Geophysical data (geodimeter, GPS) of field activity C-1-96-MW in Sleeping Bear Point, Sleeping Bear Dunes National Lakeshore, MI from 07/23/1996 to 08/01/1996, http://walrus.wr.usgs.gov/infobank/c/c196mw/html/c-1-96-mw.meta.html. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Equipment Used - geodimeter GPS Notes - HELPING NPS UNDERSTAND LAKE MICHIGAN LANDSLIDE Bruce Jaffe recently made the news in northern Michigan, where he is studying a biglandslide that removed the beach along 500 m of shoreline in Sleeping Bear Dunes National Lakeshore in February 1995. Approximately 100,000 cubic meters of sand above the shoreline of Lake Michigan and 1,000,000 cubic meters of sand below the shoreline slid into deep water offshore, removing the beach and changing a gently sloping lake bottom into a sharp 20-m dropoff near the shore. The National Park Service, concerned about public safety and long-term effects on the coastal environment, asked the USGS to study the slide. The request presents a unique opportunity to Jaffe and his team, who conducted yearly topographic and bathymetric surveys of the area from 1989 to 1993 as part of a shoreline-change study in the Great Lakes Wetlands Project. With a detailed picture of pre-slide conditions, they are well equipped to advance our understanding of coastal and submarine landslides in lacustrine environments. The USGS team includes Rob Kayen, Ken Israel, Tom Reiss, Homa Lee, Hank Chezar, and Guy Cochrane from WUSGS and Randy Jibson from the Central Region Hazards Team. They are receiving help from Max Holden of the Park Service and Jaques Locat of Laval University, Quebec, Canada. The team has already begun conducting repeat surveys of the area, using GPS and high-precision surveying equipment to obtain elevations and positions accurate to within several centimeters. This September they plan to (1) map the slide using 100-kHz sidescan sonar, (2) conduct a bathymetric survey to quantify the volume of sediment moved during the slide, (3) map sub-bottom lake geology using high-resolution seismic reflection, and (4) deploy an underwater video camera to determine failure type and slide-plane character. In FY97 they will install instruments to measure geotechnical properties that could trigger sliding, and they will perform a slope stability analysis to help the National Park Service predict when the area may slide again. Two previous slides in this century--in 1913 and 1971- -indicate that landsliding will recur at the site. The team's work was recently featured in front-page articles in two northern Michigan newspapers, the Traverse City Record-Eagle (daily) and the Leelanau Enterprise (weekly), and in a 10-minute National Public Radio broadcast aired on local stations.
