Yucatan impact was the most recent encapsulation in Oregon. in school date was a ballpark figure - 48 million - 78 million.
Mr. Orr called me on the dates.Told him 48 -78. his reply was 36 - 38. ( Guy Rooth & Ewart Baldwin both agreed 48 - 78. U of O / Western State Monmouth,Oregon
Ewart Baldwin Oregon State. This is old news from 1996 )
Bill writes a nice letter. Now the Yucatan impact is 65 million.
Two more impacts most rocks wont talk about. 130 million & 240 million. Oregon on the west side has ash flow from Santiam river / an little north fork.
The 240 Antarctic was hit about 400 mile of South pole point.
on the Little north fork river mud flow from jawbone flats too the valley floor.
The parks are full of BACK WOOD, Was agatzied to long ago to ???? about.
The material breaks like opalite on a drop, many pieces.
Dry Fall State Park. Washington state. Over 70 glacier strata layers in the Columbia gorge. as it looks today the gorge is a very old crack.
Why Oregon is agate heavy.
