Shaded bathymetry map of the Virgin Islands basin and the Virgin Islands platform. Blue lines indicate locations of seismic profiles shown at the bottom right corner and in Figure 10. Heavy dashed line indicates the proposed location of the fault rupture of the 1867 earthquake and tsunami. Thin dashed lines represent other possible active faults in the area. The dotted line encloses the area of morphological disturbance in the basin wall below the proposed 1867 fault rupture. The brown area at the eastern end of Vieques indicates the uplifted and tilted Pleistocene platform (Meyerhoff, 1926). The black rectangle shows the location of dive. Yellow star is the location of earthquake swarms in 1978–1979 (Frankel et al., 1980). NF, RF, and ZF are the central locations of fault sources used in the tsunami simulations. DF is the fault trace proposed by Donnelly (1965). Top right inset: dive along the proposed fault scarp by Donnelly (1965). Note that the slope is covered by well-developed lettuce corals. Photo taken by Drex Harrington. Bottom right inset: part of single-channel seismic line Ti-2 collected by a mini-sparker in 2009. Note the lack of offset along the proposed fault by Donnelly (DF). Top left inset: enlargement of the multibeam bathymetry in the region marked by an open black rectangle. LPG, location of Laguna Playa Grande where Woodruff et al. (2008) did not find distinct tsunami deposits from 1867.

Major elements of evolving late Miocene drainage networks in Lake Mead region. (A) Map view of region showing through-flowing lakes and interconnected terminal playas overlain on digital elevation model. Inferred drainage and groundwater flow paths are color coded according to individual through-flowing lakes, which are time transgressive from west to east (see Fig. 17). (B) Diagrammatic north-south cross section showing relative elevations of axial basin (southern Grand Wash Trough) and neighboring deeper basins (northern Grand Wash Trough and Hualapai basin), which collectively comprised Lake Grand Wash ca. 12–7.5 Ma. An early intermediate lake and/or playa in the southern Grand Wash Trough evolved into a through-flowing lake, with surface and groundwater probably spilling and infiltrating into the deeper terminal basins of the northern Grand Wash Trough and Hualapai basin, where thick evaporite sequences accumulated (mainly halite and gypsum-anhydrite). (C) Schematic east-west cross section of axial basins, each containing terminal playas that evolved into through-flowing lakes sequentially from east to west. Maximum elevations of lakes are shown in cross section. Colored lines above the cross section show lateral extent of each lake, with solid lines denoting the central part of the lake and dashed lines corresponding to that portion of the lake that presumably backed up into the older lake basins. Early evaporite sequences (mainly gypsum with possibly minor halite) were followed by lacustrine carbonate deposition in these axial basins. 87Sr/86Sr ratios in the Hualapai Limestone indicate primarily groundwater sources for Lakes Grand Wash and Hualapai, whereas limestone deposited in Lake Las Vegas resembles the Bouse Formation and Colorado River water. Color scheme for major rock types shown in cross sections is the same as that in Figure 16.

Pedal stride length versus animal size. A) Comparison of stride lengths of American crocodiles high walking on land (Farlow et al. 2018) with stride and possible “pseudo-stride” lengths estimated from the pedal footfall pattern of the bottom-walking crocodile (possibly one of the same animals whose trackway was observed on land). Data cases are individual measurements of strides for each animal. Total length of the bottom-walking and swimming crocodile was estimated by its size relative to nearby fishes of known length. Total lengths of the trackmakers on land estimated from equations relating pes length to total length in Farlow et al. 2018, tables 5 and 6). Nearly all stride and possible pseudo-stride lengths of the bottom-walking crocodile were substantially longer than those of crocodiles on land. B–D) Pes stride length versus measures of trackmaker size in Recent and fossil crocodylian and crocodylomorph trackways. Where more than one stride or measure of footprint size could be determined in a trackway, values are means for that trackway; views: B = Pes stride length versus known or estimated animal total length. For the Playa Grande bottom-walking crocodile, mean pes stride length is based on strides LP0-LP1, RP0-RP1, and LP3-LP4 (i.e., excluding possible pseudo-strides and/or intervals where the crocodile was being swept along by waves); C = Stride versus pes print length (modified from Farlow et al. 2018, fig. 28C); D = Stride versus pes print width. Data from Bennett (1992), Moratalla et al. (1995), Fuentes Vidarte and Calvo (2001), Mazin et al. (2003), McCrea et al. (2004), Erickson (2005), Pascual Arribas et al. (2005), Avanzini et al.

(A) Reconstructed topography of the original 10 Ma surface produced by removing isostatic rebound from the surface in Figure 3 (UTM—Universal Transverse Mercator; Elev.—elevation). This is equivalent to adding the eroded thickness in Figure 4 to modern topography, and applying the isostatic subsidence that would result from the new load. If no tectonic uplift has occurred in the past 10 Ma, this would be the elevation of the paleosurface at 10 Ma. Noted features: Basin and Range (B&amp;R); Kaibab Plateau (KP); Bidahochi Formation, Hopi Lake (B); Canyonlands (CL); Browns Park (BP); Green River Basin (GRB); southern Rocky Mountains (SRM); Rio Grande Rift (RGR); eastern piedmont of the Rocky Mountains (P). (B) Speculative drainage patterns on the 10 Ma paleosurface. Although fragmentary, available information on the 10 Ma river drainage network would have the Colorado River flowing across the Grand Mesa (GM) at an elevation of 2200 m, joining the Gunnison River, and flowing across the buried Uncompahgre uplift (U) into playa lakes on the Colorado Plateau at 2000 m elevation, but with no outlet through modern Grand Canyon. Hopi Lake (B), Muddy Creek basin (MC), the Rio Grande Rift (RGR), and Browns Park (BP) were probably internally drained. The continental divide was in a similar position to today, and the ancestral Rio Grande was south flowing off the southern Rocky Mountains into playa lakes in the Rio Grande Rift, but not yet integrated to the Gulf of Mexico. Other noted features are: Kaibab uplift (KU); Monument uplift (MU); proto–Lake Bonneville (LB); Alamosa Lake (A).
