Summary

This held NOAA chart is the 1931 Beaver Island Group Including North Shore of Lake Michigan from Waugoshance Point to Seul Choix Point nautical chart (LS79), at catalog scale 1:80,000. It provides a primary navigational-map snapshot of the archipelago and adjacent north Lake Michigan shore.

Evidence and limits

The NOAA catalog and provenance establish the chart’s title, chart number, year, type, scale, coverage, and held image. The chart is a navigational source from 1931, not a present-day navigation aid or a complete record of ownership, settlement, traffic, light operation, or every feature shown on the sheet.

Individual soundings, symbols, notices, and aids to navigation should be read directly from the full-resolution image and cross-checked against the chart’s own revision information before being turned into separate factual claims.
