Day-Mutual Mine, Burnt Tree Fork, Spring Canyon, Helper, Carbon County, UT

Significance: The mine tipple is associated with events that have made significant contributions to the broad patterns of our history, i.e., early 20th century coal mining in Utah and the western United States. The tipple is an integral part of the overall Mutual mining operations as it evolved through the 20th century. It is an example of a mine support facility, designed for a particular function and constructed with cheap, locally available materials. It is one of the few surviving examples of wooden tipples remaining in the Spring Canyon district. The site retains integrity of setting and physical integrity and therefore conveys feeling and association with its period of historical significance.
