From study and seeing an old videotape of a Hopi elder, I believe Mother's Navel (my name) was a sacred Hopi spiritual ground. I was introduced to it by a manzanita tree after hiking up into the crater of Red Mountain. I was physically exhausted from hiking all day and visiting other volcanos, so literally ran out of gas hiking up and reached out to a manzanita tree to help me get my backpack off and sit down. No sooner sat down, and the tree says "You're not done yet; go back down about 100 feet and then to your left but don't fall in." Following instructions I ended up looking down about 300 feet in what became for me Mother's Navel, witnessing 13 hoodoos (scientific name), looked like elders standing guard at its entrance. I did not have a rope (and wouldn't have tried it if I did, so walked out and tried to find a way in on ground level. I did notice that a lot of runoff from the volcano channeled down into Mother's Navel.
