<br />Discover.r in early 1967 of the prolific Dineh-bi-Keyeh field in Ari-
<br />zona, 30 miles south of the Four Corners, ~ill undoubtedly ~ause drilling
<br />in the San Juan Area to increase in future years. Also the presence of
<br />the Greater Aneth oil field and numerous adjoining fields of moderate size
<br />and the hi&~ly concentrated Bnd prolific Lisbon Field in the o?rthern part
<br />of the area indicates that organic source beds within the area have gen-
<br />erated major reser~es of oil. Known structural Bnd stratigraphic complexi-
<br />ties and variations throughout the area provide a large number of potential
<br />entrapments for oil Bod gas. The only missing factor is additional drill-
<br />ing, and this can be expected to take place in future years.

<br />Uranium and Related Metals
<br />
<br />Uranium and related metals have been important to the San Juan Area
<br />since the beginning of the century ~hen the Curies and others isolated
<br />uranium and radium and described their peculiar radioactive properties.
<br />Several "boom" periods of' exploration and development have been experi-
<br />enced, first for radium, then for vanadium, and finally for uranium. The
<br />discovery of the nuclear properties of atoms instigated the uranium boom
<br />of the fifties and through Government subsidy many incentives ~ere of-
<br />fered for the discovery and production of these ores. The boom reached
<br />such a frenzy that literally all surface outcroppings in the study area
<br />were examined by prospectors. Uranium mining spurted to a point where
<br />production became more than the Goverr~ent--really the only customer--
<br />could handle. Stretch-out programs ~ere set up whereby the uranium min-
<br />ing industry would be limited but not destroyed.
