Thundereggs from Jefferson County, Oregon, USA

Madras Area

Richardson Ranch (Kennedy Ranch) Numbered Beds

As far as I can make out, most of the Kennedy Ranch thunderegg area is now a part of the Richardson Ranch and the beds there now form the Richard numbered beds (1 to 6, though #4 seems mysteriously not to exist). However, the name Kennedy is still often encountered, partly to distinguish this patch of ground from the old Priday area (also now Richardson Ranch) but mostly signifying older specimens collected when the property was still known by that name. I have preserved the tags in these beds as they were when I aquired them.

Richardson Ranch (Priday) Named Beds etc.

The named beds on Richardson Ranch come from an area seperate to the numbered beds (the old Kennedy beds). These are the famous Richardson thundereggs, some among the most common and recognisable in the world. These were originally known under the name Priday.

These are beds that lie outside the Richardson Ranch itself yet are clearly closely related. Either they are merely on the other side of a fence or are far away but showing signs of a similar geology.
