Donate to Great Circle Alliance

The Friends of the Great Circle Alliance (GCA) is a group of individuals, organizations, and businesses joining with GCA as allies, reanimating indigenous history, art and culture.

Our purpose is to bring together Native and non-Native people – artists, scholars, archeologists, and local communities – to generate more in-depth appreciation and engagement with the Hopewell earthworks, connecting ancestral voices with contemporary people.

The Great Circle Alliance is an independent nonprofit organization. We operate an informal alliance with Native Americans connected to the sites, the OSU Newark Earthworks Center, the Ohio History Connection, and Denison University.

The Friends of the Great Circle Alliance will:

  • Further the educational and interpretive activities at the Newark Earthworks
  • Provide volunteer support for site programs, projects, and special events
  • Support the GCA Artist in Residence program
  • Provide input in long-range program planning


Membership levels allow everyone to participate. No matter what amount you contribute, we appreciate your investment in the Alliance and the purpose we serve.

  • GCA SUPPORTER ($30): As a GCA Supporter you will receive our regular newsletter and be invited to volunteer with our public programs. If you’re unfamiliar with Hopewell culture and the Newark Earthworks, GCA can supply resources for exploring the extensive culture of the indigenous people of Ohio.
  • GCA ADVOCATE ($50 – $500): GCA Advocates believe in raising awareness of the indigenous worldview based on valuing community and caring for the Earth. In addition to our regular newsletter and volunteer opportunities, GCA Advocates receive personal invitations to programs and events, including private tours of the Newark Earthworks. Your input will influence our long range program planning.
  • GCA ALLY ($500 – $2500): Become a GCA ALLY and contribute to the resurgence in indigenous history, art and culture. In particular you will be supporting GCA in bringing Native American artists to the Newark Earthworks.
