Ground Water Under Ice Streams

Shelburne Pond is one of our most popular skating ponds.  It is located in between two limestone ridges.  They dip to the east at about 15 degrees. Occasionally we find bands of thin ice a couple feet wide and  50 to 100 foot long.  This year we found four of them. 

About 20 years ago I found a peculiar narrow bit of thin ice that stuck about 100 feet out into Shelburne Pond in Vermont.  I have looked for this ever since withouit success.  I got the following from Doug  on January 29, 2017
