South Dakota 87

Greetings, intrepid scholars of geology and infrastructure. You have arrived at South Dakota Highway 87, globally recognized as the Needles Highway. …

As we snake our way upward, look to the towering columns of rock that give this highway its moniker. These are the Needles, and their geological origin story is a fascinating study in deep time and erosive power. …

We approach the definitive crucible of this journey: the Needles Eye Tunnel. This is an engineering marvel that routinely tests the spatial awareness and nerve of modern drivers. …

Just beyond the primary tunnels, the road opens up into an area defined by a specific cluster of formations known as the Cathedral Spires. These particular granite towers routinely reach heights of over one hundred feet, jutting…

It is crucial we pause to consider a specific historical anecdote that occurred on this very stretch of road, an event that forever altered the cultural landscape of South Dakota. In the early nineteen twenties, state historian…

As the highway continues, it forces us through subsequent feats of excavation, notably the Iron Creek Tunnel and the Hood Tunnel. While perhaps lacking the extreme notoriety of the Needles Eye, these passages are equally…

Before we exit the Needles Highway, we must conduct a final survey of the high-altitude ecology that defines this route. Operating at elevations nearing or exceeding six thousand feet, the biological rules here differ…

Our analytical transit of the Needles Highway concludes here. It is incumbent upon us to evaluate what we have just experienced. …
