Infrared survey of the Pisgah Crater area, San Bernardino County, California - a geologic interpretation
Stephen J. Gawarecki
1968, Open-File Report 69-104
The infrared survey of the Pisgah Crater Area, San Bernardino County, California was primarily undertaken to establish parameters by which rock types, structures, and textures peculiar to this locale could be recognized or differentiated. A secondary purpose was to provide an adequate evaluation and calibration of airborne and ground-based instruments...
Measurement of peak discharge at culverts by indirect methods
George Lawrence Bodhaine
1968, Techniques of Water-Resources Investigations 03-A3
This chapter classifies culvert flow into six types, gives discharge equations based on continuity and energy equations, and describes procedures for measuring peak discharges using culverts in the field. Discharge coefficients for a variety of geometries and flow types arc given. Ten examples detail step-by-step computation procedures....
Geology of the Gore Canyon-Kremmling area, Grand County, Colorado
C.S. Venable Barclay
1968, Open-File Report 68-3
The Gore Canyon-Kremmling area is in the southwestern portion of the Kremmling 15-minute quadrangle, Colorado. Precambrian rocks are biotite gneiss, the Boulder Creek Granodiorite, granophyre dikes, and quartz veins. The Boulder Creek intrudes the biotite gneiss, and both of these units are cut by north-northwest-trending granophyre dikes and quartz veins....
