Summary
This raster dataset describes elevation values, in meters (m), in Sleeping Bear Dunes National Lakeshore in 1977. The 1977 DEM was produced from historical aerial imagery acquired on April 30, 1977 at a flying height of 8,500 ft (1:17,000). Structure from motion (SfM) analysis of this imagery produced a 0.89 m DEM, which was edited and resampled to 1 m.

Purpose
This dataset was created as part of a NRPP project to map landslides and other mass movements throughout Sleeping Bear Dunes National Lakeshore. The project aims to address the potential hazards and geomorphic consequences of historic high water levels in Lake Michigan, due to active wave erosion affecting beaches, slopes, and dunes; and coastal inundation. The scale and accuracy of this dataset enable its use for local-scale analysis of dune movement, large mass movements, and terrain change due to anthropogenic activities.
