Tlacolula de Matamoros
The caves and rock shelters vary in size and what they contain. Many contain paintings and other forms of graphic representation. Contents include ceramics and stone tools. The corn materials show similarities to the first vestiges of the domestication of wheat and rye in the Middle East. One of the deepest caves is called the Cueva de la Paloma. The caves have been studied since the 1960s, especially the Cueva de Guilá Naquitz (white stone in Zapotec), which has some of the best evidence for the domestication of corn and squash, which dates back more than 10,000 years. Other caves, such as those near Yagual and Mitla confirm findings at Guilá Naquitz and show human occupation to about 8000 years BCE the sites also show similarities to the Head Smashed and Buffalo Jump Complex sites in Canada. Many more smaller caves with similar artifacts are thought to exist in the area.
Tuckaleechee Caverns
Tuckaleechee Caverns () is a set of caverns and AAA GEM attraction in Townsend, Tennessee, near the Smoky Mountains.

The caverns are known for the "Big Room", an immense cave/cavern room that a football stadium could fit inside. The caverns have stalagmites reaching 24 feet tall with flow-stone formations hundreds of feet in length and width.
