Arches National Park

Today it was arches, hoodoos and a lizard. Perhaps because it was Saturday but many of the lookouts were crowded so in at least one case we missed a walk to a view point for a couple of significant arches. What we did see was stunning. I wonder though where are all the medium and small rocks. There are large/huge rocks and sand, little or no gravel/pebbles. Missed the picture of the lizard. I'll let the pictures tell the rest of the story.
