The Ancient and Honorable Order of E Clampus Vitus has its own Wikipedia page.

It covers the beginnings of ECV at the time of the California Gold Rush (First Incarnation) to its revival (Reestablishment) and Clampers of today (The Current ECV).

The Wikipedia page begins with:

The Ancient and Honorable Order of E Clampus Vitus (ECV) is a fraternal organization dedicated to the study and preservation of the heritage of the American West, especially the history of the Mother Lode and gold mining regions of the area. The fraternity is not sure if it is a "historical drinking society" or a "drinking historical society." There are chapters in California, Nevada, Arizona, Colorado, Utah, Washington, Idaho, Oregon and Outposts in other western states. Members call themselves "Clampers." The organization's name is in Dog Latin, and has no known meaning; even the spelling is disputed, sometimes appearing as "Clampus," "Clampsus," or "Clampsis." The motto of the Order, Credo Quia Absurdum, is generally interpreted as meaning "I believe it because it is absurd;" the proper Latin quotation Credo quia absurdum est, is from the Christian apologist Tertullian (c.160 – c.220 AD), who rejected rationalism and accepted a Gospel which addressed itself to the "non-rational levels of perception."

The page does mention in The Current ECV the practice of placing plaques of places and things. It also includes the 2006 plaque commemorating the 50th anniversary of Godzilla, King of the Monsters by Platrix Chapter No. 2 in Los Angeles (pictured at top).
