Between 1841 and 1869, an estimated 500,000 people passed this distinctive spire on their way to Oregon, California, and Utah. After weeks of flat prairie, Chimney Rock signaled that the emigrants were making progress - the Rockies were getting closer. The rock was a meeting point, a campsite, and a powerful symbol. Many carved their names into its soft stone base. Today, Chimney Rock is a National Historic Site, still standing but slowly eroding. The spire that guided generations west is losing several inches of height each decade, gradually returning to the earth.
