Detailed Description

Insights from southern Sierra Nevada caves and karst

By John C. Tinsley, Geologist
 

  • Water long ago carved many caves in carbonate rocks of the Sierra Nevada
  • As the Sierra (John Muir's "Range of Light") was uplifted, successively deeper caves were drained and decorated during the past 5 million years
  • Vertical arrays of caves document the progressive uplift and erosion in Kings Canyon
  • Lilburn Cave, with 21 miles of passages, is California's longest
  • New spectacular and pristine caves are still being discovered as recently as 2006
