...Aaron D. Melody; Beau B. Whitney; Christopher G. Slack Abstract Evidence for active faulting in the Truckee Basin, north of Lake Tahoe, is observed in a meadow containing a scarp and small closed depression. Shallow, hand‐dug trenches show offset marsh stratigraphy of Holocene age...

...WILLIAM C. B. GATES; ROBERT J. WATTERS Abstract Reno, situated within the Truckee Meadows, just a few miles east of the California state line, is located between two markedly different physiographic provinces. One province is the Sierra Nevada (to the west), a region characterized with high...

... tectonic region. Two high‐angle, left‐lateral strike‐slip earthquakes ( M w 3.65 foreshock and M w 3.85 mainshock), occurred 7 min apart, ∼ 20 km north of Truckee, California, on 27 June 2017. Both events were felt over a wide area in northeastern California and northwestern Nevada and happened nearby...

...Lewis E. Hunter; Ronn S. Rose; Bruce Hilton; William McCormick; Todd Crampton Abstract Martis Creek Dam, located in the Truckee Basin north of Lake Tahoe, CA, was initially rated as one of the U.S. Army Corps of Engineers’ highest risk dams in the United States. While the dam has performed its...

...Kenneth D. Adams Abstract The Truckee River in western Nevada has severely incised in response to a net 20 m of lake-level lowering of Pyramid Lake over the past 120 yr, leaving a suite of cut terraces that extend ∼15 km upstream from the lake where incision was arrested by bedrock in the channel...

... Dam near Truckee, California. Bare-earth LiDAR imagery reveals a previously unrecognized and apparently youthful right-lateral strike-slip fault that exhibits laterally continuous tectonic geomorphic features over a 35-km-long zone. If these interpretations are correct, the fault, herein named...

... yield detailed geologic structure that is consistent with this hydrologic connection. This article presents details relating to characterization of the alluvial basins in the southern Truckee Meadows south of Reno and important findings related to the adjacent geothermal system at Steamboat Hills...

...EARL M. P LOVEJOY Abstract Truckee River crosses northern Carson Range in a gorge 3000 ft deep, passing east from Truckee Valley, elevation 6400 ft, to Truckee Meadows, elevation 4400 ft. A suggested nonantecedent origin for this gorge is based on headward erosion in the easily eroded pyroclastic...

...Yi-Ben Tsai; Keiiti Aki abstract With additional data on P wave polarities, the existing fault plane solution for the Truckee, California, earthquake of September 12 1966 (Ryall, Van Wormer and Jones, 1968) is revised to have the following strike and dip angles for its nodal planes: Strike Dip...

...Roger Greensfelder Abstract On September 12, 1966, at 16 h 41 m , an earthquake of magnitude 6.0 to 6.5 occurred about 10 km northeast of Truckee, California. Hypocenters of 158 after-shocks that occurred between September 14 and 25 were found to be within a volume 3 km wide by 10 km long by 12 km...

...Alan Ryall; J. D. VanWormer; Austin E. Jones abstract During an earthquake sequence near Truckee, California, in September 1966, several thousand aftershocks were tape-recorded on a small, tripartite seismic array. Using playbacks of these recordings, together with seismograms from three nearby...

...PETER W BIRKELAND Abstract In Truckee River glacial outwash deposits of the Tahoe Glaciation, boulders and gravel bars indicate discharges and velocities far greater than those of the present river. Collapse of unstable glacier dams near Lake Tahoe's outlet would have been necessary to release...

...PETER W BIRKELAND Abstract Pleistocene latite and basalt flows crop out along the Upper Truckee Canyon, located immediately downstream from Lake Tahoe, and throughout the Truckee Basin, an intermontane basin at the north end of the canyon. They were extruded over a topography somewhat similar...

... Pleistocene episodes when lava erupted subaerially and flowed into Proto-Tahoe. Three cycles of canyon damming by lava and down-cutting occurred at the outlet of Proto-Tahoe in the Truckee River Canyon. The canyon was dammed at 2.3 Ma by basaltic lavas at Rampart, which raised lake level from ∼1897 m above...

...STEPHEN M BORN; DALE F RITTER Abstract The Truckee River rises high in the Sierra Mountains and ends 30 mi (48 km) northeast of Reno, Nevada, where it empties into Pyramid Lake, the largest remnant of Pleistocene Lake Lahontan. Since 1910, the level of Pyramid Lake has declined 80 ft (24 m) due...
