在南达科他州荒芜之地发现的黄石公园火山灰在地质上将这两个公园连接起来。 Yellowstone's volcanic ash found in South Dakota's Badlands links the two parks geologically.

黄石公园和南达科他州的巴德兰国家公园在地理上相距遥远,但最近的调查结果表明存在地质联系。 Yellowstone National Park and South Dakota's Badlands National Park are geographically distant, but recent findings suggest a geological link. 在荒芜之地的 Brule 地层中发现了黄石超级火山的灰烬，这表明黄石公园的火山物质很久以前就到达了该地区。 Ash from the Yellowstone Super Volcano has been discovered in the Badlands' Brule Formation, indicating that volcanic material from Yellowstone reached this area long ago. 这些证据表明,尽管两个地点目前分开,但这两个地点之间有历史火山联系。 This evidence points to a historical volcanic connection between the two sites, despite their current separation.
