Atlantic salmon fishermen regardless of whether they are on the Gaspe or in Iceland or the good ole Miramichi are always full of questions . My question today is why there is sand particles in the slush , as we Miramichiers call it . I have heard this ice formation called frazzle ice by people of “the know ” and some say that the slush is formed on the bottom of low fast moving water so it picks up sand from the bottom . I would like to hear from anyone that may have an explaination . I am most curious though of an event I witnessed app ten years ago when the entire river was full of perfectly formed baseball size solid ice . The following spring one could find piles of these ice balls along the shores for miles . I have only seen it once , has anyone else witnessed this ?
