The La Brea Tar Pits – home to more than 3.5 million Ice Age fossils – is one of the planet’s best-kept records of what it was like in the area we now know as Southern California over the last 60,000 years.
Why it matters: The La Brea Tar Pits does not just tell the story of the region’s past. Its collection of Ice Age fossils also helps scientists understand what led to the most massive extinction of megaspecies on earth since dinosaurs, when droves of large mammals suddenly died as extreme heat, drought and large-scale wildfires overwhelmed the region.
As we endure another period of significant environmental change, these fossils also offer a window into the future.

Digging Into LA’s Past, Present and Future at La Brea Tar Pits
More than 13,000 years ago, when an abundance of saber-toothed cats roamed the Los Angeles Basin, the giant mammal would hide in tall savanna grasses or behind juniper shrubs and stalk its prey.
“We think they were probably ambush predators,” says Emily Lindsey, associate curator and excavation site director at the La Brea Tar Pits museum and paleontology research site.
When it spotted its target — horses, camels, mammoths or other large animals known as megafauna — it would use its powerful forearms to leap out and pin down its prey.
Then, using its 8-inch-long curved canines — serrated like a steak knife — it would slice through a vein and let the animal bleed out.
“All of that information is based on research here because we have this incredible collection of more than 2,000 saber-toothed cats,” Lindsey says. “It’s really rare that we have the whole record. You don't usually get that in paleontology.”
L.A.'s climate past and future
The La Brea Tar Pits — home to more than 3.5 million Ice Age fossils — is one of the planet’s best-kept records of what it was like in the area we now know as Southern California over the last 60,000 years. It’s also the world’s only active urban fossil dig site.
Fossils found in the asphalt help paint the picture of the life that once flourished here during the Ice Age: saber-tooth cats, giant sloths, dire wolves, grizzly bears, bison as well as juniper and oak trees.

But it's not just telling the story of the region’s past. This collection of Ice Age fossils also helps scientists understand what led to the most massive extinction of megaspecies on Earth since dinosaurs, when droves of large mammals suddenly died as extreme heat, drought and large-scale wildfires overwhelmed the region.
We have a really unique insight on that story because we can actually look at these different windows of different habitats from different times and see how they respond to climate change in real time.
— Emily Lindsey, associate curator and excavation site director at the La Brea Tar Pits museum and paleontology research site
And as we endure another period of significant environmental change, these fossils also offer a window into the future.
“There was this ‘ah ha’ moment for paleontologists,” Lindsey says. “We said: ‘Oh wait, we have a really unique insight on that story because we can actually look at these different windows of different habitats from different times and see how they respond to climate change in real time.”
It’s part of a growing field called paleoecology, which aims to use the knowledge of prehistoric ecosystems that fossils yield to predict how plants and animals will respond to environmental events now and in the future.
“The fact that we have particular species of plants, or insects, or birds, or rodents can tell us a lot about how hot or cold it was, how wet or dry it was, and how that environment changed through time,” Lindsey says.
This link between the end of the Ice Age and the global warming we’re experiencing now is a focus of the ongoing research at the Tar Pits. Particularly, scientists seek to use fossil data to make decisions about how to preserve biodiversity today.
“You can only get that by looking at the fossil record,” Lindsey says.
The tar pits
About 1,000 feet beneath the metropolis of L.A. sits the Salt Lake Oil Field. (The Los Angeles Basin is the richest in terms of oil by unit volume on earth). That, paired with the abundance of earthquakes in the region, which create cracks and chasms in the earth, paves the way for the tar pits.
Tar pits — sticky, shallow pools of asphalt that seep up through cracks and fissures in the ground — are essentially naturally occurring preservation deposits. The asphalt is so sticky that when animals stepped into it — even enormous ones like the now extinct pre-Columbian mammoth — they got trapped and couldn't get out.

The result? Meticulously preserved fossils that have been embalmed in asphalt for tens of thousands of years without exposure to air.
“So we get phenomenal preservation not just of bones, but of leaves and wood, insects and shells,” Lindsey says. “That’s what’s allowed us to build up the richest record of Ice Age life anywhere.”

