Uncovering Ancient Landscapes of the Rio de Flag. A walk with Richard Holm, NAU Professor Emeritus

We will meet at the SW corner of the Sams Club parking lot and walk down South Babbitt Drive to the Rio de Flag near the treatment plant. From there we will head downstream past the I-40 wetlands
and continue towards the Little America property. Wear comfortable walking shoes and be prepared to walk approximately 3 miles

Our walk will explore the ancient landscapes of Flagstaff visible from the FUTS trail along the Rio de Flag. Richard Holm will show how lava flowed down and filled small canyons. Later floods re-excavated the drainages where the trail is now located. He will demonstrate field evidence for reversal of flow.


Richard Holm is the author of the recent publication from the Arizona Geological Survey pictured above. The walk will encompass Trail 2, stops 6-8 described in the publication. This work can be downloaded for free by clicking on the link below.

Welcome Kelly Burke!

Welcome Kelly Burke!

We are pleased to introduce you to Kelly Burke, Friends of the Rio de Flag’s new Watershed Group Coordinator!

As Watershed Group Coordinator, Kelly will work with diverse stakeholders and the public to help expand and formalize the Watershed Group and create a watershed plan for the Rio de Flag. The goal of the plan is to outline watershed needs and opportunities, especially as these relate to restoration. This two-year project is being funded by a Bureau of Reclamation WaterSMART Cooperative Watershed Management grant (Phase I).

Kelly brings a wealth of experience and training to the Friends of the Rio. As cofounder and Director of the Grand Canyon Wildlands Council, a science-based conservation organization in Flagstaff, Kelly has overseen the completion of major restoration projects, including a collaborative riparian restoration plan with the National Park Service for the Glen Canyon Reach of the Colorado River. Her background is in structural geology, hydrology and aqueous geochemistry, fluvial geomorphology, geoarcheology, and springs and riparian restoration, which she combines with experience in coordinating field projects and conservation campaigns, building partnerships, community engagement, nonprofit leadership, and fundraising.

Kelly loves people, water, and wild nature with a common concern for their health, free movement, and full lives. We are thrilled to have Kelly join the organization and excited to have her strong leadership and positive attitude guide us through watershed planning in Flagstaff and the surrounding communities.

Please welcome Kelly!
