The Perspective series of talks continues Tuesday at Olympic National Park. The programs look at the historical, scientific and cultural aspects of the park and the Olympic Peninsula.

The series, in its 14th year, is co-sponsored by the park and Friends of Olympic National Park. It features programs by park staff and other experts from around the region.

Andy Ritchie, a hydrologist with the park, will give a program titled “It’s More Than Mud: Sediment Monitoring on the Elwha River.” The largest controlled release of sediment is occurring right now as the Glines Canyon Dam is removed on the Elwha River. Ritchie will talk about the efforts of park staff to monitor and understand the changes in sediment created during the Elwha River Restoration Project.

Here is the rest of the schedule:

Jan. 8: “Washing Ashore On Our Wild Coast” by Ian Miller, Washington Sea Grant, University of Washington. Miller will provide the latest information on the efforts to track marine debris generated by the March 2011 earthquake and tsunami in Japan.

Feb. 12: “Extending Our Understanding: Olympic Archeology” by Dave Conca, chief cultural resource management, Olympic National Park.

March 12: “Mapping the Human Ecology of the Olympic Peninsula” by David Banis, Portland State University. Human ecology mapping or “participatory mapping” offers a new approach to gathering social and cultural data.
