This improved mapping of the WTDPF reveals the fault geometry and architecture south of Lake Tahoe and improves the geohazard assessment of the region. The Cascade Lake data combined with onshore Lidar allow us to map the WTDPF continuously between Fallen Leaf Lake and Cascade Lake. In addition, Chirp data beneath Cascade Lake image strands of the WTDPF offsetting the lake floor as much as ∼7.5 m. for large earthquakes on the Fallen Leaf Lake segment of the WTDPF, and the time since the most recent event (∼4.5 k.y. If this correlation is correct, we postulate a recurrence interval of ∼3–4 k.y. The temporal correlation of slides between multiple basins suggests triggering by earthquakes on the WTDPF system. Slide deposits imaged beneath Fallen Leaf Lake appear to be synchronous with slides in Lake Tahoe, Emerald Bay, and Cascade Lake. Here we present results from high-resolution seismic Chirp (compressed high intensity radar pulse) surveys in Fallen Leaf Lake and Cascade Lake, multibeam bathymetry coverage of Fallen Leaf Lake, onshore Lidar (light detection and ranging) data for the southern Lake Tahoe Basin, and radiocarbon dates from piston cores in Fallen Leaf Lake and Emerald Bay.
Fallen Leaf Lake, Cascade Lake, and Emerald Bay are three subbasins of the Lake Tahoe Basin, located south of Lake Tahoe, and provide an opportunity to image primary earthquake deformation along the WTDPF and associated landslide deposits. Wag! does not allow or encourage Pet Care Providers to bring dogs to parks.The West Tahoe–Dollar Point fault (WTDPF) extends along the western margin of the Lake Tahoe Basin (northern Sierra Nevada, western United States) and is characterized as its most hazardous fault. The trail is one of the best places to see aspens in the fall and provides a great backdrop to enjoy your time with your pooch. It is also wise to bring clean up bags, water and snacks for yourself and your doggie. There are a few dog rules that you will need to observe, including ensuring that you pick up after your barker, and that your pooch is always on a leash. There is also the Fallen Leaf Store and Marina that serves food for lunch from Memorial Day through October 1st, so grab some grub for you and the pup if hiking then. There are also several amenities including restrooms, a covered picnic shelter, and picnic tables. Some of the other activities that can be enjoyed along the trail include dog-friendly biking, picnicking, fishing, and swimming. However, you will need a SNO-Park permit to participate. In winter, the trail offers cross-country skiing and snowshoeing. The Fallen Leaf Lake Trail has a lot to offer visitors, including a wide variety of sporting activities all year round. It is well worth the adventure to explore the different trails and find your way around if you have some time on your hands. Parking is available on the shoulders.įallen Leaf Lake Trail is generally flat and runs right along the lake’s shoreline, which is about 15 minutes in to the hike. Note that the main trail juts out into several smaller trails, so bring a map with you to stay on course. Then follow the road past the campground to the Fallen Leaf Lake Trailhead. More specifically, to access the trailhead, drive north on Highway 89 and turn left on Fallen Leaf Lake Road. The trail is also dog-friendly and easily accessible through a parking lot that is just off Highway 89. Fallen Leaf Lake Trail loops about eight miles around a picturesque landscape that features the beautiful Fallen Leaf Lake which is the second-largest body of water in the Tahoe Basin.
