Document 11: Richmond, Virginia: Precipitation is rather uniformly distributed throughout the year. However, dry periods lasting several weeks do occur, especially in autumn when long periods of pleasant, mild weather are most common. There is considerable variability in total monthly amounts from year to year so that no one month can be depended upon to be normal. Snow has been recorded during seven of the twelve months. Falls of 3 inches (7.6 cm) or more within 24 hours occur an average once per year. Annual snowfall, however, is usually light, averaging 10.5 inches (27 cm) per season. Snow typically remains on the ground only one or two days at a time, but remained for 16 days in 2010 (January 30 to February 14).

It takes place in the same fictional universe as "Genome", about one hundred years prior to the novel's time frame. Unlike "Genome", "Dances on the Snow" hardly deals with the issue of genetic engineering but does touch on the issue of cloning.

Document 14: Thirteenth City: Thirteenth City (, "Trinadtsatiy gorod") is a science fiction novella written by the popular Russian science fiction and fantasy writer Sergey Lukyanenko.

Document 15: Boston: Boston's coastal location on the North Atlantic moderates its temperature, but makes the city very prone to Nor'easter weather systems that can produce much snow and rain. The city averages 43.8 inches (1,110 mm) of precipitation a year, with 43.8 inches (111 cm) of snowfall per season. Snowfall increases dramatically as one goes inland away from the city (especially north and west of the city)—away from the moderating influence of the ocean. Most snowfall occurs from December through March, as most years see no measurable snow in April and November, and snow is rare in May and October. There is also high year-to-year variability in snowfall; for instance, the winter of 2011–12 saw only 9.3 in (23.6 cm) of accumulating snow, but the previous winter, the corresponding figure was 81.0 in (2.06 m).[d]
