Karst Terrain Surrounding the Duck Blind

A fractured, sinkhole-pocked karst field ringed around a solitary duck blind, where thallium-rich bedrock and hidden caverns stitch the ground into an irregular, treacherous tapestry. Damp air carries the hollow echo of subterranean rivers; sudden voids gape with black mouths, and the surface hides complex cave networks that scatter footprints and scatter sensors. The terrain actively masks biosignatures and complicates rescue and detection, lending the area a claustrophobic, uncanny menace and forcing agonized strategic choices.
