O homem arde daqui a 15 dias...


The Black Rock Desert is a thoroughly flat, prehistoric lakebed, composed of a hardpan alkali, ringed by majestic mountains. Daytime temperatures routinely exceed 100ºF and the humidity is extremely low [...] At nearly 4,000 feet above sea level the atmosphere provides much less filtering of the sunlight [...] It takes nearly everyone a day or so to adjust to the desert climate. [...] However, when the sun drops over the horizon, temperatures can quickly plummet fifty degrees. Overnight lows in the 40's can seem exceptionally cold after extensive daytime sun [...] Storm cells, fed by rising thermals that stream upward from the surrounding mountains, may arise in the late afternoon or evening and bring high winds, lightning and (sometimes) rain into camp.
