About this map

Anza Borrego Desert State Park encompasses this arid landscape, dominated by the Vallecito Mountains and the prominent summit of Whale Peak. The map records an intricate network of desert hydrology, from the wide Mescal Bajada in the north to numerous drainages like Chuckwalla Wash and Bisnaga Alta Wash. Human presence is marked by a series of primitive routes, including several labeled Jeep Trails, and a notable unnamed Mine situated near the head of a canyon in the northwest.

Archeological and geological interest is highlighted by specific landmarks such as Petroglyphs and Split Rock near Hapaha Flat. These features, along with water sources like Blue Spring, indicate the vital locations where life and history converged in this desert environment. The terrain transitions from broad basins like Harper Flat and Little Blair Valley to the steep slopes of the Pinyon Mountains, providing a detailed look at the region's topographical character before modern development.
