Is it just our imagination that recent winters have started later and ended earlier or can that be verified by a simple measurement of pond ice? Well that's exactly what we've been doing at Blue Hill Observatory since 1886, watching Houghton's Pond freeze and then thaw.
During a normal winter we would expect this picturesque little kettle pond to freeze over by December 12th, but last year, and now it looks like this year, that probably won't happen. Likewise, our spring thaw of pond ice is gradually getting earlier. With a normal thaw around March 22nd, last year ice on Houghton's Pond was completely gone by February 23rd.
Would you believe, we also keep track of when the first delicious Blue Hill blueberries ripen? We've been doing that also since 1886.
So what will this winter bring? Enter our contest and give us your prediction as to when the pond will freeze/thaw and when the first ripe blueberry will be ready for picking next spring.
