HAGENBARTH SERIES
The Hagenbarth series consists of and very deep, well drained soils formed in loess influenced alluvium, colluvium, and slope alluvium from sedimentary, metasedimentary, and igneous intrusive and extrusive. Hagenbarth soils are on mountains, hills, ridges, lava plains, canyons, calderas, alluvial fans, interfluves, swales and valley floors[RC-NIFI1.1]. Slopes are 0 to 75 percent. The mean annual precipitation is about 580 mm, and mean annual air temperature is about 3.3 degrees C.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive Pachic Argicryolls
