76 Landslide of bedrock onto highway; a frequent problem for highway maintenance, sometimes necessitating blasting of large bedrock blocks.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n039
77 Landslide scarp behind house along mountain front in Weber County.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n053
78 Landslide scarplet "getting closer to home" in mountain subdivision.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n049
79 Landsliding of an abutment encroaching on the reservoir which is near its peak stage (elevation). Structures for impoundment of flood waters must be sited with strict regard for geological conditions.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n023
80 Large scale landsliding during construction of Interstate 80 in Echo Canyon. Bedding plane slide.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n041
81 Leakage through the undisturbed abutment of an earthfill dam, measured in a wooden weir.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n026
82 Looking across a dam towards a massive ancient landslide. Recent highway construction has rejuvenated landsliding just below the spillway; note receding hillside under arrow.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n029
83 Looking downstream from the crest of the same earthfill dam (p1274n026). Note urban area at mouth of canyon.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n027
84 Low sun angle illumination, vertical aerial photograph of large ancient landslide in urban environment at mouth of Ogden Canyon.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n057
85 Map of Bear Lake showing bottom contours of the lake and depth to bedrock beneath soft valley sediments. The delta-fan areas along the east shore are colored yellow to indicate another hazard. Response of the delta-fan soft sediments to earthquake vibrations is anticipated to be poor, almost certainly causing severe damage to structures built on these level areas. Different earth materials may be expected to behave differently when shaken in an earthquake. The closeness of the contours bounding the delta-fans indicates a steep front for each. Movement of material in an earthquake may be expected to occur towards these steep fronts.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n098
86 Map of portion of the Wasatch Front showing the Wasatch Fault Zone in relation to the Salt Lake City aqueduct system (with water system facilities as projected into the 20th Century). Map illustrates severity of the earthquake problem in urban Utah.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n095
87 Map of Utah showing the 5 major active fault zones in the state.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n085
88 Monument to campers who lost their lives in cloudburst flood in Sheep Creek Canyon, in Flaming Gorge National Recreational Area, 1963. Note: boulder on which bronze monument has been placed is striated and polished by glacial action in the ice age.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n012
89 Mud-flow debris cleared from residence after storm on Salt Lake City's East Bench.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n019
90 Mud-flow which occurred in same season in which photo was taken, in Tooele County. Cloudburst probably descended on the background watershed in the Oquirrh Range.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n015
91 Mud-rock flow from upper steep-walled tributary canyon into Echo Canyon (Summit County) and over Interstate 80. Note that one lane of traffic has been cleared of debris. Aerial photo July 1968.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n018
92 Multistory apartment house sitting astride the East Bench Fault of the Wasatch Fault Zone in Salt Lake City.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n092
93 Nose of sagebrush-covered debris pointing out into grassy valley, in Sanpete County. Debris deposit was a sharply defined mud-rock flow.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n014
94 Ogden Standard Examiner newspaper photograph of mudslide encroaching into dining room.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n054
95 The old drainage below the dam through the city is now the site of numerous houses. Severe destruction would result from the dam failure.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n028
96 Party of people viewing large landslide mass. Slide plane (surface along which mass of earth moved) is evident in photo half way down the exposed wall, sloping towards the party.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n058
97 Pavement of Big Cottonwood Canyon Road, east of Salt Lake City, torn up by cloudburst flood in August 1969.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n007
98 Photograph of a relief map using oblique illumination to highlight the topography. Note the steep slope along the east shore of Bear Lake. This slope marks the active Bear Lake Fault bounding the lake on the east. The lake sits in a graben, a downdropping block of earth.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n086
99 Weber Basin Job Corpsmen digging out mudslide debris from hillside house.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n055
100 Well points (small diameter water wells) used to dewater a hillside in loose sand to stabilize it after cut was made for roadway.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n066
