It was a short drive over to Sunrise, just outside Hartville, Wyoming.  This was the primary reason for the trip.  We were able to learn a lot about this special red-ochre and stone source, about the history of iron mining in eastern Wyoming, visiting with colleagues and meeting new people with common interests.  I had co-ordinated the planning of this event with George and Geri Zeimens.  Unlike Hell Gap the main mission was to gain insight into a special source of stone that is found in conjunction with the iron ore deposits and archaeological site.  The property is privately owned and accessible only through permission of the owner. For a western mine Sunrise has a long and interesting history (see wikipedia article)  Here is an extract from this article with some images from our visit.  "Colorado Fuel and Iron hoped to make Sunrise a model company town. In the early 1900s company-owned houses, boarding houses, depots, a school, churches, shops, and other structures were built. In response to the Ludlow Massacre, further improvements came to the town in the 1910s and 1920s in the form of better brick housing, a YMCA building, parks, a playground, better utility systems, a hospital, and other improvements."  "The district was added to the National Register of Historic Places in 2005."  Quite a few buildings in various stages of disrepair.  It would be a bird watchers paradise.
