26 Erosion of a hillside fill- more than 2 feet from a single cloudburst. Sediment is deposited at foot of slope in neighbor's back yard.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n010
27 Erosion of fill placed from home construction. Deposition of material in foreground gives braided stream appearance.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n011
28 Excavation and trench cave-ins occur all too frequently along Utah's Wasatch Front. Each year sees its fatalities from this cause.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n081
29 Excavation for a covered distribution reservoir is pointed out in the photo. Note that drainages have been truncated. Reservoir is in an urban area with considerable development downslope. Geologic materials comprising the site are unstable. Geologic faults are mapped bounding the site, and springs issue from excavation walls and floor.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n035
30 Expensive new house being constructed on banks of perennial stream which is subject to flood each spring and throughout the summer. Should not a form of flood plain zoning be in effect?P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n021
31 Exposure of a branch of the Wasatch Fault in a sand and gravel pit along the mountain front. Amount of displacement is indeterminable from the stratigraphy exposed. Note that the fault is planar and stands out with relative resistance to the elements despite lack of cementation of the sand and gravel.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n090
32 Failure of front yard before completion of home construction in mountain subdivision.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n050
33 Failure of ground bordering on a covered distribution reservoir. Hammer provides scale on displacement scarp.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n036
34 Failure of undisturbed hillside bordering on Bear Lake (to left just off edge of road and photo). This hillside is particularly valuable as view property for resort development, yet is failing without any terrain modification by man.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n048
35 Fault trace of the active Wasatch Fault across a glacial moraine at the mouth of Little Cottonwood Canyon in Salt Lake County. Note that the fault scarplet is virtually unvegetated, indicative of its recency.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n088
36 Fault trace revealed in the foundation excavation for the building depicted in the preceding photograph (p1274n092).P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n093
37 Flooding from snow runoff, mouth of Weber Canyon. Weber River has overtopped its normal channel banks and covers its flood plain. Periodically, structures situated on this flood plain become inundated. Note: ancient Lake Bonneville terraces may be seen on the mountain front.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n001
38 Foothill terrain at base of Wasatch Mountains experienced failure illustrated above.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n056
39 Front end view of the slide (p1274n030).P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n032
40 Geologic map of Bear Lake showing the geologic hazards in the area. The active Bear Lake fault zone is outlined in yellow, and landslides in red. Hazardous areas must be given due consideration by planning authorities.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n097
41 Ground subsidence leaves this fireplug supported above the sidewalk in downtown Salt Lake City.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n084
42 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 Collectionp1274n065
43 Hebgen Fault scarp near Cabin Creek, aftermath of the 1959 Montana earthquake. Note tilt of trees and the recovery of vegetation over the scarp in only 11 years (photo taken August 1970).P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n089
44 Hillside subdivision in landslide terrain. Terrain in background has slid in the past. Instrument for measuring ground displacement is housed in box in foreground. White rain gage sits atop instrument housing.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n063
45 House carried on mud-flow from Davis Creek, Davis County. Historic photo, 1930. Debris covered the highway to a depth of about 6 feet.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n020
46 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
47 Crack down the highway centerline, showing displacement. U.S. 6 near Colton.P1274 Environmental Geology and Geologic Hazards in Utah Photograph Collectionp1274n040
48 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
49 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
50 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
