The Osher Life Long Learning Institute at Sierra College will present a day of intellectual and visual exploration as Tom Fisher presents “Origins of Yosemite and a Photographer’s Journey” on Nov. 17.

Fisher had a dual career in aerospace and archeology, designing for NASA astronauts. He has also conducted archaeological field research in China, Italy, and throughout Central America.

Fisher has visited and photographed major volcanoes all over the world and national parks in the U.S., China, Costa Rica and more.

In this particular two-part presentation, Fisher will focus on his visit to Yosemite.

The first session will examine how the area initially was created as geological processes such as plate tectonics, ice age phenomena, climate changes and environmental responses ravaged it over the many eons.

Clearly, plate tectonics and mountain uplifts created the park’s backbone, startlingly evident even today.

See the various geological stages and incredible results that carved the park over the millions of years evidenced by the scars and unusual — yet beautiful — formations left to view. Next, see an overview of the park as seen today and ending with a review of the written and photographic history of the site itself.

Session 2 will be the result of a photographer’s walk in the park. Tour the park from the lowest levels to the towering peaks, summits, domes, and see the glacier scattered massive boulders lain randomly all over the park.

Included will be the magnificent forests, bountiful lakes, and meadows all alive with melodious songs of flittering birds. Highlighted will be the kaleidoscopic rainbow of color and texture contrasted with the shear and stark tones of the incredible carved granite, sliced like butter.

The first session is from 10 a.m. to noon and the second session is from 1:30 to 3:30 p.m. Nov. 17 at Sierra College — Nevada County Campus, Room N12-103. General admission is $10 or free for Club OLLI members. Join Club OLLI now for $20 (membership expires July 31, 2015). Participants can attend one session or both.
