For first time, researchers scale General Sherman, world's largest tree, in search of new threat to sequoias
  • Researchers climbed General Sherman, the world’s largest tree, for the first time ever and gave it a clean bill of health.
  • The researchers were looking for bark beetles, which have become more dangerous to giant sequoia trees in combination with extreme heat, drought and wildfires.
  • In 2020 and 2021, record-setting wildfires killed as much as 20 percent of the world’s 75,000 mature sequoias.

High in the evergreen canopy of General Sherman, the world’s largest tree, researchers searched for evidence of an emerging threat to giant sequoias: bark beetles.

The climbers descended the towering 2,200-year-old tree with good news on Tuesday.

“The General Sherman tree is doing fine right now,” said Anthony Ambrose, executive director of the Ancient Forest Society, who led the expedition. “It seems to be a very healthy tree that’s able to fend off any beetle attack.”

It was the first time climbers had scaled the iconic 275-foot sequoia tree, which draws tourists from around the world to Sequoia National Park.

Giant sequoias, the Earth’s largest living things, have survived for thousands of years in California’s western Sierra Nevada range, the only place where the species is native.

In 2020 and 2021, record-setting wildfires killed as much as 20 percent of the world’s 75,000 mature sequoias, according to park officials.

“The most significant threat to giant sequoias is climate-driven wildfires,” said Ben Blom, director of stewardship and restoration at Save the Redwoods League. “But we certainly don’t want to be caught by surprise by a new threat, which is why we’re studying these beetles now.”

But researchers are growing more worried about bark beetles, which didn’t pose a serious threat in the past.

The beetles are native to California and have co-existed with sequoias for thousands of years. But only recently have they been able to kill the trees. Scientists say they recently discovered about 40 sequoia trees that have died from beetle infestations, mostly within the national parks.

“We’re documenting some trees that are actually dying from kind of a combination of drought and fire that have weakened them to a point where they’re not able to defend themselves from the beetle attack,” Ambrose said.

The beetles attack the trees from the canopy, boring into branches and working their way down the trunk. If left unchecked, the tiny beetles can kill a tree within six months.

That’s why park officials allowed Ambrose and his colleagues to climb General Sherman. They conducted the tree health inspection as journalists and visitors watched them pull themselves up ropes dangling from the canopy. They examined the branches and trunk, looking for the tiny holes that indicate beetle activity.

But it’s not possible to climb every sequoia tree to directly inspect the canopy in person. That’s why they’re also testing whether drones equipped with sensors and aided by satellite imagery can be used to monitor and detect beetle infestations on a larger scale within the forests.

Tuesday’s health inspection of General Sherman was organized by the Giant Sequoia Lands Coalition, a group of government agencies, Native tribes and environmental groups. They hope to establish a health monitoring program for the towering trees.

If they discover beetle infestations, officials say, they could try to combat the attacks by spraying water, removing branches or using chemical treatments.

Bark beetles have ravaged pine and fir forests throughout the Western United States in recent years, but they previously didn’t pose a threat to giant sequoias, which can live 3,000 years.

“They have really withstood insect attacks for a lot of years. So why now? Why are we seeing this change?” said Clay Jordan, superintendent for Sequoia and Kings Canyon National Parks. “There’s a lot that we need to learn in order to ensure good stewardship of these trees for a long time.”

Alaska is celebrating America’s 250th in the fast lane… off a cliff



Alaska celebrates the Fourth of July with a unique tradition by launching cars off a 300-foot cliff.

For a moment, everything goes quiet as hundreds of eyes fixate on a patriotic, painted car perched at the edge of a 300-foot cliff. An American flag waves in the crisp Alaskan air as spectators wait in anticipation to witness one of the nation’s most unusual Fourth of July spectacles.

Within seconds, cheers echo across the mountain valley as a vehicle soars through the sky before plummeting down below. All in the name of celebrating freedom.

In Glacier View, Alaska, about two hours north of Anchorage, celebrating America’s Independence Day makes fireworks a thing of the past. Since 2005, visitors have gathered from across the country to witness The Glacier View Fourth of July Car Launch.

Volvo and a moose

The tradition began after founder Arnie Hrncir’s wife hit a moose with her Volvo in 2003. After years of not knowing what to do with the damaged vehicle, they decided, why not just throw it off a cliff?

There it all started, a Fourth of July event that has evolved from a small community coming together to witness the Volvos plummet into one of Alaska’s most distinctive Independence Day traditions.

Hrncir said the event is a great way to celebrate freedom, especially with “that beautiful red, white and blue flag waving up there in the majestic skies of Alaska.” One could assume the best part of the event is watching the vehicles soar, but it’s really the race up the cliff to collect car scraps to take home as a souvenir.

Attendees walk away each year with car stereos, rear-view mirrors, and side doors to cherish the unforgettable day.

Hrncir expects this year’s crowd to surpass previous years with a U.S. Coast Guard flyover, brisket, and many ready to commemorate America’s 250th anniversary.

Fireworks may be the traditional way to celebrate America’s birthday, but in Alaska, 250 years call for something with a little more horsepower and significantly fewer surviving vehicles.
