The Salt Lake City North 7.5' quadrangle includes the downtown area of Salt Lake City to North Salt Lake and west to the Salt Lake City International Airport. The Warm Springs fault of the Salt Lake City segment of the Wasatch fault zone separates the valley floor from the exposed Cambrian to Tertiary bedrock in the Salt Lake salient. The unconsolidated surficial deposits exposed in the quadrangle are mostly alluvial stream deposits related to the Jordan River and its tributaries and lacustrine and deltaic deposits. Lacustrine and deltaic sediments were deposited in Late Pleistocene-age Lake Bonneville (30 to 13 ka), the Gilbert-episode lake (~11.5 ka), and Holocene Great Salt Lake (since ~13 ka). Bedrock in the quadrangle include southeast-dipping Paleozoic rocks overlain unconformably by Tertiary strata. Tertiary tuffaceous strata is prone to landsliding with numerous historical landslides in the City of North Salt Lake and City Creek Canyon.
