Why you've never heard of Hilo's Kalanakamaa gulch

Detailed Description

An 1891 map of Hilo, produced by Surveyor E.D. Baldwin, is superimposed on a recent Google Earth image of the town to show the location of the Kalanakamaa gulch relative to the ALENAIO and Waiākea streams. The 1880-1881 Mauna Loa lava flow, shown in orange (lower left), reportedly diverted water from the Kalanakamaa gulch, which has since been filled in by construction and no longer exists.
