Agitation for the development of the western phosphate field as part of the national program of conservation and economic rehabilitation has, in the last three years, focused public attention on the phosphate reserves of Idaho, Montana, Wyoming and Utah. In every conference or discussion on this subject, the minds of Utah's representatives have naturally turned to the question, "What is Utah's share in this great natural resource?" Obviously nature pays no heed to political boundaries, and neither does the prosperity of Utah's citizens depend solely upon that which is circumscribed within the state's boundaries. Nonetheless, it is necessary for Utahns to measure their own natural resources, that they may be prepared to participate in any possible future development that will benefit not only their state, but the whole Rocky Mountain region.
