Entrance pit temperatures respond very quickly when atmospheric conditions are appreciably colder than existing air in Crowder Cave; temperature trends in the two rooms seldom lag more than 1-3 hours behind. Despite similar timing, the amplitude of temperature response in the large room is markedly less than in the small room, presumably because of a 35-fold difference in room volume. The amplitude of temperature change decreases and mean temperature increases with distance from the mouth of the large room. More characteristic of typical cave conditions, temperatures near the end of a narrow 85 m long side passage varied little (9.8° to 10.6°C) over the last 4.5 years. Crowder Cave data show the interplay between density-driven cold-air flow, karst topography, and cave geometry lead to variability in winter conditions that may give rise to very different bat hibernacula conditions in a single cave. The ecological significance of cold air traps associated with sinkholes may be profound, both as climate change indicators and for a potential role they may play in the course of the ongoing white-nose syndrome (Pseudogymnoascus destructans) epidemic.
