Artists Aron Altmark and Rachel Stoll Shed Light on Santa Cruz’s Best Kept Secret

Visitors flock to Santa Cruz for the redwoods and the coastline. They come to surf world-class waves, to catch sight of a blue whale in the Monterey Bay, and to experience the classic charm of the Santa Cruz Beach Boardwalk. Santa Cruz has a well-kept secret, however, that’s hidden in plain sight. It’s admittedly still a diamond in the rough but a cavalry of local artists, environmentalists, and community builders have plans to change that.

So, what is this precious local gem that’s been sitting right under everyone’s noses? It’s our city’s primary water source, a vibrant wildlife habitat, and soon-to-be community gathering place: the San Lorenzo River.

If you’ve spent time along the San Lorenzo it was probably in its wildest state up in the mountains as it winds through Henry Cowell State Park. Few locals or visitors, however, spend much time along its urban riverfront. This ‘domesticated’ stretch slowly meanders from The Tannery Arts Center, through Downtown, past the Santa Cruz Beach Boardwalk, and finally spills into the Pacific Ocean.

This stretch, called the Santa Cruz Riverwalk, is the City’s longest park and the focal point of the vibrant Ebb & Flow Festival, a collaboration between artists and environmentalists that will reassure even the most nostalgic old-timer that Santa Cruz’s unique culture is alive and well.

Last season, we met with two festival artists at the Radius Gallery in the Tannery to learn about their 2018 installation along the San Lorenzo River.

Aron Altmark and Rachel Stoll of Visual Endeavors travel often for work, creating mesmerizing light shows for live entertainment experiences throughout the country and across the globe. They’ve worked behind the scenes at parties for tech giants like Amazon and Spotify, lit the stage at popular music festivals like Coachella and Life is Beautiful, and transformed the stadium for WrestleMania, one of the largest live TV and sporting events in the world.

Altmark and Stoll admit their work allows them to live anywhere in the world, but since 2015, they’ve chosen Santa Cruz as their home for its natural beauty, laid back beach vibes, and the inspiring community of artists and other innovative residents. “We’re really big into mountain biking and I’m a trail runner as well so the outdoor opportunities and the culture here was a good fit for us,” says Stoll.

The creative duo jumped at the opportunity to give back to their community through a truly unique public art installation for the Ebb & Flow Festival. Their animated light sculpture spanned the length of the Soquel Bridge, quite literally highlighting a section of the river that’s still widely ignored even though people drive over it countless times per day.

“We’re trying to create a centerpiece in downtown that brings people together and is a point of reflection using light as a medium,” explains Altmark. “I’ve always loved the idea of making public art without any barrier to entry. For this piece, we can construct something that everyone can see any time of day and encourage people to learn more about the river.”

The 2018 Ebb & Flow Festival was titled, River Motion, the art piece shared the story of the San Lorenzo River by illuminating a sculpture with a rainbow of colors that pulsate and undulate at varying frequencies, reflecting data points pulled from the river.

With help from the Coastal Watershed Council, U.S. Geological Survey, and the City of Santa Cruz, these data points will include the river’s depth, volume, and speed as well as temperature, salinity, turbidity, and pH. Altmark and Stoll translated this data into patterns of moving, colored light that reflect the dynamic ecosystem flowing beneath Santa Cruz pedestrians, bicyclists, and drivers.

“What you see in the fall is going to be totally different from what you see in the spring because of the changes in the data,” says Altmark. “As the watershed changes the lights will reflect that.”

2019 Ebb & Flow Festival

The Ebb & Flow Festival promises a weekend of live music, dance performances, dance parties, art-making, and countless other surprises. Michelle Williams, Executive Director of Arts Council Santa Cruz County, has high expectations for the 2019 festival. “This year will be epic,” she says. The full event/festival lineup will be live on the Ebb & Flow website on June 1, 2019.

Ebb & Flow will be a two-day event, starting Friday, June 7, 2019 on Cooper Street in Downtown Santa Cruz. (If you’re not here in June, you can still enjoy the Ebb & Flow River Arts Festival which will remain on the bridge for about one year.) Expect live music, dancing, and art projects outside in the street and in Abbott Square.

“The Ebb & Flow Festival gives you a flavor of just how extraordinary our arts and our environmental community is,” says Williams. “It’s this opportunity to step into a homegrown and yet totally extraordinary experience of what Santa Cruz has to offer. It’s so creative and such a great event for families. If I stumbled upon this as a visitor, I would think I had struck gold.”
