Day 2,095

When the glacier retreated we were too busy to notice what it had left behind barely buried beneath the till. Years later geologists and glaciologists would wonder why there were gaping holes in the ground and what could have caused them.

Coincidentally all nearby settlements relocated several dozen miles away from the glacial anomalies, all in the same silent agreement that they wouldn't talk about what they'd seen. They wouldn't have been believed without proof and nobody was willing to go back there long enough to get any.

Eventually, after a handful of geologists vanished, the area would be declared to be resting on unstable ground and all missing persons would be deemed lost. It wasn't that they were lost, more that their bodies were in such a precarious place that they might as well be lost.

And that's saying nothing of the drag marks leading into the holes, the sparse bones that were freshly picked clean a few metres within and the overwhelming stench of blood lingering around the whole area.  If there were any survivors they were somewhere deep beneath the ground, deep in a vast warren that predates anything mankind has ever done.

And that's where they'll stay, more cost effective to declare them dead than start a manhunt.

Whatever was sighted around the anomalies didn't wander far enough to be anyone else's problem anyway.
