River of Time

This interactive web-based platform encourages curiosity by allowing visitors to explore their region, learn from scholars and primary sources, and collect virtual artifacts.

River of Time serves as a unique digital resource for institutions and the public, encouraging them to rediscover the world around them with new eyes, sharpened by research on history, science, and culture.

River of Time is built in the GRPM’s new open-source and web-based 3D authoring platform.

The Maple River's banks, with rocks, sticks, and boards. A boat is in the water in the upper right corner. The left side is full of brush and moss.

Explore River of Time's First Landmark: Maple Island

The Maple River, a former side channel of the Muskegon River, was once a logging river. Logging companies damaged this delicate ecosystem. Today, The Little Band of Ottawa Indians, the Muskegon River Watershed Assembly, local residents, and township county, state, federal, and non-profit partners are working on the Maple Restoration Project.

This StoryMap explores how Maple Island, formed by the Maple River channel, came to be, and what it might become. These stories were collected by researchers Gareth Baldrica-Franklin, Caroline Gottschalk, and Marty Holtgren.

This project is made possible by grants from the Michigan Humanities, an affiliate of the National Endowment for the Humanities and the Fremont Area Community Foundation.
