Comments: Paris, etc.

The soil is 100 times older in France than in California? Where did that factoid come from? The French?

Hi Jim, Actually you're right.. it's not a 100 times necessarily.. Doc Searls told me the 100 times figure, but actually it's probably more like 7 to 10 times as old in Europe as here. The reason is that our last volcanic activity was 15 million years ago and our last ice age was 2, and so people consider California to be young soil, and the Ag Department at UCDavis has documented this effect. But I think if you just taste like items from both places you'll notice the difference, regardless of the difference in age. It's still a lot. But you're right that I should have been more precise. However, this is a blog about things other than the age of soil, and I was relying on hearsay. But check out this site for some additional info: http://www.landinstitute.org/vnews/display.v/ART/2000/12/01/3aa90b0d9.

Mary,

There was a time when the North America continent was connected to the Euroasia continent. At that time the beginnings of soil formation was pretty much the same. Billions of years ago.

California's last volcanic activity was within the last two hundred years, and our volcanos are still considered active. (I'm from California too)

Glaciers carved out Yosemite less than 20,000 years ago, but then again glaciers are still carving out France today. There are still glaciers on Mount Shasta and Whitney today also.

But I still don't see where France's soil is 7 to 10 times the age of California's. We are both on the same geologic timeline.

Jim
