Ecological sites found on landforms that were once covered by Lake Lahontan
Piedmont slopes and associated hills and fans
Soils formed in lacustrine influenced alluvium. Landforms are dominated by alluvial flats and plains. Slopes are less than 10 percent and the elevation is typically less than 1,350 meters (4,429 feet)....Basins LRU: The majority, but not all, of this area was underwater during the most recent high stand of Lake Lahontan.
Landforms and elevations not as above... go to 2
Soils formed in mixed alluvium with some residuum or colluvium. The landforms are dominated by piedmont slopes. The elevations range from 1,350 to 1,780 meters (4,429 to 5,840 feet).... Hills and fans: Low hills and rock pediments characterized by typic aridic soil moisture regime are also included in this LRU.
