The floodplain is relatively wide, and erosion and deposition associated with lateral migration of the river are apparent at the two study sites along the main Navarro River in lower Anderson Valley (Fig. 1) . At both “Sisters Gulch” and “Hamilton Gulch” study sites (Fig. 1) , fans...

... alluvial deposits in Buckskin Gulch are limited to short expansions and alcoves (study sites BG-B and BG-C; Fig. 3 ). The canyon continues for ∼16 km through the Paria Canyon–Vermillion Cliffs Wilderness before meeting the Paria River (elevation ∼1270m). The Paria River goes on to drain into Marble Canyon...

... with “chalky” tuffaceous clay-rich intervals and more isolated iron-stained sandstone beds. A pumice-rich interval in the Chalk Hills Formation from Sulphur Gulch in the Hog Cove Butte quadrangle ( Love et al., 2023 ; Figs. 3 and 7 ) was dated as part of this work. The interval is a light-gray, non-welded...

... a rounded hill on the east side of Pine Gulch Creek (Fig.  4a ). Southeast of the Dogtown site, he measured a row of eucalyptus trees (Fig.  3a ) that were dislocated 4.1 m (13.5 ft) in the 1906 earthquake ( Lawson, 1908 ). These trees are still standing. On the Strain Ranch he measured a southerly fence...

We can derive several conclusions from this analysis. The carnivorous Hoplocarida form a single clade. Furthermore, this analysis confirms the paraphyletic...

There is a striking transition to a 5-pored dominance (32–67%) with an accompanying increase in 6-, 7-, and even 8-pored grains in outcrops of the Sterling Formation along the Cook Inlet shore, north of Clam Gulch and at the head...

... (Table  1 ). Quartz Creek tephra (UT1053, UT1001) is interstratified with sands and silts in the upper part of the White Channel gravels (Fig.  4E ). In places, this tephra bed drapes into ice-wedge casts or is cut by them. Mosquito Gulch (UT19), Bonanza Creek (UT1055, UT1454, UT1457...

Mesquite density is considerably higher in areas at channel margins and in areas of distributary and overland flow ( Fig. 2 ). These trees rapidly colonized...

..., the move- ment on July 10, 1958, was predominantly strike-slip, and the dip-slip component, if not zero, was too small to be recognized. Evidence for the predominant strike-slip character of movement was seen at Fig. 5 (left). Old fallen tree lies beneath interlocking dead lower branches of two upright...

... southwest of the Broxson Gulch fault system. Waveform modeling ( Fig. 5 , Table 2 ), however, suggests the earthquake involved normal faulting within the subducting Pacific plate at a depth of 60 ± 15 km. The rupture zone of the 2002 sequence has been one of the most seismically quiescent portions...

An extensive area of remarkably flat to moderate topography at an average elevation of ~2,600 m, it is widest (60 km E–W) at 39 degrees north latitude west of Colorado Springs, a transect that is the focus of this paper ( Figs. 2 and 3 ). Along this transect the surface has been broken...
