We spoke with National Geographic Traveler Magazine editor-in-chief Keith Bellows about what makes a great beach town, and he gave us some idea locations all across the country. This inspired us to make a list of New Hampshire summer spots, with particular attention to one of the state’s specialties – lakes. We’ve also squeezed a couple rivers in here as well.
On July 22nd, bulldozers breached the Veazie dam in Eddington, Maine – an 830 foot strip of concrete that had separated the Atlantic Ocean and the Penobscot River for a century. It was an effort undertaken by an unlikely coalition of conservationists, fishermen, power companies and others, who came together to help restore 1000 miles of endangered Atlantic salmon habitat. Brian Graber is director of the river restoration program at American rivers, one of the partners behind the project.
Henry David Thoreau's death 150 years ago has inspired memorial events in Concord - the Massachusetts Concord - but Thoreau passed through our Concord on a trip by boat and foot that led to his first book.
June is National Rivers Month, which means it’s a good time to talk about a recent film chronicling the effort to clean up the Nashua River. It’s called “Marion Stoddart: The Work of 1000” and has been screened at a number of environmental film festivals.
Susan Edwards is the film’s producer, and she talks with All Things Considered host Brady Carlson about, the film, Marion Stoddard and the Nashua River.
Dear EarthTalk: How is it that dams actually hurt rivers?-- Missy Davenport, Boulder, CO
Dams are a symbol of human ingenuity and engineering prowess—controlling the flow of a wild rushing river is no small feat. But in this day and age of environmental awareness, more and more people are questioning whether generating a little hydroelectric power is worth destroying riparian ecosystems from their headwaters in the mountains to their mouths at the ocean and beyond.
You learned a remarkable property of H2O back in High School chemistry. Remember?
Normally, the density of compounds decreases as temperatures increase and molecules spread out. When temperatures fall, density increases as molecules become more tightly packed. Not true for ice – in fact, the exact opposite occurs!
In liquid form, each water molecule’s hydrogen is bonded to 3 other water molecules. In ice form, each molecule’s hydrogen bonded to 4 others. These hydrogen bonds form an open arrangement that is less compact than liquid water.
