1 Landslide in Empire Canyon, Park City, in altered bedrock. Mining of metallic ores occurs just up the canyon. Park City lies just down-canyon. Switchbacks on road to Brighton have been wiped out; A further failure two years later took away even more of the hillside and dammed the creek in the canyon. Oblique aerial view.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n044
2 A reservoir showing the earth-fill dam and a landslide block separated from the abutment in the foreground. Opposite abutment is an ancient landslide.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n024
3 Aerial photograph showing same swath and slide as on topographic map. Arrow points to displaced mass from swath behind it in mountain range.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n043
4 Ancient landslides show up on maps with scales as small as one inch to the mile. Three such ancient slides are pointed out along the mountain front in Juab County. Note swath of anomalous contours leading down to lowermost slide, obviously the path of bedrock which failed.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n042
5 Another example of dynamic forces at work in the geologic environment: pressure ridges formed in the salt crust of Utah's Bonneville Salt Flats. These ridges grow and shrink seasonally.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n074
6 Areas of carbonate rock (limestone) outcrops (in blue) in the vicinity of Bear Lake, Utah. Rocks range in age from Cambrian to Jurassic. Development on the outcrop area should be closely monitored to protect the underlying potable water aquifer.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n069
7 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
8 Bear Lake area map showing: (1) point of issue of Swan Creek Spring, (2) possible contributory sink holes (in red) in the Bear River Range, (3) precipitation (rain and snow) measuring stations (in bluelined blocks).P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n068
9 Big Cottonwood Creek flooding in Salt Lake City. Numerous houses along its banks were flooded in 1952.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n002
10 Blasting for an interstate highway in the immediate vicinity of a dam. Concrete railing of dam appears in lower right corner. Vibrations, whether natural (earthquake) or manmade, may damage structures on sensitive foundations.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n034
11 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 Collectionp1274n096
12 Breach of highway embankment on East Bench in Salt Lake City caused extensive damage to residential neighborhood downslope.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n006
13 Characteristic arcuate crack pattern in basement of house. Both vertical and lateral displacement is apparent.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n051
14 Closer view of head and foot of Park City landslide. Note tilt blocks at head of slide.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n045
15 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 Collectionp1274n061
16 Closeup of slide plane. Note deposition of white calcium carbonate by groundwater along slide plane. Arrow points to smooth, slickensided (grooved) surface on underside of sliding mass.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n059
17 Closeup view of the fault shown in last slide (p1274n093).P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n094
18 Cloudburst flood caused erosion of the North Bench in Salt Lake City. Eroded channel begins where paved street ends.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n005
19 Cone or fan of debris deposited on highway after cloudburst flood in Big Cottonwood Canyon.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n017
20 Crack down the highway centerline, showing displacement. U.S. 6 near Colton.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n040
21 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
22 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 Collectionp1274n079
23 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 Collectionp1274n083
24 Damage to newly laid curb and gutter on Salt Lake City's East Bench, resulting from August 1969 cloudburst.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n008
25 Damage to the Salt Lake City Cemetery from a flood channeled in Perry's Hollow, a normally dry drainage course.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n009
