Great story, liked how it mirrored Solschenitzyns stories about dissident intellectuals in communist Soviet, and the almost tender portrait of these weary men determined to create a somewhat bearable life in a truly fringe environment. It's nice with a story that doesn't adhere to closely to the Hollywood dramaturgy. As a non-geologist, I didn't care too much about the temporarily misplaced geological markers, specially since they were not really essential to the main points of the story in my eyes.
