Engineering plan for a proposed reservoir in Salt Lake City. Note the anomalous contour spacing under the arrow. This indicates that the hillside has slid in the past. Construction of a reservoir here would inundate the toe of an ancient landslide and destroy the balance and stability of the weak landslide mass. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n025 |

|
Slide of fill material in high, steep fill slope on Salt Lake City's North Bench. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n060 |

|
Closer view of slide cracks in high fill in Salt Lake City subdivision. Note housing density downslope. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n061 |

|
Groundwater, boiling up sand, at depth of a few feet in Sugarhouse, Salt Lake City, revealed by foundation excavation. Water probably arises along East Bench branch of the Wasatch Fault. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n065 |

Damage to a house in Salt Lake City results from an unsatisfactory foundation. Note in particular the dropping of the arch over the doorway. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n079 |

|
Damage to a major edifice in Salt Lake City resulted from differential settling of the two portions of the building. Arrow points to zone of distress which extends to foundation level. Note that window frames are askew. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n083 |

Closeup view of the fault shown in last slide (p1274n093). | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n094 |

|
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 Collection | p1274n095 |

|
Branch of the Wasatch Fault exposed in utility trench excavation in Salt Lake City. Hammer and field book are at the same stratigraphic horizon, indicating a displacement of 2 1/2 feet in late mudflow deposits, just below the ground surface. | P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collection | p1274n096 |
19 |
|
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 Collection | p1274n099 |
