7.7" Jasper Replaced Petrified Wood Bookends - Marston Ranch, Oregon

Jasper Replaced Petrified Wood Bookends - Marston Ranch, Oregon #271133

This is a very unique pair of bookends made from jasper replaced petrified wood from Marston Ranch, Oregon. They are polished on one face and two edges to show the detail, and are also felt covered on two end faces to protect the surfaces they come in contact with. The jasper replacement left a beautiful coloration with hues of yellow and spots of red and green, but destroyed the detail that would allow for the type of tree to be identified.

Each bookend slightly varies in size, with the one measuring 7.7" tall, 5.9" wide and 1.7" thick, while the other is 7.4" tall, 5.9" wide and 1.7" thick.

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.
