A replica of "Lupe the Mammoth". The bones of this juvenile Columbian mammoth were found along the Guadalupe River.

"This has been my first experience working with the Children's Discovery Museum, or any other museum, in developing an exhibit," says Kaitlin Maguire, graduate student at the UC Museum of Paleontology.

She's been working with the Children's Discovery Museum (CDM), for the past two years as a consultant for their upcoming exhibit, Mammoth Discovery!, that opens on Saturday, June 11th. The exhibit features a replica of the full skeleton of a juvenile Columbian mammoth, Lupe, named after the Guadalupe River where she was found.

"I was brought in to provide the content about mammoths and the history of San Jose during the Ice Age. And so my role has been providing information to the staff here so that they could create the exhibits. That includes little things like what was the vegetation like during the Pleistocene to how old Lupe was, how big [she] was. And also helping with brainstorming to fabrication."

Kaitlin also led the staff on three trips to give them an idea of how a paleontologist works in the field.Two of the excursions spanned the coast from San Francisco to Santa Cruz, where they examined invertebrate fossils, such as shells, and also vertebrate fossils, such as whales and seals and sea lions. They also traveled to Del Puerto Canyon for their third field trip, where they studied terrestrial deposits, or land deposits, that contained fish and plant material. "On each of these field trips, I showed the staff the tools that I use: hammers, picks, notebooks. I also taught them the geology of the area, so they understood the rocks that they were looking at. And I taught them about the animals that they were looking at. In addition, I showed them the proper way to collect a fossil, proper way to document it. Basically everything from start to finish."

She's learned quite a lot from her experiences of working with CDM. "It’s been an incredible experience to understand how an exhibit is built from the brainstorming phase all the way through to fabrication, and the amount of thought to detail, the amount of testing that’s required. I will never go to a museum again and not think twice about the amount of work that went behind building that exhibit. I also have a really, a great appreciation for this museum in keeping everything accurate and unique and true to the story that this mammoth provides us and really staying true to the evidence that is provided by the mammoth and creating a wonderful experience for the children."

Note: In the video, Kaitlin says Lupe is between 2-3 years old. To clarify, "She's older than 2 or 3 years old but probably not older than 10. Paleontologists are not sure of her exact age but do know that she was a juvenile."

There is something about these rocks that draws you in. Maybe it's the way they jut out of the ground? Or perhaps it's the "Stonehenge" way they form an enclosed circle? Or maybe it's just a nice place to get out of the wind? Whatever it is, they seem to pull you towards them. And once you are there, they almost call out to be touched. The rocks, long known as the "Sunset Boulders," have attracted rock climbers for years. I've climbed these rocks before. But like so many other people, I had no idea I was touching history.

During the Pleistocene, 10 to 20,000 years ago, this place was very different than it is today, inhabited by massive mega-fauna; bigger elephants, lions, bears and wolves, than we see today. While those big animals went extinct thousands of years ago, they left their mark on this place.

Looking around these rocks it is easy for me to imagine the herds of Columbian Mammoths lumbering from the nearby wallow to rub against the boulders. I can picture huge herds of camel and horse grazing nearby. Yes, those animals evolved here in North America and then crossed into Asia where they thrived and survived. Weaving my way between the boulders, I can imagine how the predators could have used these rocks as an ambush site. I envision a huge saber-tooth cat slinking between the craggy rocks, looking to pounce on an unwary bison. I can see the prides of American Lion, similar but much larger than African Lions, basking on the tabletop boulders after a big kill. I can also picture the ultimate predator making their campsite here when that first hunting party foraged deeper inland. Yes, humans were here too. And I'm sure the same pull these rocks have today existed back then.

This seems like a sacred place to me. Sacred to history. So when you visit these rocks think about those who came before you. Think about the mammoth and the bison and the camel and the horse. Think about the lions, tigers, bears and wolves. And think about those first people. Tread lightly and respect this wonderful place. With care, these rocks will be here long after we all become part of history.
