Physical Environment

Geologic forces have created the landscape of Pinnacles, but a climate of hot dry summers and winter rains has also shaped the terrain. The vegetation of the park transforms each year as the rain stops and temperatures climb; hillsides go from vibrant green to golden brown within days. Many of the chaparral plants thrive when fires burn through to make room for new growth. Streams that are dry throughout the summer can flood during the winter and spring rains.
