Snowmobile Ax 

Wardens say the area where the man went into the water Saturday night on South Twin Lake near Millinocket is close to the area where a Connecticut man died in early April 2008 while snowmobiling on thin ice near moving water on North Twin Lake.

Wardens say there are some spots that never freeze in Maine and outdoor enthusiasts need to check with locals before going onto ice.

Wardens say Dennis Belmonte of Middleton, Mass., was unharmed in the latest incident, but his rental sled sank in 30 feet of water.
