Olympic National Park, Washington — Nick Hoel's awakening
Nick Hoel, a young programmer, drives to the Hoh Rainforest with his girlfriend Patricia and encounters an ancient, moss-covered Sitka spruce that fundamentally transforms his understanding of nature and time. The encounter with this primordial forest — a place that has existed for thousands of years untouched — becomes the philosophical center of his character's evolution and sparks his eventual environmental activism.
The Hoh Rainforest is one of the only temperate rainforests in North America, containing some of the oldest and largest Sitka spruce trees on the continent. The Olympic National Park was established in 1938 to preserve this unique ecosystem, protecting old-growth forests dating back thousands of years.
The Hoh Rainforest remains a major tourist attraction within Olympic National Park, accessible by the Hoh Rain Forest Road. Visitors can hike the famous Hall of Mosses trail to see ancient trees, moss-draped maples, and the temperate rainforest ecosystem Powers describes.

Southern Appalachia, Tennessee — Adam Appich's family history
Adam Appich grows up in rural Appalachia among the remnants of once-vast American chestnut forests. His father and grandfather worked with these magnificent trees before the blight devastated the species. Adam's deep connection to his family's forestry heritage and his grandfather's stories of the pre-blight chestnut forests become the emotional foundation for his later environmental crusade against destructive logging practices.
The American chestnut tree once dominated eastern North American forests, comprising up to 25% of trees in Appalachian regions. A fungal blight introduced from Asia in the early 1900s nearly drove the species to extinction by the 1950s, devastating the livelihoods of entire communities dependent on chestnut timber.
The Appalachian region continues restoration efforts to bring back American chestnuts through breeding programs. Several sites in Tennessee and neighboring states work to restore the species, and visitors can see remnants of old-growth chestnut stumps and the current hardwood forests.
California — Ray and Doug's tech world
Ray Brinkman and his twin brother Doug work in the Silicon Valley tech industry, embodying the novel's central tension between technological progress and ecological destruction. Their careers in venture capital and software development represent the extractive mindset that Powers critiques throughout the novel — the belief that nature exists as resource to be exploited for profit.
Silicon Valley emerged in the 1960s-80s as the global center of computer and semiconductor innovation, transforming from agricultural orchards into one of the world's most valuable economic regions. The tech boom created extraordinary wealth but also environmental degradation and displacement.
The San Francisco Bay Area remains the epicenter of global technology development, with companies like Apple, Google, Facebook, and Tesla headquartered here. The region has become increasingly focused on sustainability, with many tech companies pledging to carbon neutrality.

Oregon — Environmental activism hub
Portland becomes a gathering point for the novel's environmental activists, where characters coordinate their efforts against corporate logging operations. The city represents the possibility of alternative values — a place where ecological consciousness has taken root in local politics and community consciousness, contrasting sharply with the extractive capitalism Powers critiques elsewhere.
Portland has been a center of Pacific Northwest timber and logging industries since the 19th century. By the 1980s-90s, the city transformed into a hub of environmental activism and green urban planning, hosting Earth First! activists and becoming a national symbol of the spotted owl controversy and logging protests.
Portland is known as one of America's most environmentally conscious cities, with extensive parks, bike infrastructure, and environmental organizations. The city continues as a major hub for environmental activism and sustainable urban planning.

Pacific Northwest — Ancient logging grounds
The Cascadia temperate rainforests become the focal point of the novel's environmental conflict. Characters Olivia Vandergriff and others witness the industrial destruction of old-growth Douglas firs and western red cedars that have stood for over a thousand years. The clearcuts represent the irreversible loss that drives the novel's activists toward increasingly desperate forms of protest and direct action.
The Cascadia rainforests are among the most biodiverse temperate forests on Earth, containing trees over 1,000 years old. Logging has removed approximately 90% of the original old-growth forest since European settlement, with industrial clearcut logging accelerating in the 1980s-90s during the spotted owl controversy.
The remaining old-growth temperate rainforests are protected within national forests and parks, though logging continues in some areas. Conservation organizations work to preserve and restore these ancient ecosystems, and several protected areas allow public visitation.

