So. Tunnels have been discovered under Antarctic ice.
Oh, sure, they appear to have been “formed from meltwater flowing underneath the ice, over land, and into the ocean”—at least to those blissfully unaware of the disastrous Pabodie Expedition of 1930–31.
“It is absolutely necessary, for the peace and safety of mankind,” geologist and expedition leader William Dyer later warned, “that some of earth’s dark, dead corners and unplumbed depths be let alone…”
Here’s hoping the British Antarctic Survey heeds the good professor’s words and lets sleeping shoggoths lie.
