Marston Ranch Jasper is a colorful variety of breciatted jasper that only occurs at the Marston Ranch in Jefferson County, Oregon. Jefferson County falls within the Ash Butte, a geologic formation that resulted from settling of volcanic ash along its sides. This environment is perfect for both jasper and petrified wood to form. The exact origins surrounding whether or not this is indeed jasper-replaced petrified wood or a type of jasper formed by a different mechanism is still up for debate.
