TYPE LOCATION: Island of Maui, Maui County, Hawaii; Kilohana Quadrangle - 20 degrees 43' 30" north and 156 degrees 16' 50" west, 300 feet south of Olinda road and about 0.4 mile southeast of Olinda Prison Camp.
RANGE IN CHARACTERISTICS: Depth to slightly weathered andesite and basalt from 40 to more than 60 inches. Stones are on the surface in some places. The mean annual soil temperature is 57 degrees F. The B horizon has hue of 5YR or 2.5YR, value of 3 or 4 moist, 4 through 6 dry, and chroma of 4 through 6.
COMPETING SERIES: These are the Hanipoe, Kaipoioi, Kapapala, Laumaia, Paaiki, Pane, Tantalus and Umikoa series. All of these soils have an umbric epipedon. Also, Hanipoe and Pane soils have prismatic structure in the upper part of the B horizon; Kaipoioi soils have chroma of 1 in the umbric horizon and are nonsmeary; Kapapala soils have cemented sandy ash layers at a depth of 20 to 40 inches; Paaiki soils have silty clay in the lower part of the B horizon and have mean annual soil temperature of 60 degrees F; Tantalus soils are ashy over cindery in the particle size control section and have mean annual soil temperature of 70 degrees F.; and Umikoa soils are not smeary throughout the B horizon.
GEOGRAPHIC SETTING: The Olinda series are on uplands at elevations of 2,500 to 5,000 feet. Slopes are 4 to 40 percent. The soils formed in volcanic ash and residuum underlain by andesite or basalt. Mean annual rainfall is 40 to 60 inches, mean annual temperature is about 57 degrees F., average January temperature is 54 degrees F., and average July temperature is 60 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Kaipoioi and Pane soils and the Makawao soils. Makawao soils have an argillic horizon.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately rapid permeability
USE AND VEGETATION: These soils are used for pasture and woodland. The natural Vegetation is Bermuda grass (Cynodon dactylon), bracken fern (Pteridium aquilanum), eucalyptus (Eucalyptus spp.), gorse (Ulex europaeus), gosmore (Hypochaeris radicata), Natal redtop (Rhynchelytrum), pukiawe (Styphelia douglasii), rattailgrass (Sporobolus capensis, sweet vernal (Anthoxanthum odoratum), and Yorkshire foggrass (Holcus lanatus)
DISTRIBUTION AND EXTENT: Island of Maui, Maui County, Hawaii. This series is inextensive, with a total of about 4,600 acres.
