Snake River Scientific Drilling Project

 

Description

YellowstoneThe Snake River Plain represents a world-class example of active mantle plume volcanism in an intra-continental setting. Because it is young and tectonically undisturbed, the complete record of volcanic activity can be sampled only by drilling. The preliminary scientific plan is to core a series of 4-6 drill holes along the axis of the eastern and western Snake River Plain in order to study the geochemical and stratigraphic variations in plume-related volcanism in space and time.

Note that the effect of this geoid anomaly is the dominant feature in North America and impacts most of the western United States and parts of SW Canada.)
