...Figure 4. Lamb Creek debris flood of September 2004. (a) An erosional reach of Gold Hill Creek channel, showing glacial till exposed after flood has stripped away overlying sediment. (b) Debris-flood deposits lower down Gold Hill Creek channel. Photos by: Doug Nicol, BC Forest Service. ...

...Albert Prieto-Márquez; Susana Gutarra Abstract The Careless Creek Quarry (CCQ) is a multitaxic bonebed in the Campanian Judith River Formation of south-central Montana (USA) that produced a diverse assemblage of vertebrates, including several dinosaurian clades. We describe the morphology...

... of a broad knickpoint or cataract complex several km in length ( Hanson, 1970 ; Larsen and Lamb, 2016 ). Whether Wilson Creek was eroded by a prominent knickpoint is unclear, but we assume that headward incision by plucking played a role in its incision for the purpose of calculating cataract retreat rates...

... location of photos in Figure 4 . Channel flow is from east-northeast to west-southwest. To predict incision rates along White Branch Creek, we used a one-dimensional (1-D) mechanistic model of bedrock abrasion by total sediment load ( Lamb et al., 2008b ). Sediment supply has a strong influence...

... is present at or near the lithologic change at each locality. On Coal Creek near Cedar City, the change from Chinle to Dinosaur Canyon lithologic features is clearly visible, and the contact is marked by a disconformity at the top of a calcareous layer containing shale fragments. Judged by the description...

... and Dietrich, 2004 ), extensive fluting of bedrock surfaces in lower Big Tujunga Creek suggests high erosion rates within the suspension regime ( Hancock et al., 1998 ; Whipple et al., 2000 ; Hartshorn et al., 2002 ; Lamb et al., 2008a ; Scheingross et al., 2014 ). Last, the waterfalls on the main stem...

... and Jenkins, 2007 ). The BNABC disbanded for the winter and resumed their expedition from Wood End the following year. In early July of 1874, the BNABC made their way 20 miles (32 km) southwest of Wood Mountain, and entered an area of badlands on Rock (Rocky) Creek that now sits within the East Block...

... near Johnston Creek in Banff National Park ( Lambe 1916 , plate III). Gardiner (1966) referred this species to the genus Pteronisculus but Schaeffer and Mangus (1976) questioned its specific status. Although some specimens from Wapiti Lake have also been referred to the genus Pteronisculus...

...Dirk Scherler; Michael P. Lamb; Edward J. Rhodes; Jean-Philippe Avouac Abstract Fill terraces along rivers represent the legacy of aggradation periods that are most commonly attributed to climate change. In the North Fork of the San Gabriel River, an arid bedrock landscape in the San Gabriel...

... north of Lake Mead. U-Pb age spectra of detrital zircons from Miocene–Pliocene basin fill of the Muddy Creek Formation in the Virgin River depression preclude any paleo–Colorado River sand in Muddy Creek exposures but fail to show that a Miocene paleo–Colorado River never flowed into the Virgin River...

... ). Virtually all of the common major groups of theropods and ornithopods typical of the Late Cretaceous of northern North America are present. Most of the skeletal remains are found in rocks assigned to the Prince Creek Formation of the Colville Group ( Detterman et al., 1963 , 1975 ; Phillips, 1990...

.... Many of the basins in southern Nevada that contain deposits of the Muddy Creek Formation were closed fluvio-lacustrine systems during the latest Miocene and into the Pliocene. They were subsequently integrated into the regional Colorado River system. Lacustrine deposits of the Muddy Creek Formation...

...Alexander R. Beer; Michael P. Lamb Abstract River incision into bedrock drives landscape evolution and couples surface changes to climate and tectonics in uplands. Mechanistic bedrock erosion modeling has focused on plucking—the hydraulic removal of large loosened rock fragments—and on abrasion...
