At last week’s luncheon, October 14, 2025, Rotary member Ed Patton gave a lecture on the Geology and Geography of the Eastern Snake River plain in Idaho. The area is an ancient track of the Yellowstone Hotspot and is home to Craters of the Moon National Monument.
The EBR1, (Energy Breeder Reactor) was developed there and powered the first town to be lit by nuclear power in the country.
Hagerman Fossil Beds located nearby depicts fossils of the earliest ancestors to modern day horses, donkeys and zebras. The Equus Simplicidens is the identifying term given to the horse fossils discovered in Hagerman, Idaho in 1928.
And on another significant note, the path of the Oregon Trail runs through the Eastern Snake River plain. We thank Ed for sharing his knowledge of the area with our club.
