About this map

Island of Hawai'i terrain dominates this survey of the high-altitude pass between massive volcanic peaks. The landscape is defined by successive volcanic events, clearly delineating the extent of the Lava Flow of 1843, the Lava Flow of 1855, and the Lava Flow of 1935. These flows create a chronological record of the island's geomorphology, cutting across the Humu'ula Saddle. Modern infrastructure follows these natural corridors, with Saddle Rd and Humuula Rd providing transit through the volcanic field.

Local landmarks such as Pu'uhuluhulu and Kalaieha stand out against the contour lines of the slopes. Smaller volcanic cones like Pu'u'o'o, Ho'okomo, and Huikau dot the region, while drainage patterns are visible in the northern reaches at Waiaama Gulch and Waikahalulu Gulch. The intersection of Mauna Kea Access Rd and Mana Rd highlights the area's significance as a junction for high-elevation access.
