Yes, it has snowed in Death Valley, although it is a rare occurrence.
While Death Valley is known for its extreme heat and arid climate, snow has been recorded there. Measurable snowfall, specifically 0.5 inches, was recorded at Greenland Ranch (the official recording station) on January 29, 1922. Additionally, the National Weather Service (NWS) in Las Vegas has records indicating trace amounts of snow on three other dates: January 4-5, 1974, and January 22, 1962.
Therefore, while not common, snow in Death Valley is a documented phenomenon.
