While in Blanding, Utah, I did some hiking to the ruins of an Anasazi Indian cliff dwelling.
It is truly fascinating to see where these people lived and to imagine what the area must have looked like with the cliff dwelling in full operation more than a thousand years ago.
The cliff forms a natural protection and the Anasazi appear to have taken excellent advantage of it!
You can see the cliff dwelling construction technique in the following photo. Lots of rocks and mud. It is still quite strong!
