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.
But as the climate grows hotter and drier, giant sequoias previously thought to be almost indestructible are increasingly threatened by 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, 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.”

Scroll down for a list of fireworks restrictions across Wyoming.
I usually don’t buy fireworks for the 4th of July. I go places to watch them. But since this year is the 250th anniversary of our nation, I was going to purchase a small arsenal and have a blast, pardon the pun.
But this has been a very dry year, as happens now and then in the cycles of weather. So I figured I’d wait until things were wet again and just hold my personal celebration a little late.
Many towns across Wyoming have canceled their July 4th fireworks due to the drought. They don’t want you firing off any either.
Based on 2026 reports, several Wyoming towns and counties have canceled or significantly restricted Fourth of July fireworks displays due to high wildfire risks, drought conditions, and Stage 1 fire restrictions.
Canceled/Restricted Public Displays (2026)
- Gillette/Campbell County: The CAM-PLEX fireworks show was postponed, and the county is maintaining a Stage 1 fire restriction due to extreme drought.
- Douglas: The Volunteer Fire Department canceled the 4th of July fireworks show due to fire concerns.
- Newcastle: Fireworks show canceled due to high fire danger, according to a June 27 report.
- Pine Haven: Canceled its Fourth of July fireworks display, according to a June 27 report.
- Riverton: Passed a resolution banning personal fireworks within city limits on July 4, with only a limited, designated area for public displays at the Honeycutt Softball and Saban Baseball Complex.
- Teton County: Fireworks have been historically canceled, and fire officials are urging residents to only attend official, professional displays due to extreme fire danger (confirmed for 2026).
City-Wide Personal Fireworks Bans (2026)
- Cheyenne: Consumer fireworks are prohibited within city limits, despite the county lifting restrictions, with only small novelties allowed.
- Casper: Fireworks are prohibited within city limits and in unincorporated Natrona County.
Key Locations Under Restrictions (2026)
- BLM Land: Fireworks are prohibited on public lands managed by the Bureau of Land Management in Wyoming.
- Weston County: A county-wide ban covers Newcastle and Upton due to high drought conditions.
Even little Chugwater, Wyoming, population 175, has banned fireworks inside its little town limits.
At the State Capital in Cheyenne, however, they will go right ahead with a fireworks display, right over the capital building itself. Dry weather be dammed.

After an extended wait of no activity from the Denver Nuggets in this year’s free agency period, the team has finally made its first new signing.
That signing just so happens to be the No. 2 pick from the 2018 NBA Draft, Marvin Bagley III.
According to ESPN‘s Shams Charania, the Nuggets and Bagley have agreed to a one-year, veteran minimum deal for the 2026-27 season, effectively providing some solid depth in the frontcourt.

With Denver’s first free agency signing now officially in the books, here’s what the move to bring in Bagley might mean for the Nuggets moving forward into free agency and this offseason, as well as entering next season.
Marvin Bagley Brings Frontcourt Depth to Denver’s Lineup
Bagley split his time between the Washington Wizards and Dallas Mavericks this past season to put together one of his better years of production in recent memory.
In the 60 combined games he played, Watson averaged 10.5 points, 6.1 rebounds, and 1.4 assists while shooting a career-high 61.8% from the field and 46.2% from three on a little less than one attempt per game.
Bagley’s a big who’s game centers more around his offensive skillset. He spent most of his time shooting last season at the rim or in the mid-range, shooting a stout 64.1% on two-pointers last season that can bring a bit of an interior presence into Denver’s frontcourt.
Defensively, he leaves a little bit more to be desired. And he’s still not quite the most impressive three-point shooter, even coming off his most efficient season from deep.
But for the cost of a veteran minimum contract, he acts as a nice budget-friendly addition who can shoulder some of the load offensively, and has shown value as an offensive rebounder as well. It’s tough to find much better for the price Denver’s paying.
While entering the league slotted in primarily as a power forward, it’s been in the past few seasons that Bagley’s settled in more as a full-time five; having spent 95% of his minutes during the 2025-26 campaign playing at the five.
That might give you a bit of a hint as to how the Nuggets plan to use him this next season, though they might also have some stretches where he’s placed alongside Nikola Jokic at the four for a bit of a larger frontcourt lineup.
The Writing’s On the Wall for Jonas Valanciunas
Looking at what Bagley’s addition might mean for the Nuggets’ current roster, no one in the picture gets more impacted by Jonas Valanciunas.
Valanciunas was Denver’s primary backup behind Jokic at the five last season following his trade from the Sacramento Kings, and entered this offseason with an uncertain future because of his contract situation.
The veteran big man has an expiring $10 million contract heading into the 2026-27 season, but one that’s not fully guaranteed, giving the Nuggets the opportunity to release him and save $8 million, while incurring a dead cap hit of $2 million that can be stretched over multiple years.
Such a move can give the Nuggets further cap flexibility that they’ll need this offseason to re-sign key pieces like Peyton Watson and Spencer Jones, which to this point haven’t been done, but becomes a bit easier now that Denver can take that next step in pivoting off of Valanciunas.
Perhaps Denver might also look deeper into a trade involving Zeke Nnaji, now that they’ve got a cheaper option in Bagley that might even sit ahead of him on the initial depth chart. However, it remains to be seen if the Nuggets have any takers on the two years remaining on his contract. To this point, they haven’t found anyone to bite.
When factoring in Valanciunas and Nnaji though, Bagley’s addition now brings the Nuggets to a total of 10 players signed onto traditional contracts for the 2026-27 season.
That leaves them with four open spots left to utilize in the days and weeks ahead. How they decide to use that space remains to be seen, but at the very least, the Nuggets’ long-awaited first offseason signing has now officially come to light.
