The free Bryce field guide

Explore Bryce

A rim with many perspectives.

Start above the amphitheater, where ridges and gullies show how the plateau is being worn back. Then compare that broad view with a single formation. The atlas places the landscape stories in their geographic setting.

Read the model, and its limits

These are derived landscapes, not current conditions. Elevation, imagery, drawn surfaces and inferred shapes have different dates and levels of detail. They help explain the land; they do not determine whether a trail is passable.

A 35-minute Bryce Canyon geology lesson

Open the printable bundle →

Learning question: what breaks rock down, and what carries the pieces away? Learners practice distinguishing weathering from erosion, holding variables steady in a comparison, and separating a model result from evidence about the park.

Prepare: paper, pencils and the three-page lesson with two learner sheets. Suggested ages 10–14 and timings are BCC editorial choices, not curriculum certification. A shared screen is optional; no account, rock collection or physical freezing experiment is needed.

1. Notice · 5 minutes

Read the plate descriptions or study the annotated hoodoo sequence. Describe the wall, opening and columns using only what is shown. Put a proposed explanation in a separate sentence.

2. Compare · 15 minutes

In Weathering Lab, choose “Water, frost & varied beds” and set Model steps to 36. Record the wall seed and settings. Choose “Take water away” while keeping the wall and step unchanged. Compare reference A with experiment B. On paper instead, predict the two cases and label the result “not tested.”

3. Trace material · 10 minutes

Identify where your explanation involves breakdown and where it requires transport. Draw an arrow for material moving away. Discuss the missing span in a window-to-column drawing without assuming every hoodoo follows the same sequence.

4. Make a bounded claim · 5 minutes

Complete: “In this model, changing ___ affected ___. My evidence is ___. This does not tell us ___.” Learners can write, dictate or point to a numbered stage while a partner records their explanation.

Teacher explanation and evidence limits

Weathering breaks down or changes rock in place; erosion transports material. In a fair model comparison, water is the changed setting while the wall, step and other settings stay fixed. Accept an accurately described result, including no visible difference; do not require a predetermined outcome. A paper prediction is not an observed result. Neither version establishes an erosion rate, the age of a real hoodoo or its stability.

The process explanation follows NPS Hoodoos and NPS Wall and Narrows. The diagrams and model are BCC teaching constructions, not field observations. Keep the credits and limitations with copies; the printable bundle identifies its source dates. Source facts do not imply NPS endorsement.

Derived model of Thor’s Hammer, showing the narrow column and broad cap.

02 / Look closer

Hoodoos: /natural rock spires/

Ridges become fins, windows open, and separated columns remain as rock wears away. Thor’s Hammer makes the contrast between cap and narrow neck easy to see.

What is measured?

The 2018 USGS airborne lidar supplies much of the shape. The aircraft could not see beneath the cap; that part is interpreted from a photograph. Surface colors and fine texture are drawn, not measured.

Methods and original sources →

03 / Along the scenic drive

A window called Natural Bridge.

Despite its name, this is an arch: weathering opened a hole through the rock rather than a stream carving a bridge. Compare the opening with the surrounding fin, then notice how much stone remains above it.

Evidence behind the opening

The model uses 2018 USGS laser data; the opening is traced from a USGS photograph taken at the overlook. It is an interpreted reconstruction, not a complete ground scan.

Queen’s Garden terrain model with a trail descending from the rim.

04 / Follow a trail

From the rim into Queen’s Garden.

A view from above turns into a walk among the formations. The model places a mapped trail on the lidar ground so you can inspect the descent and the return climb. Check the separate current trail notices before using it to plan a walk.

A much longer story.

Move through Deep Time →

Before there were cliffs

Begin with deposited sediment, then consider burial, rock formation, uplift and removal. Bryce’s modern shape is only one chapter in that longer history; a rock’s age is not the age of the hoodoo it now forms.

After the sun goes down

The night sky changes with date and time. Use the sky explorer to learn the patterns, then plan a visit with the weather and local lighting in mind. A rendered sky is a calculation, not a camera or a guarantee of visibility.

A living landscape.

Plants & wildlife field guide →

Move from rock to habitat: forests, open ground, water and darkness support different kinds of life. The field guide introduces species and their relationships to this place. It does not report real-time sightings, population estimates or sensitive nest locations.

Observe from a distance, keep wildlife wild and leave the ground and plants as you find them. The park’s current rules and closures remain the authority for your visit.
