The Fine Print

DATES:   This trip is offered every 3 years, next one will be in 2018.  To get on our waitlist, email us with the subject "Rockin Wyoming".

Accommodations are in mid-range motels, mostly Best Westerns. You can stay with the group, or choose another motel or camp nearby. Each evening Bob will present an evening program (you are welcome to attend whether you stay with the group or not).

Because of the distance traveled, the trip can be started in several places.

  • Day one, departs Seattle, ends in Pendleton, OR.
  • Day two, Pendleton to Twin Falls, ID.
  • Day three, Twin Falls to Kemmerer, WY.
  • Day four and five we’ll drive about 20 miles to the quarries near Kemmerer.


  • 5 day trip (Seattle to Kemmerer): $490/adult, $390/child
  • 4 day trip (Pendleton to Kemmerer): $390/adult, $290/child
  • 2 day trip (meet us north of Salt Lake City or in Kemmerer): $300/adult, $200/child


Guide(s), instruction, programs, access to private localities, tools. Book your own lodging. We have reserved 10 rooms at each motel, at a discounted price. Just tell the reservation person that you are with Geology Adventures to receive our discount.

Minimum recommended age: 6 years, due to attention span. We've met 4 year olds who would love this trip, but parents are cautioned that kids will not be permitted to randomly hammer rocks (ie: destroy fossils) in the quarries. The fossil collecting tools we supply (mason’s hammers, chisels, and spreaders) are sharp; definitely not toys. We can provide 2 lb. sledge hammers and less sharp chisels for kids, just let us know when you book.


  • Road food: at least snacks & lunches, as the collecting localities are away from civilization. The rural towns in which we stay have a normal assortment of restaurants, fast food, and grocery stores.
  • Safety glasses: we have one-size-fits-all goggles, but you’ll be far more comfortable in a pair of your own. Kids are required to wear safety goggles/glasses if they use our tools. We recommend eye protection for adults.
  • Vehicle in good repair: most of our drive will be on pavement, but we will drive about 20 miles on gravel or dirt roads each day. You will not need 4WD.
  • Water bottles, sunglasses, sunhat, sunscreen, daypack, at least one sturdy box or Rubbermaid tub and newspaper for your fish fossils, plus buckets or boxes to keep your other rocks from rolling around your vehicle.
  • Layered clothing. Wyoming is high desert. June is usually very comfortable, but can be quite hot or cold. Daytime tems can range from 30's to 80's ... usually 60 to 70.
  • Sturdy shoes. Running shoes are ok, but you’re feet will thank you for putting something heavier between them and sharp rocks.
  • Work gloves.


  • Best Western, Pendleton, OR. June 27 (541) 276-2135
  • Best Western, Twin Falls, ID. June 28 (208) 736-8000
  • Best Western Fossil Inn, Kemmerer, Wy. June 29 & 30 (307) 877-3388
  • Bob usually offers a bonus day at a nearby locality.  If you'd like to stay for that (free) day, book an extra nite's lodging in Kemmerer.

The fine print:

99% of the fish in these quarries are common species: Knightea, Priscacara, Diplomystus, Phareodus, Mioplosus, Amphiplaga, etc. You’ll find beautiful and scientifically interesting specimens, which we’ll teach you how to identify and prepare. If you (or us guides) find something rare, it belongs to the quarry owner. They MAY be willing to sell it to you once it has been professionally prepared. The quarry owners are under obligation to the state of Wyoming, from whom they lease their land, to preserve for science any exceptionally rare species. Rare species which you would not likely be able to keep (unless you write a large check!) are turtles, birds, mammals, sting rays, and crustaceans. Good info on what you’re likely to find is: here.
