Gender is what actually gets expressed â how we look, how we act and how we feel. While sex is determined by what is written into the chromosomes or what is dictated by our biology, known as genotype, it is the interaction between the genes (genotype) and the environment that determines gender.
Here are the average temp in Yosemite Valley (where CV is located) by month: www.nps.gov/yose/planyourvisit/climate.htm. Also beginning of September is usually still quite warm. Nights can have a bit of a chill, but nothing a couple of blankets can't handle.
Weather: Winter in Yosemite is snowy and cold, though sunny and chilly days are not uncommon. Fire & Smoke: Hazy or smoky conditions may occur even during winter. In some areas, the park may have prescribed fires to mimic natural fires to promote forest health and reduce the risk of larger fires as conditions allow.
