Halloween morning, 2025 — in the SAFE Credit Union Plaza, a sculpture of a black plastic body bag sits on a wooden pedestal surrounded by a fence.
A piece of paper was taped to the fence that read:
“This sculptural work serves as both memorial and misremembering – a marker for those who looked upon Lunar Specimen 12038,7, a fragment of the moon brought to Earth in 1969, and affectionately called it “salt lick.”

The body bag sat in place of a sculpture that had gone missing. The missing sculpture was made of a clear acrylic resin and was modeled after the shape of a moon rock brought back from the 1969 Apollo 12 moon landing.
But to a lot of people, it looked like a salt lick—like for horses.
Lunar Specimen 12038,7, or as it is now officially known as “Murmur,” was installed in 2021. As time wore on, it grew increasingly guarded. First cones, then caution tape, then a fence.
Allie Weill lives about a fifteen minute walk from it and, when going on walks around the neighborhood, loved seeing the sculpture.
Then, one night in late September, Murmur was gone. She was concerned.
“I had this idea come to me to put up a missing sign. Much like someone would put up a lost cat or dog sign walking around the neighborhood,” Weill said. “I often see those kinds of signs as well. And I thought it would just bring a little joy to anyone who happened to see it.”
Weill’s missing poster linked to a Google Form where people could share their love for Murmur, memories, and the purported whereabouts of the big pink moon rock.

One of Weill’s favorites read:
“In the cradle of my heart, the arms of my memories,” the entry read. “Please, my pink goddess, return and bless this convention center.”
Another, maybe a little less reverent, read:
“Perhaps a large horse alien took it back to its lair to lick.”
However, one entry that read “It went home for the holidays, it’ll return refreshed and renewed,” was right on the mark.

Jiayi Young, the artist who created Murmur, had no idea that the neighborhood would miss it as much as it did.
She’s a design professor at UC Davis, and when the 8,000 pound rock was fully removed, it did go back home to her shop on campus. It needed some repairs after some particularly forceful public engagement.
“There were unfortunately two very harsh skateboarding impacts to the sculpture that created damage,” Young said.
So, after class was out for the holidays, Murmur is in fact returning this week to the convention center — refreshed and renewed.

Weill said she’s happy to see the public art piece back and part of the public space, and she’s glad to see people responding to her posters.
“I’m so glad for the people in the community who engaged in some way with my little bit of mischief back in the fall,” Weill said. “That’s one of the joys of living in a city like Sacramento.”
Young said she made the piece as an ode to human curiosity, and the way space has played a role in history. She said that if you listen closely to the piece you can hear its namesake: a murmur of outer space.
“That’s the cosmic microwave map of the known universe. The sound is a mapping of all the pixels on that map, left to right, top to bottom,” Young said, “As if we’re actually sweeping the entire known universe.”
Here’s a sample of the audio from Murmur, courtesy of Jiayi Young:
According to Young, she wanted to make a piece symbolic of humanity’s curiosity, but also the consequences of that curiosity.
“We are incredibly courageous in tackling those curiosities and solve problems, make discoveries at the same time,” Young said. “We are also very good at extracting, exploiting, exploiting the resources that we have on Earth or beyond.”
She felt inspired by the role this curiosity has played in the United States’ history as a global power.
“Another train of thought that went into Murmur was [what] the moon landing, the backdrop of the moon landing had to do with the Cold War,” Young said. “[What] political and geopolitical tensions between East and West had to do with the race with the Soviet Union.”
Young has made quite a few pieces of public art over her career, and she said she always comes back to a particular quote of the late Jane Goodall when making pieces that are for the public.
“I want to make sure that you all understand that each and every one of you have a role to play. You may not know it, you may not find it, but your life matters,” Young said. “And you’re here for a reason. And I want you to understand that we are part of the natural world. And even today, where the planet is dark, there still is hope.”
Murmur sits in the SAFE Credit Union Plaza at 1301 L St in downtown Sacramento, CA.
