[Rockhounds] strange rock on coast to coast am site

[Mr EMan]

That occurred to me after I posted, Earl. I am used to them when they
hit water and wash out a hole in the side --DUH.  Yes this is probably
injected bentonite/slury for lubing and shoring up the sides before a
casing was put down.

Good call!
