2008 - Swirly Rock, Soudan, MN

Located on the grounds of Soudan Underground Mine State Park, in Soudan, MN, an unbelievably gorgeous geological formation that local geocachers have dubbed Swirly Rock.  I would love to hear from anyone that can explain the layering of stone in this rock formation.

Enjoy the photographs (click thumbnails for larger view)..
