"Dear Mary,
"New Mexico and Arizona have the most complex of united cavern systems in the USA, which go into Mexico too. The cavern inhabitants are not all beneficial, but most are not destructive to surface people, and they do not interfere with us to any great extent. Outside of deros and rays, the main thing is that you may get a contact, if and when you are near them. You will either think it is a spirit, or else you'll think you're crazy, while they are only trying to let you (know) that they do exist in the caverns. Here are some places that could be searched:
"Go about 14 to 20 miles northeast of Pie Town, N.M. Go east through Pie Town on the paved highway, about 14 to 20 miles. Somewhere along there is a gravel road that turns north to 'El Moro' National Monument. As you go north on the gravel, you'll see a fence on the east side of the road. When the fence comes to an end, park and walk along the fence to the east. Look for a FLAT SQUARE ROCK on your left, as you walk east (watch for snakes).
"The ground has caved in under one corner of the rock and you can squeeze into the hole. A good light is needed, and you will find yourself walking down man-made wide steps that go down into a large hall. In the center is some kind of alter of a round shape. Further on are more steps going down deeper into this cave. While hunting in this area, a man found this cave, but they didn't have any lights, only matches. He planned to come back later, but didn't return until a few years later. He was so curious that he couldn't get it out of his mind. To make it short, he couldn't find it again, no matter how much he searched - it was futile.
"Now, around Farmington, N.M., and also along route 666, in the mountains on both sides, I get strange sensations (ESP) that need to be explored. The Organ Mts. in Las Cruces, N.M. and the Franklin Mts. in El Paso are also connected with the cavern world. There are the Black Range Mts. and the old ghost town of Mogollon, N.M., which I have explored and photographed the unseen worlds around this area."
