Recently We've been riding mostly Lake Chocorua due to the high quality surface conditions. It's one of the few lakes that has good snow on it. This of course is a blessing and a curse because as nice as it is to ride the snow has ground ice production on the lake to a halt. Fortunately the ice is variable 3-6" of black ice and not cloudy weak ice. As anyone who knows the area will tell you, Choco is probably one of the hardest lakes to ride because of the wind quality. But it's worth it once you get a feel for it. With the recent warm trend the snow on top has turned mostly to slush/snow. Nice during the day still but brutal in the morning after setting up over night.
We haven't been to Umby yet this season but they have been hauling sheds out onto the ice with 4 wheelers and it's been very cold up there. Cold enough to probably make ice under the snow cover.
We should be in the cold for a while yet. Even with temps creeping up a bit we are still making ice at night and it looks like we will get some sort of decent season in even if it's going to be a short one. Lakes that are in the same state as Chocorua will fall apart fast this season so be mindful of that as spring approaches. In the meantime remember if you head out, ask the locals what the ice is doing. Bring your rescue picks and note potential risk areas. Best bet is to wait until the snowmobiles are on the ice if you really want to err on the side of caution.
