Ann’s Musing on Geology & Other Things is hosting the Accretionary Wedge #29: What geological features about the area you call “home” do you love? and what do you not like? Its a busy time at the end of the semester, but I knew immediately how I would answer this question.
I’ve only recently moved to St. Peter in order to teach for a year at Gustavus College. Previous to Minnesota, I’ve lived in a variety of places and in my mind they all can be categorized either as “flat” or as “hilly.” The flat places I’ve landed have all been located on sedimentary rocks & have involved at least a several hour drive to reach a garnet-bearing metamorphic rock. But some of the hilly places have also been a few hours from garnet-grade rocks. My ideal “home” would have garnet-bearing rocks either underfoot or within a 30 minute drive and some form of topographic relief greater than a few 100 meters. Such as:
However, I currently live on glacial till next to a river valley that cuts down into dolomite & sandstone. Ok, the erratics have garnet in them occasionally, but that’s not the local bedrock. Things I can appreciate here, though? Its not dead flat. The till has a fairly nice hummocky topography to it.
I can also get to high grade metamorphic rocks in a few hours, which is almost close enough to drive to during a lab period. Actually, the gneisses are along the same river that flows through town, so technically I think I could canoe upriver to get to garnets. Would probably take a while to get there though…
I also appreciate the fact that I live within the listening range of Minnesota public radio that has a very diverse & eclectic selection of classical music on their playlist. But that’s the pianist in me speaking 🙂
