What does a Junior Ranger do?

  • Discover by using your senses.
  • Find clues to ancient habitats.
  • Imagine ancient plants and animals.
  • Explore the trails, visitor center, and historic areas.
  • Observe, reflect and learn, so you can help protect this very special place.
Junior Rangers at John Day Fossil Beds explore and learn about ancient Oregon during a time when unusual animals like beardogs, giraffe-deer, and oreodonts (sheep, pig-like animals) roamed unfamiliar landscapes. Today, scientific discoveries happen right in front of you, as paleontologists unearth fossils.

How to Become a Junior Ranger

Junior Ranger activities that can be done at the park or at home.
Activities at the Park Activities at Home
hike a trail virtually explore the park trails on the website
attend a ranger-led program or talk to a ranger call or e-mail a ranger and ask a question about the park
watch the park film watch a video about the park
complete as many activities in the booklet as you can complete as many activities on this page as you can

You can work alone, with your friends, or with your family. If you want a printed copy of the Junior Ranger booklet, e-mail us! Currently, we do not offer a digital copy of the booklet.

Discovering John Day Fossil Beds

Explore! This place is a window where we can take part in a rare view into ancient Oregon. Looking through geologic and fossil records we can go back millions of years in time and find very different places than we see today.

Discover! You will discover an ancient world millions of years after dinosaurs roamed the earth. An age filled with lumbering rhinos and stalking saber-tooths.

Imagine! Today, scientific discoveries happen right in front of you, as paleontologists unearth fossils never seen by human eyes.

Safety First!
  • Hydrate: Be sure to drink lots of water while driving and hiking around John Day Fossil Beds.
  • Get Comfortable: Wear good shoes, a hat, and sunscreen.
  • Take Care: Be careful where you put your hands and feet: snakes and spiders may be resting under rocks and in holes.
  • Be Good Company: Hike with other people. If you get lost, stay in one place.

Where am I in John Day Fossil Beds National monument?

The John Day Fossil Beds are unique with one of the longest and most continuous records of evolutionary change in the world. This 14,000 acre monument includes three very different units: Clarno, Painted Hills, and Sheep Rock.

Inside the dotted circles below, stamp your Jr. Ranger booklet at each unit when you stop there, or collect all three at the visitor center!

If you are completing this booklet online, virtually explore the Clarno, Painted Hills, and Sheep Rock units by visiting their webpages, and then check off each unit.

Where did it happen on the Geologic Timeline?

In geologic time, an epoch is a measure that’s shorter than a period, which is shorter than an era. Most of the fossils found here were deposited during the Cenozoic Era. Look at the timeline. Now draw lines here connecting the epoch name to when you think it happened.
Time Era Draw a Line Connecting the Two Years
Paleocene 11,700 years ago - present day
Eocene 55.8 Ma to 33.9 Ma
Pliocene 5.33 Ma to 2.58 Ma
Miocene 23 Ma to 5.33 Ma
Oligocene 33.9 Ma to 23 Ma
Pleistocene 2.58 Ma to 11,700 years ago
Holocene 65.5 Ma to 55.8 Ma

Ma (Megaannum) is equal to one million years! Mega comes from ancient Greek and means million, the word annum comes from ancient Latin and it means year. How many years are in a Gigaanum (Ga)?

Different places in Time — find out when they were!


Read the descriptions below. Find the different eras and epochs words in the information on the park's units: (Paleocene, Eocene, Pliocene, Miocene, Oligocene, Pleistocene, and Holocene). Then determine the age range of the rocks found in each unit. The Geologic Timeline activity will help you finish this activity.

Clarno Unit

Marching across the horizon, these 200-foot-tall pillars of ancient mud tower over the landscape. The Clarno Palisades preserve the remains of an Eocene tropical rainforest filled with crocodiles, banana trees, and brontotheres. Hiking the Clarno trails you will discover real fossils that tell a story of a place much different than the one we see in today’s Holocene epoch!

Painted Hills Unit


Like no other place in Oregon, a rainbow of colors splashes across these rolling hills, telling a story of the power of erosion and revealing remains from the Eocene and Oligocene epochs. The trails through the Painted Hills will take you to places like you’ve never seen before!

Sheep Rock Unit

Places to explore! From the Blue Basin badlands to the amazing Cenozoic era fossils on display in the Thomas Condon Paleontology and Visitor Center and from the historic James Cant Ranch and orchard to the large fossil deposits spanning from the Oligocene to the Miocene epochs, the Sheep Rock Unit has something for everyone!

Assemble a Skeleton

Help put the Pogonodon Back Together!

You can either try to draw the missing bones back in place, or draw lines pointing to
where you think these bones should go.

The Past is Present… Beneath Your Feet!

Think of something that surprised you, something unexpected that you
learned today. What was it? Either write down your answer, e-mail a park ranger, tell a family member, or draw a picture.
