Mud
After rain, the dirt would turn to mud. (PROSE: The Shadow in the Glass, Loving the Alien) Flooding had the same effect. This would make travel difficult, particularly on unurbanised soil. (PROSE: The Shadow in the Glass) Mud was slippery, (PROSE: The People's Temple) as well as sticky, (TV: "The Escape") to the point where one's shoe could get stuck in it. (AUDIO: The Paradise of Death)

(TV: "The Escape") Later, on the way back into the Dalek City, a swamp's uneven ground alternated between rock and thick mud. (TV: "The Expedition")