Iowa — Maidenhair fern and agrarian history
The Iowa farmland connects to multiple characters' backstories, particularly in the novel's opening section about the chestnut blight. Characters reflect on agricultural transformation and the loss of biodiversity as industrial farming practices have replaced diverse ecosystems. The prairie and woodland remnants represent vanished ecosystems that once covered the continent.
Iowa was once covered by tallgrass prairie and mixed hardwood forests. Since European settlement, approximately 99.9% of original tallgrass prairie has been converted to agricultural use, making Iowa one of the most dramatically transformed landscapes in North America. Industrial agriculture intensified dramatically in the 20th century.
Iowa remains America's leading corn and soy producer. Conservation organizations work to restore prairie remnants and native ecosystems, and several state and national preserves protect remaining tallgrass prairie and wetlands that visitors can explore.

Chicago, Illinois — Botanical knowledge and preservation
Patricia Westerford, the novel's brilliant botanist, works in urban botanical gardens and herbaria, using scientific knowledge to understand plant communication and forest ecosystems. Her research and teaching become weapons in the novel's environmental struggle, proving that trees are far more complex and interconnected than industrial society acknowledges.
Chicago's major botanical institutions developed in the late 19th century alongside the city's growth as a major metropolis. The Chicago Botanic Garden was established in 1891 (originally as the Chicago Flower Show) and became one of America's foremost horticultural centers, housing extensive plant collections and research facilities.
The Chicago Botanic Garden remains one of the largest botanical gardens in North America, open to the public with extensive plant collections, research programs, and educational facilities. It attracts millions of visitors annually.

Multiple states — Economic backbone and ecological trauma
The Mississippi River appears as a symbol of America's transformation from natural systems to industrial infrastructure. Characters' connections to the river reflect how even the continent's most mighty natural features have been engineered, dammed, and exploited. The river's polluted state and ecological collapse underscore the novel's central tragedy.
The Mississippi River was crucial to Native American and early American economies, serving as a transportation corridor for commerce. Industrial development transformed it into a shipping superhighway, with dams, locks, levees, and tributary damming fundamentally altering its hydrology, ecology, and sediment flows beginning in the 19th century.
The Mississippi River continues as America's primary inland waterway, supporting massive barge traffic. However, it faces significant ecological challenges including dead zones, invasive species, and pollution. Multiple conservation organizations work on river restoration and management.

New York — Urban alienation and disconnection
New York City represents the urban pinnacle of humanity's separation from nature. Characters moving through Manhattan experience the city as a landscape of concrete and steel where the natural world has been entirely replaced by human construction. The city embodies the disconnection that Powers argues is at the root of environmental destruction.
New York City emerged as America's premier metropolis in the 19th and 20th centuries, built on the displacement of the Lenape and other indigenous peoples. The city's development destroyed local ecosystems and established the model of industrial urban development that Powers critiques.
New York City remains one of the world's most densely populated cities, though urban parks like Central Park and environmental initiatives represent efforts to restore some ecological consciousness. The city has become a center of environmental advocacy.

Delaware — Sycamore trees and botanical time
Patricia Westerford's research focuses on the botanical history of places like Delaware's ancient sycamore forests. Her discoveries about how trees communicate through root networks and fungal connections become the scientific foundation for understanding nature's intelligence, which Powers argues humanity has catastrophically ignored in its pursuit of exploitation.
Delaware's forests were originally dominated by mixed hardwoods including American sycamore, tulip poplar, oak, and hickory. Colonial settlement and industrial logging removed most of the old-growth forest by the 19th century. Contemporary forest recovery efforts have restored some native ecosystems.
Delaware's state forests and natural areas preserve remaining hardwood forests and riparian corridors. Conservation easements and state parks protect significant forest tracts, allowing visitors to experience the woodland ecosystems Powers celebrates.

