“On the coast of Oregon there is basalt rock - square miles of it.”
Look up the Columbia River Basalts. It is not recent, from Miocene age.
And, since I don’t know exactly where you are talking about, keep in mind that the Pacific NW is a volcanic hotbed, mostly Pliocene to Recent in age.
By the way, folks: that article is basically incoherent from any point of view, and is missing a lot of information to support anything close to what the writer is advocating. It doesn’t even mention depth from the surface of the earth. All it mentions is depth below water surface, which is meaningless to whatever point he is trying to make.
This article is par for the course for anything from this “institute.” I am obviously not a young earth believer, but citing anything from this “institute” or this author does not help your case with anyone. Their writing is poor, lacking in documentation, doesn’t reference any other publications than their own (usually), is unsound scientifically, and is basically a joke. I have followed the author and this “institute” for years, and it just gets worse, not better.
