Pastaza Province in the context of Baños de Agua Santa

Shuar (which literally means "people", also known by such (now derogatory) terms as Chiwaro, Jibaro, Jivaro, or Xivaro) is an indigenous language spoken by the Shuar people of Morona Santiago Province and Pastaza Province in the Ecuadorian Amazon basin.

Puyo (Spanish pronunciation: [ˈpuʝo]), also known as El Puyo, is the capital of Pastaza, a province in Ecuador. Puyo is located at an altitude of approximately 950 metres above sea level by the Puyo River, a tributary of the Pastaza River, which eventually leads into the Amazon River. True to its name, derived from the Kichwa word for "cloudy", the local climate is a wet one and the weather is often overcast.

Puyo was founded in 1899. Located between Baños, and the Amazonian cities of Tena and Macas, Puyo is the commercial, cultural and political capital of the region. In late 2006, the city had approximately 25,000 inhabitants. It was the fastest growing city in Ecuador in 2006. The seasonal changes in the climate are relatively small, and daytime temperature typically range between 18 and 24 °C, with sun and generally short, but heavy periods of rain daily.
