1 Ground subsidence leaves this fireplug supported above the sidewalk in downtown Salt Lake City.Image
2 Breach of highway embankment on East Bench in Salt Lake City caused extensive damage to residential neighborhood downslope.Image
3 Multistory apartment house sitting astride the East Bench Fault of the Wasatch Fault Zone in Salt Lake City.Image
4 Damage to a house in Salt Lake City results from an unsatisfactory foundation. Note in particular the dropping of the arch over the doorway.Image
5 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.Image
6 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.Image
7 Closer view of slide cracks in high fill in Salt Lake City subdivision. Note housing density downslope.Image
8 Cloudburst flood caused erosion of the North Bench in Salt Lake City. Eroded channel begins where paved street ends.Image
9 Damage to the Salt Lake City Cemetery from a flood channeled in Perry's Hollow, a normally dry drainage course.Image
10 Pavement of Big Cottonwood Canyon Road, east of Salt Lake City, torn up by cloudburst flood in August 1969.1969-08Image
11 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.Image
12 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.Image
13 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.Image
14 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.Image
15 Mud-flow debris cleared from residence after storm on Salt Lake City's East Bench.Image
16 Slide of fill material in high, steep fill slope on Salt Lake City's North Bench.Image
17 Damage to newly laid curb and gutter on Salt Lake City's East Bench, resulting from August 1969 cloudburst.1969-08Image
18 Big Cottonwood Creek flooding in Salt Lake City. Numerous houses along its banks were flooded in 1952.1952Image
19 View across City Creek Canyon in Salt Lake City, showing amphitheater-like appearance of ancient landslide. Houses are short distance to left of landslide.Image
20 Closeup view of the fault shown in last slide (p1274n093).Image
