In addition to Lloyd’s Sliver of Chickawaukee, Lake Wassookeag in Dexter has this to offer: www.lakewassookeag.com

And Lee Spiller describes a romantic moonlight skate on Cochnewagon Pond, about the size of Chickawaukee, in Monmouth, Me:

I got to Monmouth about 8 and checked Cochnewagon Pond right in town. Oh my gosh marvelous interconnected multi acre black ice sections (3″) with pebbly grey ice and some snow in between. Karin Wilson came down and we skated for a long time..lovely black ice and moonlight..making ice sounds. Unless something better pops up we are going there tomorrow. Probably set up an iceboat or two and maybe kitewing.
I can only think there are more places like this…I don’t know why this pond has so much good black ice but it does…and I don’t know what it looks like in daylight. I haven’t been around here to check other ponds but Karin says this is the best locally.

There’s probably still more that we’re missing, but thanks to Lee and Denis for spotting these!
