Hardy Pond singing
December 15, 2018
It’s rare, but not too rare, to hear a pond singing when it is frozen and temperatures are rising or falling. On Thursday December 13th, 2018, Hardy Pond with a solid but somewhat thin surface of ice (not safe for skating) was singing in full glory.
The following sound was captured so you can listen if you have never heard a pond singing before.

The Natural History of the Cornelia Warren Estate: Camp Cedar Hill, Girl Scouts of Eastern North America by Lesley Sneddon Now Available! Camp Cedar Hill is a portion of the former estate of Cornelia Warren . In keeping with her desire to maintain the land for public benefit, Ms. Warren wished to carry this tradition beyond her life by stating so in her will. After her death, the Trustees of Cedar Hill deeded five parcels of the estate among several beneficiaries, including the Massachusetts Girl Scouts (now the Girl Scouts of Eastern Massachusetts). To this day, Cornelia Warren’s legacy of philanthropy and social welfare continue to benefit the residents of Waltham and beyond.

A total of 54 hardy environmentalists and two dogs braved the cold winds and icy conditions to carefully hike in Prospect Hill Park to the vista at Little Prospect. 22 left from Craft Food Hall for a longer, more gradual walk through the woods while 32 departed from the South Gate for a shorter but steeper trek. At the top we enjoyed cookies and stunning views of Waltham below and the Boston skyline in the distance. Be sure to join us next year, hopefully in better conditions!
