1920's?

One remarkable thing about Barringer Crater was that even through the mid-60's (until Apollo landed!) there was FIERCE opposition to the theory that the moon's craters were due to meteor impact.

Continental drift was opposed since it was first proposed seriously in the 1920's .... until the seabed surveys in the late 60's showed the undersea mountain ridges in the north pacific WERE more recent than the floor further from the rift zones.
