Pressure ridges are a major hazard on Moosehead Lake. With more snow on the way, there are growing concerns about one open ridge in particular.

Snowmobilers are being warned of open pressure ridges on Moosehead lake. One particularly large ridge has opened, posing a danger to snow sledders. According to a Facebook post by The Birches Resort, "the pressure ridges by Kineo (on the staked trail) has opened up. This is extremely dangerous. Exercise extreme caution." The photo above is an actual picture of this ridge, taken by Chris Davis.

At last report, the ridge was marked by Game Wardens.

Pressure ridges are caused by the shifting and expanding of lake ice. The expanding and contracting of the ice can cause it to buckle upward, or pull apart. Open water can refreeze posing as safe ice when it's actually dangerously thin. When covered in snow, it may be completely unnoticeable.

If you're new to the sport, we put together a list of gear you'll need for a fun, comfortable, and successful day on the ice. Some of these items are more essential than others. Some gear may not be essential at all, depending on how you plan to fish. Again, the items we listed are geared towards those who are new to ice fishing.
