Trip Report – Karst Formations – 5 April 2017

Eleven of us took advantage of a break in the rainy weather to visit some of the Karst features on Quadra Island: sink holes, insurgences, resurgences, caves, and grikes – holes in the limestone surface which connect to the underworld.  Thanks to the recent rains there was plenty of water coming and going.  We also visited a horizontal mine shaft.  We don’t know what they were mining, but they made an impressive tunnel to explore.  Thanks to James and Carley, young geologists, for their interpretation and commentary on what we were viewing.
