Legend of the Peg Elves: Boy Scout Overnights offer a glimpse into museum folklore

The lights in the Morian Hall of Paleontology brighten and illuminate the Tyrannosaurus rex. The immersive soundscape in The Farish Hall of Texas Wildlife comes to life. The periodic table powers on in the Welch Hall of Chemistry. And the peg elves emerge.

That’s right. As the museum gears up for another day of exploring, learning, and excitement, the peg elves at the Houston Museum of Natural Science begin to stir. They have an important job to do. They are the protectors of the pegs.

The Foucault Pendulum is an icon at HMNS, just outside the Wiess Energy Hall. If you’ve ever found yourself walking through the exhibit halls and suddenly heard an uproar of cheering, then you know it happened; the pendulum has finally knocked over one of the wooden pegs. This happens once every 12 to 13 minutes and has captivated museum audiences for decades with its ability to demonstrate the Earth’s rotation. You can hear the disappointment when visitors feel certain the pendulum is going to knock down a peg, but it swings ever so slightly by it. It’s something I remember watching intently as a child. You root for the pendulum to mark the passage of time by knocking down one of those innocent pegs. It’s the spectator sport of HMNS.

The kids who spend the night at the museum often ask us a lot of questions about the inner workings of the museum. Frequently, they want to know “How do you get those dinosaurs in here?”, “Does everything come to life at night?” and “Who sets all the pegs back up?” That’s when we tell them about the magical yet elusive HMNS peg elves.

Scotland has the Loch Ness Monster. The Himalayas have the Yeti. HMNS has peg elves. The peg elves are bearded creatures who inhabit the innermost workings of the museum. They wait in the depths of the museum for the pendulum to swing back and forth knocking each peg down. The sound of the peg clattering on the tile is music to their ears. It calls to them. It’s their mission and purpose to set those pegs back up.

This composite sketch was created using eyewitness reports of the peg elves over the years. Reports identify the elves as typically wearing Santa hats and sunglasses, having pointy ears and beards, and reaching heights no taller than six inches.

Early in the morning before the first visitor enters the museum, the peg elves get to work. They move quickly and scamper over the walls surrounding the pegs. They place each peg with precision. The young elves observe with watchful eyes as the elders re-position the pegs. The physics of peg positioning is an art, so it’s only after a dutiful mentoring period that the younger elves are permitted to assist with the pegs. Young elves dream of the day they’re able to prop a peg up on their own. It’s a rite of passage in peg elf society.

After all the pegs are in place, the peg elves return quickly and quietly to their museum hideouts. They wait in the wings to hear that collective cheer as the pendulum swings. The peg elves know that it means there will be more work for them in the morning. After all, they are the guardians of the pendulum, the protectors of the pegs.

What’s the perfect B-Day? Puppies, reading and the museum!

For her eighth birthday, Maddie Sanders told her mom she wanted nothing more than to read to dogs at the museum. It seems like an unlikely service, but the Houston Museum of Natural Science at Sugar Land is the perfect fit for such a childhood wish.

Through the P.A.W.S. (Pets Are Wonderful Support) Reading Program, Maddie made two new canine friends, a German Shepherd named Jasmine, and Ranger, a Golden Retriever. From 10 a.m. to noon, she sat with the dogs and read to them along with her five-year-old sister Nola and her mother and father, Hope and Brian.


Maddie and Nola Sanders read to Ranger with the help of a volunteer at HMNS-SL.

“Ranger let the kids climb all over him. He was just a big pillow,” Hope said. “They were very well-trained, well-behaved dogs. As much as my kids love dogs, they were a little frightened at first. We don’t have one of our own. I have an allergy. But once they got acclimated to the situation, and they realized the dogs were well-trained and mild-mannered, the girls warmed up quickly.”

Hope learned about the P.A.W.S. Reading Program in the summer of 2014 when she was searching for activities for a Girl Scouts group field trip. She found information about the program on the HMNS-SL web site, but the logistics didn’t work out for the whole group. This time around, though, the program was great for two girls on a birthday adventure. She called up the museum to see if she could negotiate a birthday package, and Program Manager Kavita Self was happy to oblige.


Maddie read to Jasmine until she fell asleep for a mid-morning nap.

“Kavita is a joy to be around,” Hope said. “She loves her job. She told me to give her a heads-up before we got there so they’d be ready for us.”

The Sanders family hadn’t been to the Sugar Land museum in “quite some time,” Hope said, and when they got there, the expansion of the collection in the past couple of years astounded her.

“We were completely taken aback by how much it has to offer and how much it has grown,” Hope said. “They greeted us and gave us a welcome gift. We thought that was so kind. They showed us the new exhibits. Maddie is a lover of treehouses, so we played around there. They went above and beyond to make us feel special.”


Nola, Maddie’s sister, enjoyed her time in the TreeHouses exhibit at HMNS-SL.

The family saw geodes in the earth science exhibit and popped outside to watch butterflies in the butterfly garden. The only feature they missed out on was the paleontology exhibit, but there was plenty of entertainment for the whole family, let alone a single girl.

“I had no idea it was going to be anything greater than reading with dogs,” Hope said. “The people there knew her and kept telling her happy birthday. She loved the dogs so much. We had such a lovely time, and it all happened because the people there made it happen. We’re very appreciative.”

