U-Dig Fossils: Find your own fossils near Delta

We had an amazing time at U-Dig fossils, and we were blown away by how easy it was to find fossils of our very own! If you have a dinosaur lover or a rockhound, you simply have to give U-Dig a try.

We are very amateur rock hunters. We checked out the Wonderstone Quarry, and we searched up our own geodes at Dugway Geode Beds. Since our boys are always collecting, examining, and throwing all kinds of rocks, we figured that they would enjoy fossil hunting, too. Boy, we were right!

Family Owned and Operated

U-Dig Fossils is in the middle of nowhere. It requires a long drive from the Wasatch Front, some of which is on a very passable, solid dirt road (any car could do it). We paired the trip with a few other adventures near Delta and made a day of it. When we arrived, we were greeted by a friendly young man. It turned out, that U-Dig is a family operation. While we were there, we met two sons and Mom and Dad, all of whom were super-helpful. We got checked in, and they took us to a good spot for finding fossils.

Learning What to Do

Our helper started by choosing a rock, which was flat, mostly smooth, and obviously layered. He showed us how to use the hammer (provided) to break the rock apart in layers. Then he showed us the different types of fossils we might encounter. All of the fossils are marine fossils from around 500 million years ago! There are a several types of trilobytes, plants, and a few other, smaller specimens.

Finding Fossils

What surprised us most was the consistency of the fossils. In nearly every rock we picked up, there was something to be found! We are convinced that everyone who visits U-Dig Fossils will be amazed at the number and ease of fossils they find! The most difficult part was trying to decide which fossils to keep, and which to leave for someone else.

Occasionally, we’d find a particularly impressive specimen. We’d all gather round with oohs and aahs, and lots of “That’s a keeper” comments. We had such a great time working together.

After we’d had our fill of fossil collecting, we took our treasures back to the top of the hill. We laid them out on the table and decided which ones were worth polishing. We had help in this from the owners. They noted which fossils would polish nicely, which we could cut or pop out of the rock, and how we might make the best examples into displays. After we’d made the decisions, they polished, cut and explained to us how we might care for some of the more delicate fossils with a toothbrush.

What to Bring

U-Dig Fossils provides hammers to break rocks and buckets to keep the fossils. You should come prepared with the following items:

  • Gloves: simple gardening gloves will work

  • Sunglasses or Safety Glasses to protect from flying rock pieces
  • Jeans/Long pants: We recommend wearing jeans to protect legs from the rocks.
  • A Bucket or Bag to take your fossils home
