Like an enormous tidal wave, a shelf cloud hundreds of feet high extends out of sight as it sweeps ashore. I have an eye-level view of the fast-approaching front from the observation platform built atop a 450-foot-high dune bluff on the Lake Michigan shoreline at Sleeping Bear Dunes National Lakeshore.
