Rare Snow Rollers Form Across Idaho

Recently, two Idaho residents named Dan and Dennis Robbins stepped outside after a snowstorm. They witnessed a surreal site: dozens of icy cylinders made entirely from snow, strewn across a hill with no sign of human interference.

According to CityLab, these unusual hollow formations are called snow rollers. (They're also sometimes referred to as snow doughnuts.) They're extremely rare, and only form in very precise weather conditions. A strong wind picks up a chunk of snow on a hill, bluff, or other inclined surface and rolls it along the ground. As the snow piece moves, it picks up even more snow, growing larger and larger until it's eventually too big for the wind to push it any further. The snow on the ground has to be the right mixture of wet and loose, icy and packed, for the accumulated mass to form a perfect wheel. In other words, the perfect (snow)storm of events needs to exist for snow rollers to blow into your own backyard. 

Throughout the past few years, snow rollers have been spotted everywhere from Washington State to Parkersburg, West Virginia and Norwood, New York. Last year, they popped up across Ohio, Illinois, and Pennsylvania. If you're lucky enough to see a snow roller in your own town this winter, take a picture. After all, they don't come along every day—and they won't last long.

Washington, D.C. Residents Pay Tribute to Fallen 325-Year-Old Oak Tree

Washington, D.C. is perhaps most famous for its historic monuments and buildings, but residents of the city’s Northwest quadrant recently took time to mourn the death of a centuries-old tree, according to NPR.

The sturdy red oak in D.C.’s Shepherd Park neighborhood was 75 feet tall and its trunk was 5.5 feet wide, with sweeping branches that soared over the porch of an adjacent home. Experts believe it first took root in the late 1600s, making it around 325 years old.

Washington, D.C. wasn’t founded until 1790, so the tree predated the creation of the city. Over the centuries, it stood tall amid countless wars, presidents, and national triumphs and tragedies—but it recently fell victim to the ravages of time and gravity when a large section of its cracked trunk splintered off and fell to the ground.

Nobody was injured and property damage was minimal, but the arduous cleanup process took a six-member crew eight hours to complete, according to The Washington Post. They deployed a 100-ton crane to remove the tree—a job that cost $12,000, as two of the tree's base parts weighed 17,000 pounds and 14,000 pounds, respectively.

All that remains of the tree is its stump, which provided experts clues about its age through its rings. John Anna of Adirondack Tree Experts, the company tasked with removing the tree, told the Post that the red oak was one of the oldest trees he’d seen in his 30-year regional career. As for locals, many had enjoyed its shade for years and felt like they’d “lost a member of [the] family,” a former neighborhood resident named Ruth Jordan told the Post.

Paris to Turn Its Parks and Gardens into 24-Hour Summer Attractions

If you're visiting Paris this summer, consider packing a picnic basket. As Travel + Leisure reports, city officials will launch a two-month initiative in July to keep 16 of the metro area’s largest parks and gardens open 24 hours a day.

Called "Les Jardins Nocturnes" (the Night Gardens), the event will run from July 1 through September 3. Nature lovers can enjoy moonlit green spaces like the Parc des Buttes Chaumont—which has a Roman temple replica perched atop a cliff, overlooking a man-made lake—and the sweeping green lawns of the Parc Montsouris in the city’s 14th arrondissement.

More than 130 of Paris’s smaller parks and gardens are already open to the public during the evening. Once Les Jardins Nocturnes begins in July, nearly half of all of the city's green spaces will go 24/7. According to officials, the seasonal initiative is intended to help Parisians enjoy the city’s natural attractions after work, and take summer strolls during the cooler evening hours.

City parks aren’t always the safest places at night, which is why security teams will be deployed to keep an eye on late-night patrons. But while you're embarking on evening nature excursions, make sure to mind your manners: In 2016, Paris launched a similar parks program, and nearly 700 residents near the Parc Montsouris signed a protest petition complaining about excessive noise and litter.
