Stuff that bored him then had now, suddenly, become loaded with significance. We buy our oil from the Soviets. They got a right to put in here. They started a mining concession. The Russians are flying in heavy equipment through Husavik. Right. Husavik was not far from Jokulsa a Fjollum.

And the lookout post beneath the glacier maybe one of several along the river's course was just a fail-safe precaution to make sure nobody stumbled on the secret.
