Expedition: Then and now

From May 24 through July 31, 2019, the Sesquecentennial Colorado River Exploring Expedition will be following John Wesley Powell's pathway from Green River WY to the Virgin River near the AZ-CA border. Here's how you can follow and learn about both expeditions.

While USGS is marking this occasion as an opportunity to highlight the science of the Colorado River Basin, it’s important to note that indigenous people had been present in the area for over 15,000 years, and tribes in the 19th century had a great deal of knowledge about the river and ecosystems of their homeland.  Western migration by white settlers brought conflict and devastating consequences to Native peoples and their natural and cultural resources. In acknowledgement of this, we hope to hear about Native American perspectives on river science, including traditional cultural practices, during community outreach events and discussions throughout this year's expedition.
