Omak Rock , also known as Balance Rock , is a balancing rock in the Colville Indian Reservation , in the U.S. state of Washington . Located within the Greater Omak Area of the Okanogan Country , the glacial erratic is about from Omak Lake . It is positioned within the vicinity of the 1872 North Cascades earthquake , which it survived . The fact of its survival has been the basis of studies to help determine the acceleration and intensity of the quake . Some believe that the epicenter of the earthquake may have been very close to Omak Rock . The Confederated Tribes of the Colville Reservation believe that the rock represents a symbol of nature 's perfection in the region
