PASCO -- Author, teacher and naturalist Jack Nisbet will talk about Canadian fur agent and cartographer David Thompson at 10 a.m. July 9 at Sacajawea State Park Interpretive Center, 2503 Sacajawea Park Road.
Thompson connected the first formal survey of the upper Columbia drainage with the work of Lewis and Clark on the lower half. Nisbet will compare the back story, approach and long-term influence of Thompson's work with that of the Corps of Discovery and trace the lineage of Thompson's remarkable maps of western North America.
Nisbet is author of several works that explore the human and natural history of the Intermountain West, including "Purple Flat Top," "Singing Grass Burning Sage" and "Visible Bones," as well as two books about David Thompson: "Sources of the River" and "The Mapmaker's Eye."
Washington State Historical Society Director David Nicandri calls him "one of the Northwest's great storytellers." The Pacific Northwest Booksellers Association named his most recent project, "The Collector: David Douglas and the Natural History of the Northwest," as one of their 2010 Books of the Year.
Nisbet will also sign copies of his books after the presentation. For more information, call 509-545-2361.
