This picto- Irial article covers the time period and brings the reader up-to-date on some of the more important finds that have been made. Crushing of mine dumps continues, and many of the mining properties have been posted by property owners due to liability concerns. Collecting also continues but at a much slower pace than in the past. Figure 3. A 4.1-mm nest of copper wires in a quartz vug, Ahmeek No. 1 mine, Ahmeek, Keweenaw County, Michigan.
