Much to most people’s surprise, Lake Superior’s north shore has a volcanic past and one of the after effects of the intense heat is cracks filled with mineralized gases. The cracks come in many sizes, some hairline, some several inches wide. There are many places you can find long and wide bands of quartz running through the rocks. Agates are also abundant. The cracks in these images are of the hairline variety and with the effects of water and the surrounding rock surface, nature has created and almost alien landscape.
