Rocanville, Saskatchewan, Canada
I believe that this is a stalactite of halite. It is pretty, consisting of several lines of intergrown cubes of white halite. The attachement point is not obvious in that there is not a clear breakage point, but one end (the only end to show any damage at all) must be the starting point of the stalactite, as the lines of crystals appear to flow from there. Careful mounting will yield an impressive specimen.
