Description:

Abstract:

This cover contains the point locations where landslides covered or came close to the tracks of the Burlington Northern Santa Fe (BNSF) Railway between Seattle and Everett, Wash., during the winters of 1996 and 1997. Employees of BNSF or its consultant, Shannon and Wilson, Inc. estimated the locations by railroad mile post.

Purpose:

This cover shows the distribution of the recent landslide activity along the bluffs next to Puget Sound between Shilshole Bay and Everett, Wash. The data are not intended to be used at any finer scale than 1:24,000. The data should not be used as a substitute for detailed investigation to determine site-specific slope stability or the existence of landslides at specific sites.

Supplemental_Information:

The coverage combines data from the U.S. Geological Survey and Shannon and Wilson, Inc. Data provided by Shannon and Wilson, Inc. are used with permission of Burlington Northern Santa Fe Railroad.
