Lithic pieces found in the strata of the different caves explored, have made it possible to determine that the oldest inhabitants of the region were here 12,960 years ago, leaving even today, samples of their culture, cave expressions and the certainty that this place was about 13,000 years ago a place with abundant water and pastures that determined the approach of a large number and variety of species of the time.

In the area there is evidence that 13,000 years ago, Mapuche and Tehuelche communities coexisted, living of hunting guanaco and choiques, fishing, and collecting mapu fruits, enduring strong winds and very cold winters.

When the Spanish conquerors arrived, they ran out of freedom, their economic and geopolitical interests incorporated this territory into the agro-livestock market.

The construction of this project achieved one of its objectives, that of promoting settlements in Patagonia, allowing the emergence of many localities in the northern area of Santa Cruz.

November 25, 1911 appears as the date of arrival of the rails at "Km 200", the name by which Pico Truncado would be known for a long time, given that this is the distance that separates the station from the headwaters located in Puerto Deseado.

Until the middle of the 20th century, the time of the discovery of oil in Cañadón Seco, Pico Truncado had a small population, with no more than five hundred inhabitants who lived from sheep and cattle farming and from the commercialization of their products through the railway.

Pico Truncado was made official as a town by a founding document, the decree of July 11, 1921 signed by then President Hipólito Yrigoyen.

In spite of the State's attempt to make it disappear forever, this means of transport contributed to the development of localities around the railway, consolidated the port action of Puerto Deseado and made Pico Truncado emerge, ensuring the growth of Las Heras and three villages; Fitz Roy, Jaramillo and Koluel Kayke.

The discovery of gas near the city was accidentally made by an inhabitant of Pico Truncado, Don Manuel Caamaño, while he was digging a well for water.

The Gas Pipeline Pico Truncado-Buenos Aires was opened on March 5, 1965, also the fluid treatment plant, which brought a new quota of growth to the city.

An important achievement of this project was to have placed the first clean energy module in the Esperanza Base, which consists of an electrolyzer, a wind turbine, a generator and a kitchen, transformed to work with hydrogen.
