Ken Goehring


I retired from teaching in Spring 2014 after 40 years at the College of the Siskiyous in Weed, California. During these years I taught chemistry, biology, anthropology and computer programming and was Vice President of Technology Services for 2 years. I can be contacted at kengoehring @

In the last 20 years I've been studying the local pikas (see below)  I like to swim, hike and play fingerstyle guitar.I live with my wife (Linda Freeman), the spirit of our dog Pretzel, and many forest creatures a few miles west of Weed, California.

The Shasta Pika

At right is a picture of a pika (aka. cony, rock-rabbit, calling hare) Ochotona, that lives on Mt. Shasta. Pikas are related to rabbits and are rarely seen by hikers on the mountain because they mostly live at timberline and are very inconspicuous. On Mount Shasta, unlike most localities, they make very little noise.  I have been mapping their distribution on the mountain to compare with some hundred-year-old records. In the intermountain west pika populations are dwindling. This is probably due to global warming. I am interested to see if the same pattern is present on Mt. Shasta.  Visit for more information and my results.
