The grand teton second tower collapse grabbed attention in July 2025. This event shook the skyline of Grand Teton National Park. Rocks fell from the Second Tower on the Grand Teton mountain. It happened over the Fourth of July weekend. Climbers and hikers heard loud booms. Rangers warned people to stay away. This collapse follows a bigger one in 2022. Nature changes mountains all the time. Water and weather play big roles. Experts say it’s normal but risky. Visitors need to know why it happens and how to stay safe.
Background on Grand Teton National Park
Grand Teton National Park sits in Wyoming. It covers over 310,000 acres. The park draws millions each year. In 2024, more than 3.4 million people visited. They come for hiking, climbing, and wildlife. The Teton Range forms the park’s heart. These mountains rise sharp from the valley. The Grand Teton peak stands at 13,775 feet. It ranks as the highest in the range. The park started in 1929. It protects lakes, forests, and peaks. Moose, bears, and elk live here. Rivers like the Snake flow through. People love the views. But the rocks can shift. This makes the area exciting yet dangerous.
The Tetons formed long ago. About 10 million years back, the Teton Fault moved. It pushed the mountains up. Earthquakes still happen. The U.S. Geological Survey notes quakes up to 7.5 magnitude. Rocks here are old. Some date to 2.4 billion years. They started as seafloor mud and lava. Heat and pressure changed them into gneiss and granite. Granite makes up many peaks, including the Grand Teton. Cracks run through these rocks. They come from ancient times. As mountains rose, pressure eased. Rocks cracked more. Glaciers carved the shapes during ice ages. The last ice age ended 15,000 years ago. Now, weather wears them down.
What Is the Second Tower?
The Second Tower perches on the Grand Teton’s east ridge. It forms part of the mountain’s profile. Climbers know it well. Routes like the East Ridge pass near it. The tower looks like a spire. It stands out against the sky. Before collapses, it drew photos and stories. Now, it changes fast. Rangers call it a “repeat offender.” Parts have fallen twice in three years. This tower sits high, around 12,000 feet. Loose rocks cover its sides. Water seeps in cracks. Freezing expands them. Over time, pieces break off. The tower’s name comes from its spot. It’s the second big feature on the ridge. First Tower lies below. Climbers use these as landmarks.
Photos show the tower’s shape. Before 2022, it had a broad top. Now, it’s a sharp fang. The 2025 fall took a big chunk. Dust clouds rose. Sounds echoed miles away. A river guide saw the 2022 event from seven miles out. It looked like a spectacle. The tower’s rock is granite. It’s hard but not forever. Erosion hits all mountains. The Appalachians once towered like the Himalayas. Now, they are hills. The Tetons will follow suit. But it takes millions of years.
The 2025 Grand Teton Second Tower Collapse
Rangers spotted the fall on July 5, 2025. It happened during the holiday weekend. Warm days and cool nights stressed the rocks. A large section tumbled down. It triggered more falls for 48 hours. No one got hurt. But climbers stayed clear. The Jenny Lake Rangers posted warnings. They said, “Stay away from it.” The collapse left a pointed remnant. Photos from Instagram show the change. Dust covered the slopes below. Boulders crossed winter routes. This event links to the park’s active geology.
Experts rushed to check. Geologist John Willott spoke out. He leads Geologists of Jackson Hole. Willott said water drives the change. “Water is the most powerful force in nature,” he noted. Freezing at night pushes cracks wider. Thawing lets more water in. Cycles repeat. Hot summers add stress. Temps hit the 80s that weekend. Rocks expand and contract. This weakens them. Gravity pulls pieces down. The fall exposed new rocks. They will crack too. Willott predicts steady rockfalls. “The Tetons can loosen,” he warned. Climbers must watch out. What seems solid can shift.
Park officials closed areas. They checked trails. No major paths blocked. But high routes changed. The East Ridge climb got riskier. Rangers use drones for surveys. They spot loose spots. Visitors reported rumbles. One hiker heard booms from afar. The event made news fast. Local sites like Buckrail covered it first. They shared photos and tips. This quick info helps safety.
Previous Collapses in the Tetons
The grand teton second tower collapse isn’t new. In September 2022, a huge part fell. It was bigger than 2025’s. Tons of rock crashed down. The East Ridge took hits. Dust filled the air. Climbers called it massive. Rangers closed the Grand Teton summit for weeks. They cleared debris. No injuries then either. But it changed the skyline. The tower lost its top. It became slimmer. Photos before and after show the shift.