Using the fossil record to inform conservation decisions
Studies from Tar Pits researchers suggest extreme heat, drought and large-scale wildfires might be at the root of the last major extinction event.
Last year, a study published by researchers there found that large-scale wildfires — possibly started by humans — wiped out many of the large Ice Age mammals. The research broke new ground in an ongoing scientific debate over what triggered the Earth’s last major extinction event.
It adds more evidence to the growing understanding that extreme heat, drought and wildfires can drastically change habitats, leading to species extinction.
“This is just one example of how we can use fossil data to inform conservation and land management decisions today,” Lindsey says.
In an ongoing partnership with the Nature Conservancy, La Brea Tar Pits is now developing a practitioner's guide for land managers, mapping out ways to use fossil data in environmental decision making.
“In other words: How do you use historical and paleontological data to help inform conservation and restoration work in urban areas?” Lindsey says. “This will help address that.”
"When planning for these types of projects, The Nature Conservancy sets goals using information from a variety of sources," says Sophie Parker, director of science for climate and land use at The Nature Conservancy. "Knowing what was present at a site at multiple timepoints in the past, including the more distant past, is useful because it gives us a broader perspective on how to craft our goals."

The Tar Pits also dedicates a small section of the park as the “Pleistocene Garden,” which contains plants that grew at La Brea at different times in history found in the fossil record. With plans for a major re-landscaping of the park currently in the works, there is a focus to significantly expand plants in line with the paleontological science on the grounds.
“It’s a way to viscerally communicate that story but also bring back some of those plants and serve as seed banks and help support urban nature,” Lindsey says.
Sharing the climate story
Beyond the rich scientific research backed by tens of thousands of years of fossil data, Lindsey says the most important part of the work they do at this critical environmental moment is public education.
By presenting current climate research alongside Ice Age fossil data, the hope is that it will drive a deeper understanding of our environmental crisis and emphasize a dire conclusion: then, as now, climate changes and human activities can intersect to drive large scale extinctions.
Five degrees celsius — that’s the difference between half of North America being under an ice sheet and today.
— Emily Lindsey, associate curator and excavation site director at the La Brea Tar Pits museum and paleontology research site
It's all laid out for the public to see in the La Brea Tar Pits museum and across its grounds.
“To have a place in the third biggest city in North America where people can see an entire scientific process," says Lindsey, "that’s another very powerful thing.”

There is one notable, but perhaps hopeful, difference between then and now, Lindsey says.
The climate change that occurred at the end of the Ice Age 13,000 years ago was purely related to the earth’s orbital cycles.
Today, it’s 100% us.
“Meaning we completely have the ability to stop it if we want to,” Lindsey says. “It’s just a matter of political and societal will. I hope this helps people understand that small human actions could push the ecosystem to a tipping point.”

Topline:
Utility boxes are a popular canvas for public art, but a Los Angeles street artist has taken the idea further — transforming one into a miniature theater.
Why now: Since S.C. Mero installed the box theater just a few weeks ago, dozens of performers have already reached out and begun using the space, ranging from poets to musicians and clowns.
The backstory: Mero often transforms overlooked street fixtures into pieces about urban life. A previous installation at the same corner — an oversized mailbox symbolizing the elusiveness of homeownership — stood for about five years.
Walk through cities around the world and it's easy to spot the trend: utility boxes painted and transformed into public art to spiff up neighborhoods.
In downtown Los Angeles, street artist S.C. Mero has taken the idea of the utility box as art in a different direction with one she’s installed in the Arts District.
“Would you like me to open it up and you can see?” she asked on a recent morning.
At first glance, it looks like an ordinary electrical cabinet — gray, about the size of a refrigerator, with slotted vents. But instead of the usual fire-resistant metal, this one is made of wood with a faux concrete base.

