Time Travelling Rocks


August 23rd: This picture takes a bit of explanation. The slab of rock on the shore has a bubbly surface. They are actually ancient ripple marks that run right to left, top to bottom. They were made when this rock was mud, at the bottom of a warm sea, 450 million years ago. The water beside this rock is Toronto's Mimico Creek, which is constantly eroding these time travelling rocks.
