51 Incipient landslide failure on subdivision road. Note characteristic arcuate configuration of ground surface, also patching along crack.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n046
52 Landslide along a scarp of the East Bench Fault in Salt Lake City. No earth tremor is known to have triggered this slide, but an earthquake could trigger similar slides, given similar geologic conditions.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n099
53 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
54 Landslide scarp behind house along mountain front in Weber County.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n053
55 Landslide scarplet "getting closer to home" in mountain subdivision.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n049
56 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
57 Large scale landsliding during construction of Interstate 80 in Echo Canyon. Bedding plane slide.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n041
58 Leakage through the undisturbed abutment of an earthfill dam, measured in a wooden weir.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n026
59 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
60 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
61 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
62 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
63 Map of Utah showing the 5 major active fault zones in the state.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n085
64 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
65 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
66 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
67 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
68 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
69 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
70 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
71 Ogden Standard Examiner newspaper photograph of mudslide encroaching into dining room.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n054
72 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
73 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
74 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
75 Portion of the East Bench along the mountain front in Salt Lake County. It has been dissected by strands of the Wasatch Fault. Since this photo was taken a housing development has been built on this terrain.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n091