When they left the museum, the family stopped by Bernie’s Burger Bus in Bellaire for lunch, where they told everyone about their experience, Hope said.

Geology Rocks! How I got involved with Occidental Petroleum

by Tania Campbell


Here I am hiking the world famous Permian Reef Trail at the Guadalupe Mountains National Park to study carbonate rock outcrops.

I’ve worked as a production geologist for 11 years for Occidental Petroleum, and while that is a long run with one company in the energy industry, it has gone by fast. I remember being introduced to rocks in middle school, but by the time I was in high school, I was more interested in marine biology. I then went on to successfully complete a dual bachelor’s degree in marine science and geology, which laid the foundation for understanding carbonate rocks and basic geologic principles, starting me down my path as a production geologist.


The Miami Circle, where American Indians carved a circular structural support out of bedrock limestone.

The first community project I got involved in that I attribute as a catalyst to my geology interest was working with an archaeological site called the Miami Circle. Approximately 2,000 years ago, American Indians used the bedrock limestone to carve out a perfect circle to support a structure. As a volunteer I only found a few animal artifacts, but I was most interested in the exposed limestone.


A sample of core that has been cut and slabbed after it was taken from the subsurface in a well. A geologist will describe the rock types and features observed, and other interpretative data is combined to make geologic models and maps.

There are so many different kinds of specialties in geology that sometimes it can feel overwhelming trying to figure out what you want to do. I kept an open mind and set off to learn more with a master’s degree at a different school. It is highly recommended that geologists have their master’s if they want to work in the petroleum industry. I studied hydrogeology and petroleum geology for my master’s, which has helped me work better with team members from engineering backgrounds and develop further in my core profession of doing reservoir characterization. My role involves describing and modeling the layers of rock in the subsurface to predict the most favorable areas for continued secondary and tertiary hydrocarbon recovery.


Hiking with other geologists through the canyon cuts to map the rock types and observe vertical stacking of the layers of carbonates and siliciclastics.

I am extremely thankful for my education and the career opportunities that have brought me to a place where I enjoy coming to work. Every day there is a different problem to tackle. Sometimes it requires communicating with engineers and understanding other types of non-geo data, or sometimes I need to go on a field trip to an outcrop or a core lab to visualize what the rocks could look like in the subsurface. Or Maybe that day I make maps of the reservoir. It is forever changing in the geology profession.

Sam Lam: Legacy Camper

Once in a while, the Houston Museum of Natural Science Xplorations program gives children so much enthusiasm about science that they never really leave the museum. Sam Lam discovered the museum as a child with the Xplorations program, and has since never missed a summer at the museum. She now teaches some of the same summer camps she enjoyed when she was a kid.


HMNS: When did you start attending summer camp here? And why?

SL: I started attending camps at HMNS when I was 6 or 7 years old, around 1998. My mom worked downtown and decided to look into sending us to camp at HMNS. After just one week, I was hooked. From that point on, I kept pestering her to sign me up for Xplorations year after year. 


HMNS: What was your favorite class? What made it your favorite? Any stories from that class?

SL: My favorite class was Wizard Science Academy. Reading Harry Potter was a big part of my childhood, so it was very exciting to be able to attend a summer camp that incorporated science with a Hogwarts twist! I still remember dissecting an owl pellet and being convinced it was from Hedwig. I remember having Nicole Temple as my teacher and being so excited that she secretly let me switch out of the house that the Sorting Hat chose for me into the house of my choice.


HMNS: What is your favorite memory from summer camp?

SL: I took a camp called, “Thrills, Chills, and Disasters” that talked all about physics and the science behind amusement parks. As an end-of-the-week field trip that wrapped up all our learning, we were able to go to Astroworld to see the physics in action. I loved going around and riding rides with all of my camp friends. It was such a unique opportunity that I am lucky to have had!

HMNS: If you could go back to Xplorations Summer Camp for one week this summer, what class would you take and why?

SL: I would definitely sign up for Bedazzled! I have had the best time teaching that camp for the past few years. I think the best part of Bedazzled is the Spa Day on Friday when campers get to dress as comfortable as they’d like and pamper themselves for the day. A day with magnetic nail polish and a nice, relaxing mud mask? Sign me up! 


HMNS: What made you decide to come back and work at HMNS?

SL: When I was a camper, the Xplorations staff was always so enthusiastic and fun to be around. Because of them, I never wanted to leave camp when my mom came to pick me up. I wanted to keep the fun going and stay with them. When I officially “aged-out” of camp, I knew I wanted to come back and make camp a positive experience for others, just like the staff did for me.

HMNS: How did the Xplorations Summer Camp influence your life?

SL: During the summers, HMNS has been my second home for as long as I can remember and the people I have met there have become like another family to me. Some of the best friendships I have are with people I have met through Xplorations. Thanks to Xplorations and its amazing staff, I was able to meet and teach with fantastic teachers who inspired me to become a teacher myself. The best part of Xplorations Summer Camp is the people you meet—from the awesome campers, to the fun-loving TA’s and teachers, and the always cheerful and helpful education staff. My best memories from camp are because of them.
