad-2B, 64°01'15.8”N, 74°49'49.1”E ; Midnight Sun, no; 23:15 sunset, yes. Mosquitos ++

Location: 60°01'24.561"N, 70°59'23.103"E (Upper Salym)

The great circle formula from the "aviation formulary" (a long-gone site, but it's been accurate enough
for my uses for years) tells me those two locations would be 488km apart, if the earth were a close
approximation to a sphere. Which it is.
That's a shortest-line-between distance. Given that there are several major river valleys to follow and
cross in that distance, and a couple of watersheds to go over, something not far short of 700km sounds like a
good guesstimate of the distance between the two locations.
