Mount Baldy serves as a northern anchor where the Angeles National Forest meets the San Bernardino National Forest. This 1995 revision reveals a landscape defined by the sharp transition from the steep drainages of San Antonio Creek and Cattle Canyon to the residential expansion of Claremont and Upland below. The infrastructure of the foothill communities is clearly visible, showing the San Antonio Dam and the Desilting Basin designed to manage the heavy runoff from the mountains. Cultural markers include the Padua Hills Theater and several educational institutions like Webb Sch and Pioneer Jr High School. The map also details the extensive wilderness areas, such as the Sheep Mountain Wilderness, which dominate the northern half of the quadrangle with names like Potato Mountain and Sunset Peak.
