A night chart of Lake Michigan, printed 24 × 36 inches. 142 lighthouses (117 still lit, 25 dark) glow in their lamps’ true colors, each sized by how far its light carries on a clear night, alongside 319 charted shipwrecks. Every light and wreck is numbered and listed in a full index, with a legend that explains how to read marine light codes. Part of the Lighthouses & Shipwrecks series from Ridgeline Maps.
