They are located in the Verdugo Mountains of Southern California and bear the name of the local band of indigenous Tongva, "Hahamog'na."
[2] Hahamongna was one of the largest Tongva villages in the greater San Fernando Valley area, along with Cahuenga, Tujunga, and Siutcanga.
[3] Hahamongna was located in present-day Glendale and existed on the lower southwestern Verdugo Mountains slopes and the eastern San Fernando Valley plain with the free-flowing Los Angeles River just south.
The site of Hahamog-na is now within the protected natural area of Hahamongna Watershed Park, a 300-acre (1.2 km2) habitat and plant community blend of freshwater marsh wetlands, riparian zones, native oak woodlands, and chaparral elfin forests.
[4] The band of Tongva people who lived in the area of the Verdugo Mountains that contains both settlements was named the Hahamog-na and Hahamongna by some non-native immigrants and historians.
