This beautiful home was built in the late 1800's and was home to South Dakota's first Senator. Senator Pettigrew purchased the home in 1911 and added the Museum at the back of the home in 1925. The use of quartzite was very popular and can be seen in many of the homes and building built during the same time period. The exterior of the back portion is quite unique. I am not a rock person so am unsure if what almost looks like polished petrified wood is actual a cut and polished quartzite or if it is in fact polished petrified wood. These unusual oval and round sections are placed among the more typical jagged quartzite blocks. This is something I will be investigating this coming week.
Here is a closer look at the back side of the building showing the section to which I am referring. It is in this unusual stone that I photographed the reflection of the Museum sign for the Weekend Reflections shot. This shot also shows a reflection of the trees.
