The main incorrect term used in this diary is "steam heating."
This type of heating was used in the early 20th century as a simple method when pumps were unavailable.
By 1959, steam heating was hardly in use anywhere in Sverdlovsk, yet the term continued to be used.
In reality, it was hot-water heating—pipes designed for steam, but carrying water.
However, hot-water heating in a tent is also out of the question. It was likely a joke, much like "Evening Otorten."
In that case, there could be jokes about curtains or anything else.
Another significant error in that entry is that the city of Salekhard is named instead of Khanty-Mansiysk.
The population is listed as 8,000. It is unclear to me who made the entry containing such an error; there is no signature for that day.
The population of Khanty-Mansiysk in 1959 was 20,677.
The population of Salekhard in 1959 was 16,567.
Neither city fits the figure. The discrepancy is significant.
I do not understand the point of such incorrect entries that have no relation to the hike.
