...LAWRENCE C ROWAN; PAUL A MUELLER Abstract Two cross-cutting mafic dikes in the headwall of Gardner Lake in the eastern Beartooth Mountains, Wyoming, have structural relations with Archean migmatite and gneiss that suggest intrusion between deformational phases recognized in the eastern part...

...RAE L HARRIS, JR. Abstract The Gardner Lake area is one of the key areas being studied in detail in the Beartooth Mountains, Montana and Wyoming. Foliation, compositional banding, and rock units indicate open southward-plunging folds traceable through metasediments and migmatites into granitic...

.... Presence of this pervasive fold system in heterogeneous migmatites and gneisses raises the question of whether the rocks had an intrusive or metasomatic origin. Independent studies of folds and fabric in the nearby Gardner Lake area by Harris, the Southern Beartooth Mountains area by Wise, the Line Creek...

... backwash was briefly equivalent to more than 15 Squamish Rivers in full flood and would have decimated life in low-lying areas of the Tahoe region. The Lake Tahoe region has been studied extensively since the early geologic mapping of the region by Lindgren (1896) . In this summary, we concentrate...

... by it, and later were removed across a wide area by erosion. The Claron Formation and the overlying laccolith dip eastward into the Hurricane fault as part of the reverse drag along the western, downthrown block ( Gardner, 1941 ; Cook, 1957 , Figs. 10, 14). Although Kurie (1966 , PI. 1, cross sections) indicated...

... lines), position of profiles (shown below), and scuba dives (crosses). The detailed multibeam bathymetric map (surveyed in April 1998; Gardner et al., 1999 , 2000 ) depicts the bottom features of Lake Tahoe in detail, including the giant McKinney Bay landslide (debris avalanche), in which...

A CD-ROM with the images and gridded data ( Dartnell and Gardner, 1999 ) and a paper copy of the colored bathymetry ( Gardner et al., 1999...

... by draining of matrix-facies material from the distal end and burial of blocks in the proximal area. An increase in block size with distance also was reported for the subaqueous McKinney Bay debris-avalanche deposit in Lake Tahoe ( Gardner et al., 2000a ). Blocks in the Chaski Bay debris avalanche apparently...

... for different seismotectonic conditions can give different results. In this article, we analyze the efficacy of several declustering algorithms in study seismicity in the Tauro Caucasus region and their influence on seismic hazard assessment. We examine approaches proposed by Gardner and Knopoff (1974...

... in terms of its depositional environment (submarine fan) and tectonic setting (structurally confined basin). Higgs interprets the Ross Sandstone as being deposited in a large, shallow, freshwater equatorial lake located in a broad foreland basin. He uses this interpretation to argue that the Ross Sandstone...

Gardner and Dekens (light red) received 57 citations for their article on mountain hazards in India and Canada, which was published in the Natural Hazards journal...

... identified in Lake Tahoe, and examination of their source areas suggests they originated from different initiation points along the steep margin, with some being synchronous around the basin, as opposed to flood-related deposits. Lithologic characteristics, magnetic susceptibility, carbon and nitrogen...

... routes. The current model for magmatism at Mount Hood is one of recharge filtering (Kent et al., 2010). This model envisions two end members: a mafic recharge magma and a silicic filter (or mush) stored in shallow crust (Scott and Gardner, 2017). These two magmas interact in the weeks to months prior...

... and destruction of the late Miocene lake systems as defined by Faulds et al. (2016) . Identification of a younger, late Pliocene lake system indicates that Lake Nellis lingered after establishment of the Colorado River system in this area (5.6–4.9 Ma; Faulds et al. 2016 ) and also lingered after the younger...
