Although the Alta snowcat skiers have names for all of the runs on the north side of Grizzly Gulch, the name Michigan City is usually applied to all of the runs on the north side of Grizzly that are west of Black Bess (i.e., from the "Grizzly Cup Area" through the "Freeland Area").
The name comes from the Michigan-Utah mine which was active from 1901 through 1919. The mine's entrance was on the lower portion of this slope (a little above the flats). It primarily produced silver and lead. See the discussion of the Alta Ski Resort for more information on the history of mining in upper Little Cottonwood Canyon.
Originally, backcountry skiers used the name Michigan City only to refer to the flat area in Grizzly Gulch. The name is now commonly used to refer to all of the terrain on the north side of Grizzly Gulch that is above the flat area.
