The Tiwa Indians, also known as Tigua, are a group of Tanoan Pueblo tribes which live in three areas of New Mexico including Taos. The people of Taos Pueblo have a detailed oral history which is not divulged due to religious privacy. The Taos Pueblo is the oldest continuously inhabited community in the United States dating back to more than 1,000 years. And due to maintaining traditions, no electricity or running water is allowed within the Pueblo walls. I imagine winter must present some challenges for the current residents who remain to protect their sacred traditions.
