100

This Wyoming park features mountains rising over 7,000 feet above the valley floor with no foothills.  

Grand Teton National Park

100

This stage of mountain building involves thick sedimentary or volcanic deposition.  

Accumulation Stage

100

This fold arches upward and contains the oldest rocks at its center.  

Anticline

100

This Cenozoic orogeny uplifted the Tetons and much of the Rockies.  

Laramide Orogeny

100

These crystalline metamorphic structures form the cores of many Basin and Range mountains.  

Metamorphic Core Complexes

200

This Nevada park contains Wheeler Peak and sits in the Basin and Range Province.  

Great Basin National Park

200

This active mountain‑building stage involves folding and faulting.  

Orogenic Stage

200

This fold dips downward like a trough and contains the youngest rocks at its center.

Syncline

200

This type of mountain structure dominates the Tetons, with 30,000 feet of displacement.  

Fault‑Block Mountain

200

This rounded‑boulder weathering process shaped Joshua Tree’s granite outcrops.  

Spheroidal Weathering

300

This California desert park is known for its namesake trees and filming locations.  

Joshua Tree National Park

300

This final stage involves crustal extension, block faulting, and uplift.  

Crustal Extension and Block Faulting Stage

300

This fault type occurs when the hanging wall moves down due to tension.  

Normal Fault

300

This sharp peak in the Tetons is a classic horn carved by glaciers.  

Grand Teton Peak

300

This French‑named mixture of deep‑ocean sediments and mafic lava forms Redwood’s terrane.  

Mélange

400

 This park contains the lowest point in North America at 282 feet below sea level.  

Death Valley National Park

400

This stable interior of a continent contains the oldest rocks.  

The Craton

400

This fault type involves lateral movement, such as along the San Andreas Fault.  

Strike‑Slip Fault

400

These sediment‑rich features form where streams exit steep mountains into flat basins.  

Alluvial Fans


400

These tallest trees on Earth grow in the foggy coastal ranges of northern California.  

Coast Redwoods

500

These two adjacent California parks contain Mt. Whitney and the world’s largest trees.

Sequoia and Kings Canyon National Parks


500

This process adds exotic terranes to continents, such as in California and Oregon.

Tectonic Accretion

500

This mining‑derived term refers to the rock above a dipping fault plane.  

Hanging Wall

500

This term describes the Great Basin’s lack of any surface drainage to the ocean.  

Internal Drainage

500

This Arkansas park is the smallest national park and features 47 thermal springs.

Hot Springs National Park
