Rare giant ice circle appears briefly in Washington State river

This weekend, word spread via Facebook that a large circle of ice was spinning in small river just outside of Seattle. After seeing a quick video of it in her feed, photographer Kaylyn Messer jumped in her car and was fortunate to witness the incredible sight of this gargantuan ice disc as it spun in the current of the Middle Fork Snoqualmie River.

"The ice circle was pretty captivating," Messer shared with Colossal. "You can hear the sound of the river flowing continuously. Sounds from the ice periodically interjected with very small sharp cracks and groans. Overall, it was a quiet experience to stand along the river watching the ice circle rotate."

Ice circles are a fairly rare phenomenon that occur mostly in North America and Scandinavia in slow moving rivers during the winter. The discs are formed when a large piece of ice breaks off in the river creating an effect called 'rotational shear' where the current slowly grinds away at the free-floating chunk until its smoothed into a perfect circle.

Messer shares more photos and videos of the ice disc on her blog.

Whale carcass towed to Angel Island, California for necropsy

Dead whale towed to Angel Island
A dead whale that washed up near the Oakland waterfront on Saturday is now tied to a pier on Angel Island waiting for clear weather so local marine biologists can investigate the cause of death.

The female cetacean is either a blue or fin whale and is between 40 to 60 feet long, said Marine Mammal Center spokesman Giancarlo Rulli.

On Saturday, the U.S. Coast Guard called the Marine Mammal Center to report a whale carcass floating upside down near Oakland's Howard Terminal, Rulli said.

The Center sent out two staffers to examine the animal, which is believed to be "sub-adult" and in "good body condition," although quite obviously dead.

Monday morning, the U.S. Army Corps of Engineers used two boats to tow the carcass to an area near Blunt Point on Angel Island, where there is ample space to haul it onto a beach for a necropsy once weather permits.

Quake measured at a depth of 617 km, according to the US Geological Survey


A major undersea earthquake with a magnitude of 7.3 struck southeast of the Philippines on Tuesday, the US Geological Survey (USGS) said.

The quake was measured at a depth of 617 km (380 miles), the USGS said. It struck in the Celebes Sea and comes five days after a smaller, 4.7-magnitude tremor in the same area, according to the USGS.

Journalist Barnaby Lo said he felt "no significant tremor" on the island of Jolo, which lies north-east of the epicentre. The US Tsunami Warning Centre has issued no warning, advisory, watch or threat after the quake.

Philippine seismologists said the earthquake was far too deep to cause any damage and casualties or generate a tsunami.

Cirrus clouds create 22-degree sun halo in Alabama sky

Sun halo today over East Alabama...
A veil of high and mid-level clouds spreading across the Tennessee Valley Sunday was the perfect setup to see a rare sight in the sky.

Several WHNT News 19 viewers, including Ramona Edwards and Tressi Downs, shared pictures with us of a large ring around the sun.

This optical feature is called a 22-degree sun halo.

Earthsky.org explains it very simply:
Halos are a sign of high thin cirrus clouds drifting 20,000 feet or more above our heads. These clouds contain millions of tiny ice crystals. The halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals.

Up to 80 swans killed by bird flu at UK nature reserve; avian influenza found at 8 other sites in the country


Up to 80 wild swans at the Abbotsbury Swannery in Dorset have died after a bird flu outbreak
A famous swannery owned by one of the richest women in Britain has been struck by a bird flu epidemic.

Eighty wild swans have died at the historic Abbotsbury Swannery in Dorset - with nine confirmed cases of H5N8 strain of avian influenza.

The site is owned by Charlotte Townshend, the granddaughter of the 7th Earl of Ilchester and daughter of the 9th Viscount Galway.

The 61-year-old - whose fortune has been estimated at £420 million - is the only person in Britain other than the Queen entitled to own swans.

It is the same strain of avian flu that has broken out in other areas of Britain, including the Wildfowl and Wetlands Slimbridge reserve in Gloucestershire.


The case is the latest of wild birds testing positive for avian influenza this winter
