Our trip to Delintment Lake Oregon and our finds


Recommended Posts

Volksburgs

We went camping last weekend out at Delintment Lake in eastern Oregon.  We went to check out the ammonite fossils.  It was a great place!  Kids loved it.  Here are some of our finds.  Interesting area because you could dig in one area and it was really loose compacted clay and in another area less than a mile away it was hard slate type material that really needed some work to get it to split.  Naturally the slate material had the more robust ammonites.

Very nice!  Do you know what age these are?  I’m not that familiar with Oregon geology.

Thanks!  Yes from what I understand it is the middle Jurassic period.

Very interesting, thanks. Have to file that away in my memory banks for the next time I am in Oregon (haha, that could be decades from now, who knows!). Jurassic is one of those periods I personally don’t see very often (ever!).

This monograph will help you ID the ammonites.

I am passing through that area on the way to a Rose City Astronomers starparty at the field station further south, do you have GPS for the second location, I'd have an couple of hours I could "hunt"? Or more specific directions, I don't get to that area often.

 

Very nice fossils.

 

I down loaded the PDF, interesting stuff.
