Helicopter-assisted Data Collection Between Glen Canyon Dam and Lees Ferry
Helicopter-assisted Data Collection
The U.S. Geological Survey’s Grand Canyon Monitoring and Research Center (GCMRC) will conduct the overflight mission as a part of the Glen Canyon Adaptive Management Program.
Aerial images and topographic data will be collected to help monitor the effect of Glen Canyon Dam on downstream resources. Black and white panels (approximately 5 x 5 feet) which allow the data to be accurately positioned and adjusted, may be seen on the ground during this time. If you encounter any of the panels, please leave them undisturbed.
