Hollow Earth Entrances can be found all over the Planet
In almost all cultures and places on the planet, there is mention of places where we can enter the Earth both in third dimension and via clairvoyance and remote viewing. The Navajo and Havasupai often discuss the hollow earth entrances that exist in the Grand Canyon, and many of their ancient stories reflect this truth. It is also said that the Hopis came out of the Earth from one of the earth entrances and the ant people images on their rocks are pictographs of just some of the species/people who live inside our planet.