Mero spins two combination locks and pulls open the door.
A hidden theater
Inside, instead of a tangle of cables and cords, red crushed velvet covers the walls from top to bottom.
A gilded clock and gold-framed pictures of two other electrical boxes (“possibly its mother, and its great-grandfather”) adorn the tiny interior, inspired by one of downtown’s oldest and grandest movie palaces, the Los Angeles Theatre.
“The first time I went into that theater, the feeling that I had, I wanted people to have a similar feeling when they opened this up,” she said.
Like the theater, the box is meant to bring audiences together. Mero invites performers to step inside, and since its installation a few weeks ago, some 30 poets, magicians, puppeteers and clowns have reached out about using the space.
Many are female artists.
“Maybe it's because of the scale of it, they feel like they can actually have a chance to get inside,” Mero said.
A tradition of unexpected art
The box theater sits on the 800 block of Traction Avenue, across the street from the historic American Hotel, an early hub for artists in the neighborhood.
Jesse Easter, the hotel’s night manager, has a front-row seat to the box theater performances.
“The Arts District is still alive,” he proclaims.
Easter first arrived in the neighborhood in the 1980s, a blues and rock musician who also professionally installed art.
He said the Arts District has long been known for unconventional public art. Famously, in 1982, artist Dustin Shuler pinned a Cessna airplane to the side of the American Hotel with a 20-foot-long nail.
“I was one of the people that was in the hotel that saw the room that the nail came down into, went through the brick wall, into the floor and stopped,” Easter recalls.
Easter says Mero’s installations boldly continue that tradition of guerrilla street art in the neighborhood.
After graduating from USC in 2011, she started to make sculptural works with overlooked street fixtures, exploring issues such as addiction and homelessness.

Before the theater box, Mero installed an oversized mailbox at the same corner, towering over passersby, symbolizing a housing market that remains out of reach for many Angelenos.
Elsewhere in the Arts District on Rose Street, she has installed a 13-foot-tall parking meter sculpture, commentary on the overwhelming nature of parking in the city.
Realizing a dream
The box theater is perhaps the piece that has invited the most participation.

Last week, Mero asked Easter and other local artists to perform there. He played a blues song he wrote more than 40 years ago when he first moved to the Arts District.
“It was sunset, and I was thinking, this kind of is the bookend,” he said.
Other participants performed spoken word poetry and played saxophone.
One performer, Mike Cuevas, discovered the theater by accident.
An Uber driver, Cuevas was waiting for his next delivery order by the box theater as it was being prepped ahead of the night’s performance.
Mero recalls him getting out of his car to look at what she was doing.
“He's like, what's going on here? This looks so cool,” Mero said. “He said as he's driving throughout the city, in between his rides, he writes poetry.”
Cuevas, who goes by the pen name Octane 543(12), left to make a delivery in East L.A., but he said “something in his heart” told him to return that evening.
After watching others perform, he stepped up to the box and read his poetry in public for the first time, a piece about Latino pride.

“Another generation will pass through,” he recited. “And they'll understand why we honor with proud delight, the continuous fight for the history of our brothers and sisters.”
Cuevas didn’t know Mero by name or anything about her work, but thanked her for giving him a venue.
“I just felt something beautiful with her art,” Cuevas said. “It's time for me to start expressing myself. She inspired me to do exactly what she's doing, but through poetry.”
He now plans to read again at an open mic in downtown L.A. next week.
An overture to look inside
Mero says the project has spoken to her personally, too. Growing up in Minnesota, she loved art as a child but later focused on playing lacrosse and hockey. At USC, she studied public relations.
“Once I started getting so into art, everyone was kind of shocked,” Mero said. “That's why I really want to encourage people to go inside themselves and see what's there, because you never know.”
Mero is hoping for a long run for the box theater. Its predecessor, the supersize mailbox, stayed up for five years, only toppled, she heard, after skateboarders accidentally ran into it.
In the meantime, the small theater sits unassumingly on the sidewalk waiting for its next performer, its exterior starting to collect graffiti like any other utility box.

A total lunar eclipse is happening this Tuesday. That's when the earth will move directly between the sun and moon, casting a “blood” red color onto the moon.
What: It's going to be the first lunar eclipse of the year. The process is slated to start around midnight and last until dawn on Tuesday. It’s called the “Blood Moon” because of the red hue the earth’s atmosphere refracts onto the lunar surface as light from the sun passes through it.
When: Although the eclipse begins around midnight, it won’t reach totality until 3:04 a.m., at which point it will be visible to the naked eye for about an hour. All of Southern California should be able to see it.
How else can I watch: The Griffith Observatory will be hosting a live virtual broadcast of the celestial event from midnight to dawn.
What's next: This isn’t the only lunar eclipse happening this year, but it is the only “total eclipse,” according to NASA. Another one is set to occur in August, but it will only be partially visible in North America. A solar eclipse will occur Aug. 12.

