STS073-744-053 San Bernardino Mountains, California, U.S.A. October 1995 Rugged mountains and urban development are featured in this photograph southeast of San Bernardino. The mountain vegetation (red) along the northern edge is part of the San Bernardino Mountains and San Bernardino National Forest. Discernible are several natural and manmade features--Lake Perris, the westernmost reservoir with a small island near its center; several prominent canyons aligned in a general east-west orientation; a short section of the Santa Ana River, a highly reflective winding narrow river valley to the northwest; and cultivated field patterns near the two reservoirs. The symmetrical dark feature is the tip of the Shuttle tail.
