Upriver: Stromatolite, Allentown Formation

By Heidi Wiren Bartlett, 2022 resident artist
Collaborators: Dave Sunderlin and Michael McGuire
Rock, 2022

A stromatolite rock is one of the five pieces in the art project called Upriver by Heidi Wiren Bartlett on the Karl Stirner Arts Trail in Easton, Pennsylvania.

Easton’s paleogeographic position was tropical around 500 million years ago. Rocks such as this piece of Allentown Formation — which stands at 29″ x 45″ x 22″ — reflect a time when limey mud was laid down in shallow seas. This stone is evidence that calm azure waters contained stromatolite laminations accumulated with the help of photosynthetic microbes. This specimen also records a tumultuous storm event with torn-up, angular fragments — a fossilized hurricane.

Debuting in July 2022, Upriver was a conceptual public art piece researched, developed, directed, and constructed by Bartlett, who enlisted actors, artists, scholars, geologists, engineers, musicians, a mule, and a draft horse. Each element was constructed to reflect the potent history of the Lehigh Valley and the myths of “The Place at the Forks.” Director of photography was Margaret Champagne.

Bartlett is a filmmaker, sculptor, and performance artist from the Great Plains. Her work is concerned with the portrayal, oppression, and subversive existence of women in America today. She sees her body as an object of power and vulnerability, and she sees nature and its processes in the same way. Together these inspire a practice that illuminates the overlooked and forgotten. Whether creating laborious actions or objects, she blurs the line between public and private, deconstructing notions of gender, race, and corporeality. She holds an MA and MFA in intermedia from the University of Iowa. A Pittsburgh resident, she is an artist and designer at Carnegie Mellon University and co-founder of Propelled Animals, a transdisciplinary arts and social justice collective.

In 2021, Bartlett’s work was featured in Resonance: The Journal of Sound and Culture, she was a Max Kade Fellow at Lafayette College, an artist-in-residence at the Kelly Strayhorn Theater in Pittsburgh, and a National Performance Network Artist Engagement Fund and Storytelling Grant awardee. She was nominated for the United States Artists Fellowship and selected as a roundtable scholar for the spring 2020 What Can Museums Become? symposium hosted by the Stanley Museum of Art at the University of Iowa.

Her studio is housed at the Brew House Association in Pittsburgh, and she is an artist-in-residence at High Concepts Labs in Chicago.

“The deep time recorded in the Pennsylvanian landscape is unlike anything I’ve known, including the geologic time that birthed the American Industrial Revolution. There’s magic in these mountains, and they have much to tell,” she says.
