HONEYJONES SERIES

The Honeyjones series consists of very deep, well drained soils on mountains and breaklands. They formed in material weathered from metasedimentary bedrock, mainly siltite and argillite, with a thick mantle of volcanic ash. Saturated hydraulic conductivity is moderately high. Slope ranges from 15 to 85 percent. The average annual air temperature is about 43 degrees F and average annual precipitation is about 38 inches.

GEOGRAPHIC SETTING: Honeyjones soils are on mountains and breaklands. Slopes range from 15 to 85 percent. These soils formed in material weathered from metasedimentary bedrock, mainly siltite and argillite, with a thick mantle of volcanic ash. Elevations range from 2,200 to 4,900 feet (671 to 1494 meters). The average annual air temperature ranges from 41 to 45 degrees F. The average annual precipitation is 26 to 45 inches (660 to 1143 mm). The average frost-free period is from 60 to 120 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ahrs, Hugus, Latour, Lotuspoint, and Pinecreek soils. Ahrs soils are on southerly-facing mountain slopes and are loamy-skeletal. Hugus soils are on foothills and dissected terraces, and have loamy-skeletal argillic horizons. Latour soils are on mountain slopes at higher elevations and are cryic. Lotuspoint soils are on south-facing ridges and canyonsides, and are mesic and have bedrock at depths of 20 to 40 inches. Pinecreek soils are on south-facing mountain slopes and have an umbric epipedon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained; moderately high saturated hydraulic conductivity.

USE AND VEGETATION: These soils are used for timber production, livestock grazing, recreation, wildlife habitat, and watershed. Potential natural vegetation is mainly western hemlock, western redcedar, grand fir, western larch, western white pine, and Douglas-fir, with an understory of queencup beadlily, goldthread, American trailplant, western rattlesnake plantain, piper anemone, sweetscented bedstraw, oneleaf foamflower, violet, Oregon fairybells, starry false-Solomons-seal, and Columbia brome.

DISTRIBUTION AND EXTENT: Northern Idaho. This soil is extensive. MLRA 43A.
