The History250 Semiquincentennial Series is a 50-state historical scavenger hunt project created to celebrate America's 250th anniversary in 2026.
Each state is explored through a curated selection of 100 significant destinations, drawn from across its full history—from ancient settlements and Indigenous heritage to modern marvels of innovation. For every destination, a poetic, triple-couplet clue invites readers on a whimsical journey of discovery, blending education with entertainment. The series highlights architecture, transportation, politics, industry, arts, and everyday life—offering an inclusive, engaging portrait of the American story one clue at a time. The Semiquincentennial isn’t just a mouthful—it’s a reminder that history is alive, sometimes weird, and always waiting to be rediscovered. The stops we’ve chosen span more than 250 years of American experience—rural and urban, solemn and playful, visible and obscure. Whether you’re traveling by road, by ebook, or by imagination, we invite you to explore 100 places and uncover the stories state-by-state that built and shaped the nation. Bring your curiosity. Bring your camera. Bring your sense of adventure. Whether you’re a lifelong native or just visiting for the week, these places have stories to tell—and surprises to reveal. Let’s go find them.
