We were able to find some awesome specimens of conglomerate rock during our trip to Oregon. Actually, my son found the one in the button above and my husband found the one below. I told them what I was looking for and I was shocked they found two so very different from each other.
This is our fourth official rock from the list which we pulled from the book Rocks, Fossils and Arrowheads (Take-Along Guides). (Affiliate Link)
Conglomerate rock is a sedimentary rock that contains large rounded particles. The rock particles are stuck together with sand that filled in the spaces. There can be many different colors of conglomerate rock depending on the color of the gravel and sand where the rock was formed. Colorful conglomerates may be called "puddingstones".
You can look for conglomerates in rivers, ocean beaches, or even in dry rocky desert areas where there used to be water.
