2851 Hydrograph depicting flow for the year 1945 of Utah's second largest spring, Swan Creek Spring, west of Bear Lake in northern Utah. Note the fluctuation in flow from April to September. Note also rapid response to spring snowmelt (April and May) and rainfall (June and July). The rock from which the spring issues (aquifer) is limestone. The graph illustrates the importance of controlling development on limestone terrain.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n067
2852 Surficial or shallow ground water is subject to pollution from buried solid wastes. Leaching of the wastes can occur in time. This excavation is for a land fill operation where ground water was encountered at a depth of less than 6 feet.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n072
2853 Swelling of clay soil as it takes on additional moisture heaved up this garage floor and cracked it.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n075
2854 This water storage reservoir has failed; it was placed improperly upon a stratum of gypsum (white layers in photo) which partially dissolved.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n076
2855 Crack in soil alongside reservoir, showing subsidence. Reservoir was the only water storage facility serving several thousand people.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n077
2856 These twin tanks deverge from bottom to top. Differential settling of their foundations caused this.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n078
2857 Arrow points to incipient failure of an excavation wall for a foundation for a multistory office building. Material is horizontally stratified Lake Bonneville silts and sands.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n080
2858 The circumstances here probably make a utility trench cave-in inevitable. A perched water table is sapping fine sand from underneath a thick silt bed, leaving the latter unsupported. Failure will be too rapid for escape of a workman who may be in the trench at the wrong moment.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n082

2860 Exposure of a branch of the Wasatch Fault in a sand and gravel pit along the mountain front. Amount of displacement is indeterminable from the stratigraphy exposed. Note that the fault is planar and stands out with relative resistance to the elements despite lack of cementation of the sand and gravel.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n090
2861 Steep, high, artificial fill slopes in or near the Wasatch Fault Zone. Downslope from these fills lie dense residential developments. Atop these fills are residences. How may these earth materials be expected to react to seismic vibrations?P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n100
2862 Car dumper at the Magna concentrating mill. The car, with between 85 and 100 tons of ore, is turned completely over in the unloading process.P1477 Gibb R. Madsen Photograph Collectionp1477n01_01_04
2863 Ball mills at the Magna mill. Each cylinder contains about sixty tons of steel balls, which roll as the cylinder turns, grinding the ore between the balls.P1477 Gibb R. Madsen Photograph Collectionp1477n01_01_05
