This report discusses the emerging development of nationwide alert systems to recover missing adults, such as those with mental impairment (such as Alzheimer's disease), developmental disabilities, or suicidal tendencies. This report provides an overview of such alert systems in 11 states: Colorado, Delaware, Florida, Georgia, Kentucky, North Carolina, Ohio, Oklahoma, Rhode Island, Texas, and Virginia. This report also provides a discussion of issues for Congress to consider with respect to the federal role, if any, in developing state alert programs for missing adults.

Report discussing the regional geology, geomorphology, structure, mineral deposits, and details of the sedimentary and igneous rocks of the Placerville Quadrangle in Colorado.

A report regarding the areal geology of the Placerville Quadrangle, located in colorado. This report concerns work done on behalf of the division of Raw Materials of the U.S. Atomic Energy Commission.

A report about uranium in Colorado which oxidize to yield U(VI) before reacting significantly with other mineral constituents.

Report discussing the possible existence of pegmatites containing beryllium deposits in the granite stock in the vicinity of Mount Antero and White Mountain, Chaffee County, Colorado.

GEOTHERM sample file contains 225 records for Colorado. Three computer-generated indexes are found in appendices A, B, and C of this report. The indexes give one line summaries of each GEOTHERM record describing the chemistry of geothermal springs and wells in the sample file for Colorado. Each index is sorted by different variables to assist the user in locating geothermal records describing specific sites. Appendix A is sorted by the county name and the name of the source. Also given are latitude, longitude (both use decimal minutes), township, range, section, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix B is sorted by county, township, range, and section. Also given are name of source, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix C is first sorted into one-degree blocks by latitude, and longitude, and then by name of source. Adjacent one-degree blocks which are published as a 1:250,000 map are combined under the appropriate map name. Also given are GEOTHERM record identifier, and temperature (/sup 0/C). A bibliography is given in Appendix D.

A computer analysis of NURE-HSSR data.

We are making progress on our investigation of the mechanism of olefin exchange with Os{sub 2}(C{sub 2}H{sub 4})(CO){sub 8}. We are probing this system by kinetic study of the reaction of Os{sub 2}(C{sub 2}H{sub 4})(CO){sub 8} with butyl acrylate (BA) under various pressures of ethylene.

The report is divided into: vibrational models for surface ethylidenes (on catalyst surfaces); alpha vs beta hydrogen elimination in formation of propene from an osmacyclobutane; mechanism of formation and fragmentation of diosmacyclobutanes; reaction of dienes and allenes with diosmacyclobutanes; structure of Os(CO)[sub 4](C[sub 2]H[sub 4]), an osmacyclopropane; and reaction of [mu]-oxobis [(trifluoromethanesulfanato) (phenyl)iodine(III)] with Group 14 propargyl derivatives and a propargyl ether. 16 refs, figs.

"The possibility of radioactivity transport in the groundwater system as the result of a hypothetical maximum credible gas leak was evaluated." "The present study confirms the low radiation levels in the groundwater predicted in the initial calculations." (from Summary)

Report issued by the Bureau of Mines over exploration of the lead and zinc deposits of the Madonna Mine. Descriptions of the deposits are presented. This report includes tables, maps, and illustrations.

Report summarizing the results of geological exploration of the Atkinson Mesa area of Montrose County, Colorado and contains a brief description of the area's geology and ore deposits.

A report about how the U. S. Geological Survey explored the Atkinson Mesa area for uranium and vanadium bearing deposits from July 2, 1951, to June 18, 1953, with 397 diamond drill holes that totaled 261,251 feet.

A report regarding exploration for uranium deposits in the Atkinson Mesa area, Montrose County, Colorado. Concerns work done on behalf of the division of Raw Materials of the U.S. Atomic Energy Commission.

The following report covers a reconnaissance resource appraisal in pre-Morrison formations, particularly the Shinarump conglomerate, on the Colorado Plateu and adjoining regions during December of 1951. This report is preliminary in nature and the ideas are presented as a hypothesis to be tested by future work.

From purpose of study: The Vallecito Conglomerate of the Needle Mountains area in southwestern Colorado was studied to evaluate the uranium potential of the unit and to test the applicability of the uraniferous Precambrian pebble-conglomerate exploration model in this area. The main thrust of this project is the Vallecito Conglomerate, but the Uncompahgre Formation, which is also in the Needle Mountains area has basal conglomerate that was investigated in a reconnaissance mode. Five specific objectives have been formulated to meet the overall purpose of this project, and these include: a) Determine the uranium distribution in the Vallecito Conglomerate and the basal conglomerate of the Uncompahgre Formation. b) Evaluate the uranium resources of the area to the degree possible utilizing available information and personal field investigations. c) Test the validity of application of the Precambrian quartz-pebble conglomerate model to this area. d) Recommend detailed studies and delineate drilling sites in the area to further evaluate the uranium resources if warranted. e) Recommend additional geologic, geophysical and geochemical studies which would bear directly on evaluation of uranium resources of the Precambrian pebble conglomerates in the Needle Mountains area.

This report investigates the effects of the sewage-sludge recycling site and a landfill site on the ground-water system of Denver. It includes several maps.

This report examines the region of the Piceance Creek basin in Colorado so that the United States Bureau of Mines may develop plans for an underground oil-shale research facility in the center of the basin. It includes maps, charts, and graphs.

From introduction: The present report summarizes the indicated and inferred reserves which have been found to date by the drilling in Club Mesa, Montrose County of New Mexico, and includes an estimate of the potential reserves predicted for the area. It also includes a statement of plans for additional drilling. A final report will be prepared on the completion of the drilling planned for 1951.
