The “Look at the Bones!” Bit

(Some of the Arboleda Fossils housed at UC Merced!)

Summer greetings!

As a Los Angeles area resident for more than 30 years now, I’ve seen lots of changes here in that time! 

But of all the vibrant SoCal neighborhoods I’ve lived and played in, each with a character all its own, there’s one I hadn’t gotten around to visiting – even though I’ve always been intrigued by how times changed there. It’s a spot in the midst of the fancy Hancock Park district on what’s known as the Miracle Mile, and it offers a window back not only into LA’s history – but into its prehistory too.

That would be the La Brea Tar Pits! And what finally got me over to see them? Well, it was some highway decor a couple hundred miles to the north.

Okay, so I was heading up California’s Highway 99 to visit family when I drove beneath an overpass with artwork on it that looked like a herd of migrating elephants. Studying the next pass more carefully (as well as the traffic, of course), I realized by the enormous tusks on some that these must be depictions of mammoths! 

The thing is I was going through Merced at the time – a city I’d always known as “The Gateway to Yosemite”.  So why would there be pachyderm paintings on display there? 

Turns out it’s because mammoth fossils – along with over 1,000 bones from other ancient animals – were discovered in 2012 during road construction just south of Merced! And solely because of those overpasses (well played, Caltrans – well played), I exited to check out a few Arboleda Fossils on display at UC Merced’s Kolligian Library!

(I should’ve done something for perspective but trust me, these bones are large!)

Seriously, in the morning these days, my creaky bones feel annoyingly old – but they have absolutely nothing on this collection! The Arboleda Fossils (named for the freeway project which unearthed them) come from the latter part of the Pleistocene Epoch – the era of Earth’s last big Ice Age. I consulted half a dozen sources for the proper time frame and, while I couldn’t quite get a consensus (in fairness, it’s not like these people were there), it seems like this era was roughly between 2 1/2 million and 11,700 years ago.

This was long after the age of the dinosaur, so many of the “megafauna” bones found were larger versions of familiar animals like camels, bison, wolves, horses, and the big ticket item – mammoths. Even an oversized sloth somehow slow walked its way from then into the present! Humans were around during this era too, and their hunting may have been responsible for the extinction of some of this big, big game.

The fossil collection is technically owned by Caltrans, and more of it is on indefinite loan to view at the Merced County Library. Plus, if that’s not enough, there are even more bones and activities for kids at the Fossil Discovery Center in nearby Chowchilla.

(Land around UC Merced campus!)

Looking out across the fields from UC Merced, I could pretty easily imagine this array of ancient wildlife roaming around. But I had a bit more trouble conjuring the same scene in LA:

(View from LA County Museum of Art!)

I’ve been aware of the La Brea Tar Pits & Museum since before I even lived in the area. They’re part of a fantastically eclectic concentration of museums along a few blocks of Wilshire Blvd., including the Los Angeles County Museum of Art (LACMA), the Petersen Automotive Museum and the Academy Museum of Motion Pictures! (Fossils, Fine Art, Ferraris, and Film – how could you go wrong?!)

But it was seeing those bones in Merced that was the final push I needed to dive into the tar pits at home! (Annnd that would be a figurative dive.) Just in time too as the museum closes on July 7th for a two year renovation project. (Sorry – nothing like plugging something that won’t be open for a while…) Two years, though, isn’t even the quickest wink of an eye compared to the length of time that creatures were unknowingly giving their lives for paleontology right here!

(You can just see a kid fulfilling the time-honored pastime of rolling on the grass!)

There’s a fee for the George C. Page Museum, but the grounds are free to wander – as well as to uphold a local tradition of rolling down its grassy hill! A really good way to shed the vibe of modern high-rises and manicured lawns is to gaze across the Lake Pit. It’s left over from the 1800’s when some Californians didn’t get the memo about gold, but were mining for asphalt instead!

Providing a hint of the oil field deep beneath, it’s actually asphalt rather than tar that’s been the sticky substance trapping animals from mammoths down to bugs (along with one ancient human) for thousands of years and leaving behind a treasure trove of bones. Bubbles that still gloop up to the surface of this little lake are caused mostly by methane gas, with hydrogen sulfide’s contributing a distinct – and not entirely pleasant – odor.

(The Lake Pit!)

The fossils indicate that this natural version of fly paper was complicating animal life at this Hollywood-adjacent site throughout a period from about 11,000 to 50,000 years ago. One animal might get stuck in the ooze which would attract others that then tried to feed on it – only to meet the same sort of Pit of Sarlacc-ish fate too. 

And I thought showbiz was rough…

(No, these guys aren’t real – thankfully…)

Excavations of the area began in the 1900’s and, as can be observed while strolling the park, they continue today and still produce finds!

(Pretty sure this is Pit 91!)
(Finds in Pit 91!)

And then there’s the museum itself which serves up lots more prehistoric detail, plus incredible examples of the more than a million bones that have been discovered! I started my tour with a 3-D movie called “Titans of the Ice Age”, which was as thrillingly close as I care to come to meeting a mammoth. And while wandering the displays, visitors have the chance to observe volunteers and scientists in the Fossil Lab as they clean and conserve found fossils:

(Bear skeletons with the Fossil Lab behind!)
(Annnd one of the big guys!)

The top type of animal found here was the dire wolf – about 4,000 of them came and, like visitors to Hotel California, could never leave. Second place went to more than 2,000 saber-toothed cats; and coyotes came in third.

(Just a few of the dire wolf skulls unearthed!)

Now that I’ve broken the Ice Age ice for myself, I now know there’s much more cool stuff to see! Like I’ll try not to wait 30 years to get a look at the fossils housed at LA County’s Natural History Museum. Since LA was under water back in dinosaur days, that era is represented by an exhibit of nearly 40 creatures that swam the seas. And at Fossil Ridge Park in Sherman Oaks, it’d be fun to get a look at fossilized sea life left “in situ” among the rocky slabs.

I love that there’s so much evidence of ancient life for people yet to discover here in the Southland – and all over out there! I sure love too that delightful discoveries for myself can lie just a freeway overpass away!

As we enjoy the summer, I wish for you all sorts of exciting discoveries too! Also, forgive me but I can’t help mentioning that it’s important to keep our eyes on the road – and do keep an eye out for mammoths as well!

Cheers!

    I cannot imagine the La Brea Tar Pits being in America. The old world yes. The new world no,

    How interesting! And fascinating.

    The tar pits were an obligatory school field trip when I was growing up in LA back in the day. I still remember their distinctive smell (not bad, just distinctive). It says something that there are way more predator bones in the pits than those of their prey. I guess one giant mastodon meal was too big to miss. And I had no idea fossils had been found up in the Central Valley! The Valley was probably teeming with large critters before humans arrived for lunch…

    Fascinating place, the museum and tar pits. Good for you that you were looking up and saw mammoths on the underpass, otherwise you might have missed this place
