ANECDOTE

Discovery Of An Untouched Living Cave

  • Robert Lamb and Joe McCormick describe discovering Karchner Caverns as an untouched, humid living cave found in the 1970s by Randy Tufts and Gary Tenen.
  • Tufts and Tenen squeezed through a grapefruit-sized blowhole after chiseling it open and found extensive rooms with guano from bats that had been the only inhabitants.

Small Human Traces Devastate Cave Ecosystems

  • Caves can be damaged by seemingly minor human actions like touching formations or leaving trash, which introduce microbes and disrupt humidity.
  • A single Cheetos bag or skin-lint can spur fungi, new food webs, and require decontamination, per the Carlsbad example discussed.

Bat Guano Forms The Cave Food Web

  • Cave ecosystems often rely on bat guano as the primary nutrient base, supporting fungi, insects, and entire food webs.
  • Removing guano for fertilizer or souvenirs can collapse those dependent food chains.
