Maps - no line is permanent
In conjunction with the Adult Summer Reading Program “Novel Destinations”
Sure, the Columbia River divides Washington and Oregon, but what explains the other boundaries of our state? Why are the county lines where they are, and how have they changed over the years?
Using maps from his own personal collection, historian Robert Hamm will show how cartographic processes changed from the 1500′s to the late 1800′s, and how people saw their world.
As Europeans and Americans began to understand the land masses, they drew boundaries based on presumption and on the political climate of the times. View authentic antique maps of the world and the U.S., particularly the West and specifically Oregon. Discover how Oregon county lines changed for various reasons.
Presenter Robert Hamm is an historian with special interest in maps and local history. He taught high school English for many years and was a school administrator in the Portland area. He currently runs a teacher-preparation program at a university in Portland.
