Quinn's Wenley Moor Cave Navigation Map
Quinn's hand-drawn map details a precise route through the Wenley Moor cave system to the Silurian caves, marking safe passages, Silurian locations, and escape paths for wounded comrades. The Doctor uncovers it in Quinn's office. Liz seizes it as leverage, threatening to expose the Doctor's secrets unless he lets her join the expedition. In the caves, the Doctor and Liz follow its lines exactly, skirting a lethal liquid barrier and Baker's spent cartridge and notebook to reach a smooth wall hiding the Silurian doorway.
