Bryce Canyon contains the largest concentration of hoodoos on Earth. Situated along a high plateau at the top of the Grand Staircase, its high elevations include numerous life communities, fantastic dark skies, and geological wonders that defy description. Because of its high-elevation climate, weather there through autumn, winter, and spring can be highly variable. From October to May, temperatures fall below freezing nearly every night. The area typically experiences its coldest and snowiest periods from December through February. Spring storms in March and April can still produce heavy snowfall that may impact travel in the region. Summer highs are typically in the 70s-80s F, and afternoon thunderstorms are common in July and August.
