San Bernardino National Forest encompasses the vast majority of this high-altitude landscape, where residential developments like Moonridge and Sugarloaf meet the steep slopes of the San Bernardino Mountains. The topography is defined by significant peaks and ridges, including Sugarloaf Mtn and Heart Bar Peak, while water resources range from the southern edge of Big Bear Lake to the headwaters of the Santa Ana River. Lower elevations reveal specialized mountain meadows and flats, such as Barton Flats and Wildhorse Meadows, which have historically served as recreational and agricultural hubs. The presence of the Pacific Crest National Scenic Trail on the eastern edge highlights the area's role as a major corridor for wilderness travel. Further south, the map traces the S Fork Santa Ana River as it cuts through canyons below Poopout Hill and Grinnell Mtn.
