On March 18, 2011, the Homolovi State Park (formerly the Homolovi Ruins State Park) was re-opened to the general public. Prior to this, the Arizona State Parks produced a short video on Homolovi to introduce people to the Park. As you watch the video, take special note of the remarks made by Hopi anthropologist Micah Lomaomvaya. I should also point out that an excellent source for those interested in Homolovi is Homol’ovi: An Ancient Settlement Cluster by E. Charles Adams. Adams is also featured in the video.

It is important to know this. Impressive application of science helping to understand Hopi culture.
