Colliery Mine Navigation Map
A worn paper map of the colliery’s subterranean tunnels, its edges curled from damp mine air and held flat by calloused fingers as the participants study the network. The markings seem hastily added—a smudge of graphite from a mining pencil traces the sealed west seam in bold strokes, drawing immediate frustration from the Doctor. The map’s center shows the critical ventilation shaft and power house storage shed where Dave claims to have hidden rescue equipment, now circled with urgency. The paper’s thinness and yellowed creases reflect years of colliery use, each fold an old path deepened by oil and grime from miners’ hands.

Purpose
Navigation and planning aid used during mine operations to chart subterranean tunnels, identify key access points, and locate important infrastructure such as ventilation shafts and equipment storage.
Significance
This deceptively ordinary map becomes the focus of conspiracy as key routes appear obstructed or misrepresented, directly impeding the Doctor’s rescue mission and exposing deliberate sabotage within the colliery system.