With warm — relative to Alaska — spring waters, migratory rest-stops and great feeding grounds, Los Angeles County’s coast is considered part of the “Blue Highway,” a crucial whale migration corridor and one of the best places to spot the gentle giants.
What might you see? Cetacean species you may spot in our waters include humpback whales, orcas, blue whales and dolphins. Your best chance, however, is spotting a gray whale. As school-bus-sized gray whales migrate back and forth between Alaska and Baja, they consistently hug LA’s coastline.
Read on ... for tips on where and how to spot whales near you.
It’s whale watching season, which always makes me think of the novel Moby-Dick.
In the book, Captain Ahab chased a whale for vengeance. I recently chased whales off the coast of Los Angeles, but in my case, it was in pursuit of the beauty and majesty of the natural world.
With warm — relative to Alaska — spring waters, migratory rest-stops and great feeding grounds, Los Angeles County’s coast is considered part of the “Blue Highway,” a crucial whale migration corridor and one of the best places to spot the gentle giants.
According to Cabrillo Marine Aquarium program director Jim DiPompei, many whales can be seen right in our backyard.
“There’s a little over 90 species of cetaceans (marine mammals) in the world, and we see about 30% of the species we could possibly see here in Southern California,” DiPompei told The LA Local.
Cetacean species you may spot in our waters include humpback whales, orcas, blue whales and dolphins. Your best chance, however, is spotting a gray whale. As school bus-sized gray whales migrate back and forth between Alaska and Baja, they consistently hug LA’s coastline.
But where should you go to actually get a good look at whales? Don’t worry — I got you. Here’s The LA Local guide to cruising the Blue Highway.
Top spots to watch whales from shore
Point Vicente Interpretive Center 31501 Palos Verdes Drive West, Rancho Palos Verdes Free, laid-back, on the mountains!
At the Point Vicente Interpretive Center in Rancho Palos Verdes, you’ll find an overlook dedicated to whale watching. While this is a great free spot for amateurs to come and look out for whales, this is no playground. Professionals conduct the annual whale census here, tracking the migration of whales.
This is a great place to bring a picnic basket and some binoculars to relax while scanning the ocean. Even if you don’t spot any whale action, you can visit the free natural history museum inside, which focuses on the region and its most famous inhabitants: whales. Afterward, step outside and chat with a museum docent accompanying the census watch.
If you want to see whales, stick to the coastal canyons. Canyons aren’t just massive structures above water — they are also mountains beneath the surface, offering depth, cold water and nutrients that attract food for whales. Gray whales tend to follow the canyons to stay away from the dangerous orcas.
Whale spotting 101
Whale watching season typically runs from December through May. It peaks from January to March.
When looking for a whale, try to spot their water mist blowing above the water. Gray whales typically surface for air every five minutes. When they do, they’ll blow out a water mist — that’s your chance to spot and track them until they surface again.
Get on a boat!
If you want to get eye-to-eye and really feel a cetacean’s scale, there are plenty of whale-watching cruises. They typically depart from Marina Del Rey, Redondo Beach, Long Beach, San Pedro, Dana Point and almost anywhere with a port.
Many cruises have a naturalist on board to answer questions and provide expert context to ocean wildlife.
On my tour departing from Long Beach, we saw five gray whales and a swarm of common dolphins feeding.
But be warned: If you get seasick easily, this trip might not be for you. On our two-and-half-hour trip, the boat rocked emphatically as we approached feeding sites. It’s fun if you can imagine yourself on a see-saw, but it might not be that enjoyable if that sounds nauseating.
While boat captains are not allowed to approach the whales too closely due to environmental protections, the whales can approach the boat if they choose. Sometimes the whales seem curious and watch us in return — it’s up to them and how they are feeling.
Get involved
Cabrillo Marine Aquarium 3720 Stephen M. White Drive, San Pedro
If you really catch the whale-watching bug, you’re in luck.
At the Cabrillo Marine Aquarium, they offer a whale-watching naturalist program where you can volunteer and train to be a naturalist on board whale-watching cruises.
DiPompei said they train anyone over the age of 18 “who’s interested in learning about whales and volunteering their time to be on these whale-watching boats to talk to the general public and to talk to students.”
This program was started in the 1970s by John Olge, one of the founders of Cabrillo Marine Aquarium, with an emphasis on education and showing schoolchildren the beauty of our natural world.
The aquarium is also a great place to introduce whales to children. With kid-sized exhibits and educational programs throughout the year, it’s an ideal way to show young ones just how big and beautiful our oceans are.
