|Extreme Cultural Landscapes:
New Archeological Research in Grand Canyon National Park
Ian Hough, Vanishing Treasures Archeologist
Wednesday, February 3, 2010 7–8:30 p.m.
Recent research in archeology at Grand Canyon National Park is revealing interesting patterns of human use of the resources in this dynamic environment. Through the ages, people developed a wide range of social and cultural strategies at Grand Canyon, from small-scale foraging and hunting to socially complex farming.
Ian Hough, who received his master of arts from Northern Arizona University in anthropology in 1999, will share some of the recent findings of archeological surveys, excavations and other research in the park.

|Mapping the Green: Vegetation Mapping at Grand Canyon
Mike Kearsley, Vegetation Mapping Coordinator
Wednesday, March 3, 2010 7–8:30 p.m.
With the greatest plant species diversity of any national park, extremes in elevation and topography, diverse geologic substrates, and influences from surrounding biogeographic provinces, the vegetative communities of Grand Canyon are as unique as you will find anywhere in the world.
Mike Kearsley, who earned a PhD in botany from Northern Arizona University in 1991, will give a brief history of vegetation mapping at Grand Canyon, describe the incredible diversity of plant communities found in the park and share some of the new insights into the canyon’s plant communities gained via vegetation mapping.

|Native Waters: Springs and Seeps of Grand Canyon National Park
Steve Rice, Hydrologist
Wednesday, April 7, 2010 7–8:30 p.m.
The springs and seeps of Grand Canyon are places of exceptional natural beauty that provide water and shelter in an otherwise arid environment. Springs also support diverse riparian vegetation and are often locations of substantial cultural significance. Hundreds of springs and seeps exist in the park, yet little is known about most of them.
Park Hydrologist Steve Rice, who received his master of science in geology from Northern Arizona University in 2007, will provide an overview of the hydrologic system that supports the canyon’s springs and seeps. He will also discuss activities and processes that threaten them, and the development of new protocols for baseline-data collection, interpretation and monitoring.
