We Celebrate Rivers

1. WE COLLECT RIVERS

Our journey began with wanderlust and a quirky hobby - collecting rivers. Today, we're a company and a network of freelancers, united by our passion for rivers. We "collect" them for diverse reasons - travel, education, fun, and even to fund our work. This project ignited a fire in us to protect these vital waterways. We raise public awareness by showcasing our collection in schools and museums, and by creating unique river-themed art and gifts.

2. WE MIX RIVERS

Rivers merge naturally at confluences, forming sacred sites for many cultures, such as the Dakota people's reverence for the Mississippi-Minnesota confluence. We aim to capture a similar essence, creating "unnatural confluences" by mixing waters from rivers which won't meet, like the Nile and Amazon. This artistic endeavor challenges the boundaries of geography, sparking conversations about interconnectedness of all water.
