This is between the small towns of Arco and Carey, which is at an average elevation of 1,800 m above sea level. IN the Craters of the Moon the protected area which features are volcanic and it also represent one of the best-preserved flood basalt area on the Continental United States.

This lies on the parts of Blaine, Butte, Lincoln, Minidoka and the Power Countries. This area which is managed cooperatively by the National Park Service and also the Bureau of Land Management. The three major Lava fields are encompass by the Monument and Preserve, which is about 1,000 km sq of the Sagebrush steppe grasslands which is to cover an total area of 2,893 km sq. These all three lava fields which lies along the Great Rift of Idaho.  The Craters of the Moon which is on the south-central Idaho, midway between Boise and Yellowstone National Park. From the Pioneer Mountains the lava, which reaches at the  Southeastward. In the Contiguous United States the craters of the moon lava field which spread across 1,601 km sq, and this is the largest Holocene-aged basaltic lava field.  The Monument and Preserve which contains more than 25 volcanic cones. lava field which is the largest of several large beds of lava which is erupted from the 85 km south-east to the north-west trending Great Rift volcanic Zone a line of weakness on the Earth's crust.  The Elevation at the visitor center is 1,800 m above sea level.  The Craters of the Moon which is found to be formed during the eight major eruptive periods between the 15,000 and 2000 years ago. The Lava which erupted from the Great Rift, a series of deep cracks which starts near the visitor center and it also stretch 84 km to the southeast. During that time the Craters of the Moon lava field which grew to cover 1600 sq km. THE King Bowl lava field and smaller Wapi also formed along the Great Rift during the most recent eruptive period.  From the foothills of the pioneer Mountain on the northern end of the monument to the Snake River on the south, weather conditions vary significantly. As the elevation which decreases from the north to south, the temperature increase and the precipitation decreases.  The average annual precipitation which ranges from 16 inches at the monument visitor center to just under 10 inches near the Snake River at Minidoka Dam. On February, the average snow depth which ranges from 56 inches at the north end of the monument to just 2 inches at the south end. The intense summer sun bakes the black lava, which generate an surface temperature of 170 degree Fahrenheit and air temperatures in the 90s. The drying winds are a daily occurrence, especially in the afternoon and may reaches 15 to 30 miles per hour. In the month of June, July,and August, the average monthly precipitation which is found to be less than two inches. The winter which transforms Craters of the Moon into a dramatic landscape of the rugged black lava and also the soft white snow. The Fall and spring are milder, which are with unsettled weather. IN the harsh condition, the delicate wildflowers that burst their life in the month may or June against the monochromatic background of the cinder slopes.  The weathers may influence the visit to the Craters of the Moon, the climate is responsible for the land and life found there.
