About this map

Morongo Valley occupies a strategic high-desert transition between the San Bernardino Mountains and the Little San Bernardino Mountains. This 2021 survey details the residential development of Little Morongo Heights and Palm Wells, illustrating how the community has structured itself along the Highway 62 corridor. The geography is defined by seasonal water systems like Big Morongo Cr and Dry Morongo Wash, which drain toward the Coachella Valley to the south.

Local landmarks such as Morongo Lakes and the named water sources of Sherman Shady Spring and Leopard Spring highlight the critical role of hydrology in this arid landscape. The map provides a contemporary record of property boundaries and street networks, including Altadena DR and Pioneer DR, making it a precise tool for modern local history and land-use studies near the San Bernardino and Riverside County line.
