Denali National Park Denali National Park protects a large expanse of subarctic wilderness shaped by tectonic uplift and glacial erosion. Denali, the tallest peak in North America, rises dramatically above surrounding tundra and forest environments. The park illustrates the geological forces that created the Alaska Range and continue to influence the landscape today. Glacial valleys, […]
Wrangell–St. Elias National Park Wrangell–St. Elias National Park preserves one of the largest protected mountain landscapes in the world, encompassing vast ice fields, active volcanoes, alpine tundra, and extensive river systems shaped by tectonic uplift along the boundary of the Pacific and North American plates. The park lies at the convergence of several major mountain […]
John Day Fossil Beds National Monument John Day Fossil Beds National Monument protects sedimentary layers that preserve fossils documenting environmental change over tens of millions of years. Fossilized plants and animals illustrate transitions in climate and ecosystem conditions that influenced the development of landscapes across the Pacific Northwest. Colorful rock formations within the monument reflect […]
Lassen Volcanic National Park Lassen Volcanic National Park protects a diverse volcanic environment shaped by eruptions, tectonic activity, and geothermal processes. The park contains multiple types of volcanoes, including lava domes, cinder cones, and shield volcanoes, illustrating the range of volcanic activity that has occurred in the Cascade Range. Evidence of past eruptions remains visible […]
Crater Lake National Park Crater Lake National Park protects a volcanic landscape formed by the eruption and collapse of Mount Mazama approximately 7,700 years ago. The resulting caldera gradually filled with rain and snowmelt, creating one of the deepest lakes in North America. The lake’s intense blue color reflects both depth and exceptional water clarity. […]
Redwood National Park Redwood National Park preserves old-growth coastal forests dominated by coast redwoods, the tallest tree species in the world. These forests represent ecosystems that have developed over centuries, supported by a combination of coastal climate, frequent fog, and stable environmental conditions. The scale of the trees creates a landscape that emphasizes both vertical […]
Sequoia National Park Sequoia National Park is located in California’s southern Sierra Nevada, where high elevation forests support giant sequoia trees among the largest living organisms on Earth. These forests grow in a narrow elevational range where snowpack, soil composition, and climate conditions support long-lived conifer ecosystems characteristic of the western United States. The park […]
Okefenokee National Wildlife Refuge Okefenokee National Wildlife Refuge preserves one of the largest intact freshwater wetland ecosystems in North America, located along the Georgia–Florida border within a broad, shallow basin formed over thousands of years. The swamp contains peat deposits, cypress forests, open prairies, and slow-moving waterways that create a distinctive landscape shaped by water […]
Castillo de San Marcos & Fort Matanzas (St. Augustine) St. Augustine preserves one of the earliest European-established settlements in the continental United States, reflecting the strategic importance of Florida’s Atlantic coastline within Spanish colonial networks. Positioned along protected waterways connecting the Atlantic Ocean to inland environments, the settlement developed as part of a broader system […]
Dry Tortugas National Park Dry Tortugas National Park preserves a remote maritime landscape located at the western edge of the Florida Keys, where open water, coral reefs, and small islands form part of the broader Gulf of Mexico ecosystem. The park’s isolated setting reflects its historical role as both a navigational reference point and a […]
