I honestly don't know - I've spent a bit of time looking at other photos and my inexperience lets me down. The colour is a slightly pinkish red - less red than Winnie's examples, but her examples have a closer patterning match than Galen's. The opaqueness of the white is like the most opaque examples in Galen's photo but not the typical, but I understand they do vary... Looking at other sites it looks like some examples but not others - it's fairly close to Bob's handgathered photo, but with less orange (there's some but not much): http://www.marblecollecting.com/marble-reference/online-marble-id-guide/christensen-agate-co/
I'd appreciate further thoughts before I contact LoM.
