Pinnacles National Park, California, United States

Jagged pinnacles and spires, monoliths and unusual caves—welcome to Pinnacles National Park in central California. It all began in 1908 when President Theodore Roosevelt designated the area as a national monument. Later in 2013, Pinnacles earned its status as a national park. As we celebrate the anniversary of its establishment today, let"s take a moment to appreciate this landscape. This land owes its formations to an ancient volcanic eruption that occurred 23 million years ago. The fiery beginnings made towering spires, cliffs and talus caves, created by falling boulders wedged into narrow canyons. Over millennia, tectonic forces shifted the landmass northward, leaving the park far from its volcanic birthplace. Talk about a journey!
