Some great news to report before this impending cold snap. The Connecticut river has a thin but very good quality surface for Skating.
We skated probably about a mile above the Orford bridge, and then several miles below. The river surface consisted primarily of snow ice which was ranging from 1 1/2 to 2 1/4 inches in thickness. There was thicker 3 inch ice along the sidewalks near shore and surprisingly rimming holes of black ice which range from 2 inch down to zero.
The surface texture was primarily very good texture ice , With much of it the kind of texture that does not make noise under the skates but provides excellent traction. Also some sections of slush ice with topography and some sections of snow that had not fully wetted out. Also some sections of glass smooth sidewalks which were for the most frozen enough so you did not break through the over ice.
The major hazards were: open water, there were holes Of Open water, which are likely to become more frequent as you are heading north from the fairlee bridge. Recently frozen over black ice holes with very thin ice. Anywhere there was snow on the ice, the ice was very thin underneath. There were also some sections where the snow had recently saturated with water and gave the appearance of being the frozen Snow Ice we were traveling on, but was only a half inch thick. Most of these hazards should improve over the next 36 hours of extreme cold. There is supposed to be fairly consistent wind during this time so I expect that there will still be open holes as of Wednesday morning. I think good rules of thumb even for Wednesday morning would be don’t skate over snow, any black ice that has large grain Crystal texture should be tested( The black ice that was present today has a smooth slightly textured surface from the ice storm and should present similarly on Wednesday). Other than that all of the snow ice should be very thick by Wednesday morning as we can reasonably expect 2+ inches of thickening by then. Maybe more. It is certainly possible to skate the river tomorrow although it is predicted to be quite windy and never get above zero
Today’s river was a study in the power of current under thinning. The fact that we found the thickest ice in the center of the river surrounding week black ice holes was surprising. The general surface of the river was quite thin going down to as little as one and a half inches. My theory on this is that the rims of these holes allowed water up through to soak out the snow quickly during the snow storm a few days ago, while the rest of the river surface was covered with snow which had may be skimmed over (as I think it depressed the ice quite quickly ) leaving a layer of water between the frozen slush Surface and the ice below. This allowed underthinning to occur unimpeded as the under ice was insulated from the cold above. This also explained why the healed cracks in the river were stronger than the general surface immediately next to them. I have included some pictures below of the beautiful smoky dragon scale pattern that was created by the under thinning of the snow ice around these black holes, this pattern was an indicator of where the thickest ice on the river was.
Today was one of those wonderful days of ice reading Where you learn a little here , And a little there and then all the sudden a map of travel routes opens up before you indicated by the nuance of color, texture and pattern, my favorite! It was also a day where ice forensics (looking at the ice right in front of you to figure out how it formed )were important. To properly understand the river today it was important to really understand how the features in front of you had formed, skills in ice forensics Were crucial to this process.
In conclusion I would recommend waiting until Wednesday to skate the river.I think it would be safe to assume that by Wednesday morning it would be possible to skate from Wilder Dam all the way up through Bradford. There will be hazards along the way but I expect most of them will be passable either through careful ice reading or land portages. This represents possibly 35 miles or more of linear ice travel! Given the weather forecast this ice may last until Sunday, or maybe longer if we’re lucky with snow. There is potential for some snow showers this week but they are expected to be light. We scouted the river from above Bradford via vehicle down to the Orford Bridge. We have not seen the ice below East thetford so any additional info about that would be good.
