A Little Snow on the Ice and an Eagle Is Back

Presently, it is snowing, the forecast Saturday snow. Probably not enough to make it really skiing friendly but will cover the patterns on the lake ice. Some of ice patterns are wonderful….. On walks around the lake, on two previous days, an eagle was on the nest tree. Looks like we may have another nesting season. They lay eggs near the end of March.The picture of the eagle is from this year although he/she looks the same as last year. ???????????????????????????????

Out on the lake, there were lots of things to see. Some of the old drifts had soaked up enough water to be basically solid but didn’t quite melt into the rest of the water on the lake and form ice. This “snow” covered maybe 1% of the surface, maybe less. Old ski-mobile tracks, where they had been driving on the crust and broken through that layer froze with ice chunks, are now preserved for the season.

??????????????????????????????? ???????????????????????????????But around some of the bigger rocks or in some places that typically have open water all through the winter, there was a bit of open water. Below is a picture of a “lead” (or open water in a lake or ocean.) A lead typically forms off the west end of Stamp Act. It occurs because of pressures associated with expanding and cooling of the ice and winds. Even though there is 8 inches or more of ice in most places on the lake, you still have to be careful. Now, with snow on the lake surface won’t be able to see the thin ice…..???????????????????????????????Animals have been walking on the lake for awhile and depending on when they walked, their tracks have completely different profiles. I am not sure if my theory is correct but the “prints” that are raised from the ice surface were made a few weeks ago and then they filled in with snow and/or ice. With the ensuing rain event and then freeze, these prints had different properties and formed little spires. The indented prints were from animals walking in the slush after the rain.???????????????????????????????And as you walk around, there are lots of interesting patterns to see. The little white dots are caused by something and the largest are half an inch across. Getting out on the lake is always special but you can’t always explain what you see.
