The Endellite field of the Clays section should list stations where endellite is found.

Endellite is an aluminosilicate clay mineral which has been transformed by sulphuric acid from montmorillonite. Geologists usually know it as "hydrated halloysite"; but, speleologists still use the term "endellite". It is often found associated with montmorillonite. It is usually bluish in color but the color can range from white to deep blue or green. It is waxy and looks something like candle wax or soap. It can appear under breakdown or scattered in sediments. Look for it anywhere clays may accumulate.
