The Chaco is a very uninviting region of South America, mostly in Paraguay and Argentina, but also partly in Bolivia. It is often referred to as the Green Hell on Earth. It is flat country in Paraguay and northeastern Argentina. The Rio Paraguay separates the two countries for a while, before the river turns north to Brazil.
The border between the nations then follows the Rio Pilcomayo, which one can walk across. In the summertime, temperatures in the Chaco can reach 50C (about 125F). There is very little rain -- even less further north. In Paraguay, the lower Chaco adjacent to the Rio Paraguay is a series of floodplains, which floods every year to a depth of a foot or two but a hundred miles in extent.
The region supports large populations of wildlife. Farther west, and north, the Chaco supports a pygmy forest, whose trees and plants are armed with razor-sharp needles. The area is uninhabitable. Two-thirds of Paraguay is Chaco, but it contains less than 2% of the population. Jaguars abound (not the British vehicles!). In Paraguay there are natives who have not accepted any contact with modern society -- they prefer to remain apart. In fact, they insist in a most violent manner.
The Argentine Chaco is just as uninviting, but in Argentina things tend more toward desert further west towards the Andes, such as the Province of Jujuy (pronounced who-WHO-ee).

It was very common in 1923 that Germans would go wherever there was work to be found in the provinces of Entre Rios, Santa Fe and some smaller amount to La Pampa. Furthermore, there are large colonies of Germans in Paraguay and the province of Misiones, and given the proximity of Charata, Chaco, it was a very likely the destination for people, who immigrated in 1923 from Hamburg/Germany to Charata, Chaco.
It also has been pointed out that here have been many cases of stolen letters (in Buenos Aires), especially those coming from abroad, which are "suspected" to contain cash or internatinal response coupons, or even checks. Although newspapers not always answer the letters, institutions like embassies or the Automovil Club Argentino do answer them. However, you need a lot of patience and insistence.
