i'm not going to go into heavy detail, i want to take you down here into the sierra madre. i was following routes all over for the house of rain, trying to figure out where the anastazi went when they left house of rain. many of them made the modern pueblos but other groups continued south. i followed pottery trails down into the sierra madre where my wife and two others went out and we came to these cliff dwellings. it seemed like every single cave we looked into had cliff dwellings. and this wasn't a place with trails. this wasn't a known location. many of these sites were pristine. they were just -- it looked as if people had just left suddenly, just like all the stories in here. little cliff dwellings, little granaries, little sites falling apart. larger sites. this site went actually 5 layers deep into this cave. very particular to this region were these shaped storage rooms. this one is about 10 feet high. often they would have door stones sealing them on the top. and they were of all kinds of shapes and sizes, but they specific to that area. that's the smallest one w