Illinois/Midwest — Technological dominance over nature
Adam Appich and other characters grapple with nuclear power as the ultimate symbol of technological hubris — humanity's attempt to extract unlimited energy from nature's fundamental forces. The industry represents the false promise that technology can solve problems created by technology, without understanding the ecological consequences.
The United States built its first commercial nuclear power plant in 1957 in Pennsylvania. By the 1980s-90s when Powers writes, nuclear power was promoted as the clean energy solution, though concerns about waste, safety, and ecological impacts grew. Illinois became a major nuclear power state with multiple reactors.
Illinois operates multiple nuclear power plants, including the Braidwood Generating Station and Byron Nuclear Generating Station. Nuclear power remains controversial despite being promoted as carbon-free energy, with ongoing debates about waste storage and decommissioning.
Oregon/Washington — The cutting edge of environmental conflict
The northern spotted owl becomes the novel's symbol of species-level ecological crisis. Characters battle over protected owl habitat, with loggers and timber companies fighting conservation regulations. The owl represents the line where environmental ethics finally force legal confrontation, sparking the radical activism that dominates the novel's conclusion.
The northern spotted owl became the focus of one of America's most significant environmental battles in the 1980s-90s. Listed as threatened under the Endangered Species Act in 1990, the owl's protection forced a dramatic decline in Pacific Northwest old-growth logging. The conflict became known as the 'timber wars' and pitted timber communities against environmentalists.
Spotted owl habitat remains protected within National Forests and parks throughout the Pacific Northwest. Conservation efforts have had mixed success, as populations remain threatened by habitat loss, climate change, and competition from invasive barred owls. Several wilderness areas allow public visitation for wildlife observation.

New York — The engine of extraction
Wall Street and the financial system represent the ultimate mechanism of nature's destruction in Powers' vision. The novel's characters recognize that environmental destruction flows from economic systems that treat nature as infinitely exploitable capital. Wall Street's abstractions — stock prices, quarterly earnings, growth metrics — completely disconnect human decision-making from ecological consequences.
Wall Street emerged as the world's dominant financial center in the 19th-20th centuries, driving capital accumulation and investment in resource extraction industries including timber, mining, and oil. The financial system created institutional structures that prioritized short-term profits over long-term ecological stability.
Wall Street remains the global financial center, though environmental investing and ESG (Environmental, Social, Governance) investing have grown. However, critics argue these movements fail to address fundamental extractive structures Powers identifies.

Washington/Oregon — Pre-industrial ecological stewardship
Though Powers doesn't center Indigenous perspectives, the novel's environmental ethics implicitly contrast with pre-Columbian Indigenous forest stewardship. The ancient forests that captivate characters like Nick represent ecosystems maintained through thousands of years of Indigenous management. The novel suggests that industrial society's disconnection from nature represents a catastrophic break from sustainable relationships.
The Pacific Northwest's temperate rainforests were managed by Indigenous peoples including the Tlingit, Haida, Kwakwaka'wakw, and other nations for thousands of years through selective harvesting, controlled burning, and sophisticated ecological knowledge. This management created the diverse, productive ecosystems that colonizers encountered.
Several tribal nations manage traditional territories within the Pacific Northwest, and conservation partnerships increasingly recognize Indigenous peoples as crucial to forest management and ecological restoration. Public lands incorporate some Indigenous management practices.

New Mexico — Deep time and geological wonder
Carlsbad Caverns represents the deep geological time that contrasts with human timescales. Powers uses such natural wonders to emphasize nature's incomprehensible age and complexity, against which human civilization represents merely a blip. The caverns embody the sacred natural world that industrial society has learned to disenchant and exploit.
Carlsbad Caverns was formed over millions of years through sulfuric acid dissolution of limestone. It was designated as a national monument in 1923 and national park in 1930, becoming one of America's most visited cave systems. The caverns were known to local Indigenous peoples for centuries before European discovery.
Carlsbad Caverns National Park remains one of the world's most impressive cave systems, attracting nearly half a million visitors annually. The Big Room chamber is one of the largest underground chambers in North America, and visitors can view the complex ecosystem including bat colonies.
