Landslide of bedrock onto highway; a frequent problem for highway maintenance, sometimes necessitating blasting of large bedrock blocks.

79
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.

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.