Other falls happen too. In 2023, smaller rocks tumbled. Wyofile reported a river guide’s view. He saw dust from miles away. The Tetons see many events. USGS tracks them. Fault movement adds risks. Quakes loosen rocks. A 1959 quake caused a landslide. It killed 28 people at Yellowstone. Tetons stay young. They rise faster than erode. But weather speeds wear. Ice ages left sharp peaks. Now, they soften.
Comparisons help understand. The Matterhorn in Europe sees falls. Heat waves melt permafrost. Rocks slip. In Yosemite, El Capitan had a 2017 fall. It killed one. Parks warn of risks. Grand Teton logs events. Over 100 rockfalls yearly. Most small. Big ones like Second Tower stand out.
Scientific Explanations for Rock Collapses
Scientists explain why rocks fall. Water enters cracks. It freezes at night. Ice expands by 9 percent. This pushes rocks apart. Cycles happen daily. Over years, cracks grow. Rocks fail. Geologists call it freeze-thaw weathering. In Tetons, nights cool fast. Days heat up. Thermal stress adds cracks. Granite resists but has joints. Ancient faults weaken it.
John Willott details this. “Everything is subject to erosion,” he says. Rocks seek lower spots. Gravity helps. Exposed faces weather more. The Second Tower faces east. Winds hit hard. Rain soaks it. Climate change speeds things. Warmer temps mean more thaw. Less snow cover. Rocks heat faster. Willott notes, “We’ve been getting hotter. That stresses everything.” Studies back this. USGS says warmer winters boost cycles. Permafrost melts in high spots. This loosens holds.
Rock types matter. Granite cracks in blocks. Gneiss layers peel. Tetons mix both. Faults run deep. Movement widens joints. Earthquakes shake loose parts. A 2024 quake measured 4.2. It rattled the range. No big falls then. But it adds up. Experts use models. They predict weak spots. Drones map changes. Satellites track shifts. This science saves lives.
Climate Change and Its Role in Teton Erosion
Climate warms the Tetons. Temps rise 2 degrees since 1950. Summers get hotter. Winters shorter. This affects rocks. More rain than snow. Water flows in cracks. Freezes less but thaws more. Cycles increase. Glaciers shrink. They once held rocks. Now, exposed areas erode. A study in Nature says mountains change faster with heat.
Willott links it. “Hotter and hotter,” he warns. Wildlife feels it too. Trees stress. Rocks crack. The Tetons erode over time. But speed picks up. Appalachians took 350 million years to flatten. Tetons might take less now. Parks adapt. They monitor weather. Rangers issue alerts. Visitors learn signs. Loose pebbles mean risk. Booms signal falls.
Global examples show this. Alps see more falls. A 2023 Swiss event killed climbers. Heat melted ice bonds. Tetons face similar. But parks prepare. Education helps. Signs explain geology. Apps track weather.
Safety Tips for Climbers and Hikers
Stay safe in Tetons. Rockfalls happen anytime. Follow these steps:
- Check reports: Read ranger updates. Jenny Lake posts on Instagram.
- Wear helmets: Protect from falling stones.
- Avoid loose areas: Stay off Second Tower routes.
- Listen for sounds: Rumbles mean danger. Move away.
- Climb with guides: Experts know risks.
- Watch weather: Hot days increase falls.
Rangers stress caution. “Just stay away,” they say for Second Tower. Park has rules. Permits for climbs. Training classes teach. Over 5,000 climbers summit yearly. Most safe. But know limits. For hikers, stick to trails. Avoid cliffs. Binoculars spot changes from afar.
If you see a fall, report it. Call rangers. This helps others. Apps like AllTrails note hazards. Groups like American Alpine Club share tips. Safety first keeps fun.
Comparisons to Structural Collapses
Nature’s falls mirror man-made ones. The grand teton second tower collapse shows progressive failure. Rocks weaken bit by bit. Then, big chunks go. Like the World Trade Center in 2001. Planes hit towers. Damage spread. Fires weakened steel. Columns buckled. Towers fell in sequence. NIST reports detail this. Impacts cut columns. Fires sagged floors. Pull-in caused collapse.
In Tetons, water weakens joints. Freeze expands. Gravity pulls. It’s slow but similar. Engineers study both. AISC notes load shift in buildings. In rocks, weight shifts too. Cracks grow. Failure cascades. Wikipedia explains WTC sequence. South Tower fell first. Asymmetric hit. Second Tower’s east face exposed more. This sped erosion.
Lessons cross over. Buildings now resist fire better. Parks monitor rocks. Drones like models. Both teach resilience. Nature rebuilds slow. Humans design strong.
