An earlier thread on the lake freezing talked about ice shards sticking almost straight up in areas around Rattlesnake. Also, driving on Rte 11 back then, I noticed what could have been shards off of Ames Farm, and also in Alton Bay both by Echo Point and then down by Sandy Point. They seemed to be caused by thin sheets of ice forming which were then destroyed by high winds. Finally we got the one good cold snap we needed, and that froze the ice solid, and left these pushed up shards.
Now we have had snow, and quite a bit of it. There may be some pressure ridges under it along with the shards.
Not being an expert on pressure ridges ( I know not to hit them, if at all possible

), but with the consistently cold temps, no thaw, perhaps there is not the movement of ice plates like we have had in the past few years.
Just a thought.
