The #glacier went that-a-way
The #striations on this face of the #Ediacaran (ca. 560 Ma) #Squantum Member of the #Roxbury #Conglomerate were probably left by the #Pleistocene #Laurentide ice sheet, which retreated ca. 12 ka. The striations have the right orientation, from northwest to southeast.
The Squantum Member was once interpreted as a (#glacial) #tillite. The most common contemporary model is a peri-#Gondwana #debrite (#turbidite).

I am fascinated by #rock in all forms, the #texture, #pattern, color, design and #striations and this striking, #rocky shoreline with terrific water #reflections was a thrilling discovery on the #KeyRiver #Ontario Canada. This is one of my favorite captures with not only the beautiful detailed rock but the #reflection as well.
