Useful for your trip

Tip
Visit the Mammoth Site near Hot Springs in the southern Black Hills. It contains the largest collection of mammoth remains ever found in one place in the Western Hemisphere with 61 mammoths excavated so far.
Tip
The Mammoth Site is an active archaeological dig where excavation continues every year. Bones remain embedded in clay and are still being carefully revealed, so you can see science in progress.
Tip
Visit Wind Cave in the Black Hills, the sixth longest cave in the world with over 170 miles of explored passages and 95% of the world's known boxwork formations (rare honeycomb-shaped calcite structures).
Tip
Mount Rushmore receives over two million visitors annually. Plan accordingly and expect crowds at this major attraction in the Black Hills.
Timing
The Crazy Horse Memorial face was first unveiled in 1998 after 50 years of construction. The project is still ongoing and funded by donations and admission fees with no completion date set.
Tip
Explore Spearfish Canyon, which according to the documentary is a hidden canyon in the Black Hills older than the Grand Canyon, offering an alternative to more famous attractions.
Tip
Visit the Badlands National Park to see layers of rock that record 75 million years of geological history. Erosion reveals new fossils with every rainstorm.
Tip
The Black Hills are geologically among the oldest mountains in North America with a granite core formed nearly two billion years ago, making them significantly older than the Rocky Mountains.
