Thanks guys
Most of these ruins are on overhung ledges in canyons or branches of canyons. Some of the canyons have springs and fairly constant water, others are dry but may have potholes that fill up with water when it rains.
Some of the ruins are habitation sites where the people lived, the ones with the doors were likely for storage of food items like corn or squash, and some old corn cobs were seen in some areas. A number of the habitation sites were very difficult to get to so they were defensible positions. Lewis Lodge in an earlier post was built so there was only one way in past a door on a wall that went to the edge of a ledge. There are a lot of thoughts about various ruins, but a fair amount is educated guesses as who knows what they were thinking.

Sorry to be missing Blade and you guys this year
