Old-timers here may remember a charming blog by Many Glacier's winterkeepers, a husband-and-wife team. Around 2013-2014.
They decided to retire from winterkeeping and start a family (though David Wilson may still be doing summer maintenance on Many Glacier Hotel).
They have produced a book about their adventures, with photos. Available by using the "Shopping" button under the header photo on their FB page:
