Llallagua

Llallagua (in hispanicized spelling) or Llallawa (Aymara for a monstrous potato (like two potatoes) or animal, Quechua for the god of seed-time during the Inca period) is a town in the Potosí Department in Bolivia. It is the seat of the Llallagua Municipality, the third municipal section of the Rafael Bustillo Province.

Geography
Llallagua features a rare microclimate amidst the semi-arid tundras of Potosí and Oruro, due to its extreme elevation near 4000m. Semi-arid and with average temperatures in its warmest month sitting right on the 11 °C threshold, the city's climate straddles that of the subtropical highland climate (Cwc, according to the Köppen climate classification), with subpolar oceanic characteristics and a cold semi-arid climate (BSk). Summers are cool and wet with daily highs rarely rising above 22 °C, while winters feature cooler days with much colder nights averaging −4 °C. These low temperatures are a result of the extreme precipitation deficit during the winter months with the resulting aridity leading to an increased diurnal temperature variation.
