sorted pebble and cobble gravel, gravelly sand, and silty sand deposited along inactive floodplains 1 to 3 meters (3-10 ft) above modern stream level; clasts subangular to rounded; mapped along Haight Creek and adjacent drainages in the northern part of the quadrangle where fluvial processes are generally no longer active; thickness generally less than 6 meters (20 ft).

QalpStream alluvium related to the Provo shoreline and regressive phase of Lake Bonneville (upper

Pleistocene) – Clast-supported, moderately to well-sorted pebble and cobble gravel, gravelly sand, and silty sand; deposited along inactive floodplains more than 3 meters (10 ft) above modern stream level; mapped where fluvial processes are generally no longer active; exposed thickness less than 6 meters (20 ft).

Liquefaction-induced landslide deposits (Holocene) – Mixture of silt, fine sand, and minor gravel redeposited in flow slides and lateral spreads (the northern part of the Farmington Siding landslide complex) as a result of liquefaction during large earthquakes; deposits display landslide-related lineaments, scarps, and hummocky topography; disrupted bedding and sand-filled cracks (injection features) are present in the deposits in the subsurface (Hylland and Lowe, 1998; Harty and Lowe, 2003); thickness generally less than 22 meters (70 ft). Most recent movement between 2700 and 4500 cal yr B.P.

Older liquefaction-induced landslide deposits (lower Holocene to upper Pleistocene) – Mixture of silt, fine sand, and minor gravel redeposited in flow slides and lateral spreads (the southern part of the Farmington Siding landslide complex) as a result of liquefaction during large earthquakes; deposits display landslide-related lineaments, scarps, and hummocky topography that are more subdued than similar features found in the northern part of the landslide complex (Hylland and Lowe, 1998; Harty and Lowe, 2003); thickness less than 22 meters (70 ft). Most recent movement between 11,500 and 13,000 cal yr B.P.

1All calibrations made using OxCal 14C calibration and analysis software (version 4.3.2; Bronk Ramsey, 2009; using the IntCal13 calibration curve ofReimer and others, 2013), rounded to the nearest 500 years.2 Oviatt and others (1990)3The Stansbury shoreline formed at elevations of about 4440 to 4450 feet (1350–1360 m), which are present in the quadrangle, but the shoreline was either weakly developed or poorly preserved and cannot be identified.4Oviatt (2015), Miller (2016), and references therein5Godsey and others (2005, 2011), Oviatt (2015), Miller (2016) for the timing of the occupation of the Provo shoreline and subsequent regression of Lake Bonneville to near Great Salt Lake level. Alternatively, data in Godsey and others (2005) may suggest that regression began earlier, shortly after 16.5 cal ka (see sample Beta-153158, with an age of 13,660 ± 50 14C yr B.P. [16.5 cal ka] from 1.5 m below the Provo shoreline). Also, lacustrine carbonate deposits in caves reported by McGee and others (2012) seem to support an earlier Lake Bonneville regression beginning around 16.4 cal ka.6Gilbert-episode highstand may have been very short lived; age represents lake culmination (Oviatt and others, 2005; Oviatt, 2014).7Murchison (1989), Currey and James (1982)8Miller and others (2005)9Arnow and Stephens (1990)

Rise and fall of Lake Bonneville between about 28 and 13.5 ka, and of Great Salt Lake (modified from Oviatt, 1997; Murchison and Mulvey, 2000; and Godsey and others, 2005). Elevations have been adjusted to remove effects of isostatic rebound. Holocene portion of hydrograph is largely schematic.
