A lot of archeological sites are restricted to the public, so ones that are open can really offer a great experience and opportunity to those interested in the field. Pictograph Cave can be a great area for such, as it is a part of the Pictograph Cave State Park in Yellowstone County, Montana.

It measures of 93 acres, along with three other caves. This one, however, offers a place where over 30,000 artifacts and 20,000 animal remains were found. The Pictograph Cave is named after the pictographs that are from 3500 years ago, most of which are paintings of warriors, animals, and even rifles. Meanings of these works are still being debated on today.

The site was declared as a National Historic Landmark in 1964.
