Our second hike while in Bluff took us to Cold Springs Cave.  Within the large cave, lies the remains of a large kiva.  This was an easy walk too once you found the right way to go.  Luckily we had our master guide (my Dad) who knew his way around these parts quite well.  In addition to the kiva, there are rooms and even a door way that has been there for hundreds of years.  You can also find grinding spots they used to use in the rocks.
