Last Rush for the Wild West exposes how impending tar sands and oil shale mining would destroy massive landscapes in Utah and put the already imperiled Colorado River Watershed at risk. Utah has approved the USA's precedent setting tar sands mine despite widespread health impacts of similar projects in northern Canada. This film asserts that the risks are not worth it, while refuting claims that tar sands and oil shale mining would create better economic conditions and lead our nation toward energy independence. Last Rush raises the collective voices of Utah citizens along with indigenous elders in Canada as they call for an end of the practice.
