Glen Rose

About 113 million years ago, during the early Cretaceous Period, Glen Rose, Texas sat along the shore of an ancient sea. Limestone, sandstone and mudstone were deposited, and in the last one million years have been eroded by the current of the Paluxy River. This erosion revealed a remarkable variety of dinosaur tracks, often so clearly imprinted that you can trace their steps through the dried riverbed. Go on a day that’s not too hot or sunny, and spend an hour or so climbing rocks and looking for footprints.
