Spring Wildflowers on Rolling Hill, Carrizo Plain National Monument, California

Rolling hills in the Temblor Range are covered with a variety of colorful spring wildflowers during a superbloom in the Carrizo Plain National Monument in California. During superbloom years, an unusually high number of wildflowers blossom at the same time, usually the result of wet winter and spring weather. The seeds may have been dormant for years in the more typically dry desert soil.
