Indeed, the hottest and lowest area in North America lies in Death Valley, in the heart of Eastern California. Geologically, Eastern California is mostly part of the Basin and Range Province, marked by crustal extension, with horsts and grabens. Volcanism is also evident in this region. Climate The majority of Eastern California experiences two seasons, a long, dry summer and a milder winter in which the rain is concentrated. Most higher elevations experience four distinct seasons. There are some areas where the weather is very diverse. The Sierra Nevada mountain range has larger amounts of snowfall, while the Imperial Valley has more arid conditions.
