Even more surprising of the large CC digging into the pond bank, they dug through a 6"-8" thick layer of limestone stones with diameters of 1"-3". The cavity dug by these CC was about 14"-16" diameter. I stuck my boat paddle into the opening. The pond owner said he catches CC by fishing in the opening. I do not know how many years they had been using this cavity. If it was several years old it was likely enlarged a little each year. If I think of it this summer, I will revisit this pond and get more information and maybe some pictures. The top of the cavity was underwater about 16".
