Okay, Pretty Much Every Single "Fact" Is a Mistake

but the pictures at Dark Roasted Blend today are very nice, nevertheless.First, I wouldn't call those striations; the bedding is being clarified as the result of differential weathering and erosion. Second, striations (meaning scratches) are not necessarily caused by glaciers, wind or waves. Third, these canyons are not "fed by the Colorado River." They're tributaries of that river, meaning they flow into it, not vice-versa.

Still, the photos are awfully pretty.
