Making most geologists antidiluvian.
When I was in grad school in the seventies of the last century, I chanced upon an article in Science magazine about evidence for water channels on Mars. The article compared the situation to the evidence for the Spokane Flood put forth by Harlen Bretz in the 1920s. Geologists were indeed "antidiluvian" and Bretz pretty much sacrificed his career to his advocacy of this interpretation. Of course, he was subsequently vindicated.
When I debated Henry Morris as a "local challenger" back in the eighties, I contrasted the satellite photos of the Spokane badlands with those of the Grand Canyon. In the first case, you can see the "braided stream" effect formed by water rushing over a broad area. In the second case you can see the dendritic ( tree-like ) pattern caused by local drainage, clear and visually compelling evidence against the catastrophic formation of the Grand Canyon which many creationists advocate.
