The principal source of helium is certain natural gas fields. The helium contents of more than 10,000 natural gases in various parts of the world have been measured (9). Helium concentrations of a few are Hsted in Table 2. In the United States, recovery of helium is economical only for helium-rich gases containing more than about 0.3 vol % belium. Most of the United States helium resources are located in the midcontinent and Rocky Mountain regions, and about 89% of the known United States supply is in the Hugoton field in Kansas, Oklahoma, and Texas the Keyes field in Oklahoma the Panhandle and Cliffside fields in Texas and the Riley Ridge area in Wyoming (11). 

With the downhole power available and the signal detection threshold at surface, Figure 4-254b gives the maximum depth that can be reached by the technique as a function of frequency. Assuming that phase-shift keying is used with two cycles per bit, in a 10 fi m area (such as the Rocky mountains) a depth of 2 km (6,000 ft) could be reached while transmitting 7 bits/s. 

The coastal race conforms to P. menziesii var. menziesii, whereas the inland races accord well with P. menziesii var. glauca (Beissn.) Franco, the form known from the Rocky Mountains. There is no established morphological equivalent to the Sierra Nevada race trees from that area are usually referred to var. menziesii. Zavarin and Snajberk (1975), however, sununarized differences between trees harvested in the Sierra Nevada Mountains and those harvested in northwestern California with regard to commercial applications, particularly in the manufacture of plywood or the production of composite materials (particle board). Differences in such factors... 

The remainder of this paper can be restricted to coals of North America, since this is the area for which we have data and in any case other contributors to this collection will deal with the coals of their own areas. The first statement above needs qualification we ourselves have no liquefaction data on Canadian coals, but Ignasiak et al. (48) present some in this collection.Relying, as in the earlier part of this paper, on geological information, we can say that the strata of the North Great Plains and Rocky Mountain provinces continue north into Canada, as does the Pacific province. Nova Scotia contains some Carboniferous coals related to those in the Eastern province. 

In remote alpine areas where anthropogenic pollution is limited, the retention of nutrients associated with trapped particles may become apparent. Case studies in two Rocky Mountain lakes (Kootenay and Arrows) indicated a reduced biological productivity, which is not compensated - as is usually the case in the European Alps -by enhanced nutrient input due to anthropogenic activities in the catchment [5]. 

Extraction of metals for 125 years generated extensive hazardous waste in the area around the Montana Rocky Mountains. About 5-7% of all rivers in Montana—more than 2000 km of streams—are contaminated by mining wastes at a level that impairs beneficial use of water (Montana Department of Health and Environmental Sciences, personal communication). Central to this contaminant burden is the wastes generated by mining and... 

In large areas of the world, the soils contain very little selenium in forms that can be taken up by plants. Crops produced in these areas are, therefore, very low in selenium. A selenium (deficiency in livestock is a serious problem. A deficiency causes a form of muscular dystrophy in younger animals and poor reproductive qualities in the adult animals. For prevention, sodium selenate or sodium selenite, sometimes augmented with vitamin E. is added in proper proportions to feedstuffs Some areas, including the Plains and Rocky Mountain states in the United States have soils that are rich in available selenium. Tn regions like these, selenium toxicity is a problem. The situation is particularly senous in Arizona, California, Montana, Nevada, New Mexico, and South Dakota.

The U.S. has vast coal resources of various geologic age (Carboniferous to Tertiary) and rank (lignite to anthracite). The regions with major coal resources in the conterminous U.S. are divided into six provinces Eastern, Interior, Rocky Mountains, Northern Great Plains, Gulf, and Pacific Coast. In addition, there are Alaskan coal fields (1). Information concerning geographic area, age, rank, reserve base, and sulfur abundance in coals from major basins in these provinces is summarized in Table I.
