CRRG Member Activities
CRRG publications are authored by the full 10-member body, and represent our collective thinking on critical Colorado River issues. But the majority of each member's professional life is dedicated to their individual research, writings, and outreach. This page is dedicated to highlighting those individual contributions. See each member's personal page for additional resources.
