I have only recently seen some here in the Omaha Area. Okay, it was really last fall, not too recent. They were also olive in color, with a brown cast to them.

In Utah (Northern area, Provo River, Spanish Fork Canyon) they were more of a brown to red with many being bright Orange when they stayed in the sun too long.

Some of the Utah ones ended up a dark red in a pot of Crab Boil on more than one occasion.
