You are driving down a road off the main highway near Deming, New Mexico. Suddenly, in the midst of a mesa of tall yellow grass, you see amazing columns of stones. Some stones are forty feet tall. As you get closer, you see that other stones form arches, and still others appear as clusters of stone creatures. Welcome to the City of Rocks State Park. When volcanoes erupted in this area, millions of years ago, they spewed out fiery pieces of rock that settled and fused to form a large layer of rock. The layer cooled and then cracked. Over the years, wind, sand, rain, and other natural forces sculpted the rock into the shapes you see today. The volcanic activity also produced hot springs in the area. The park is about 28 miles northwest of Deming. The road that takes you to the park continues north to the Gila National Forest.
