  1. Remote Area Soil Proxy Model Crystal Briggs Toby Rodgers Mt. Vernon Soil Survey Office

  2. soils information In a watershed RASP A movement to remedy this far, far away, did not exist. MODEL was begun...

  3. Introducing theRemoteAreaSoilProxy Model

  4. RASP Model Based on research conducted by: • Toby Rodgers (1997-2001) • Pasayten and Sawtooth Wilderness Areas • Crystal Briggs (2001-2004) • Thunder Creek Watershed in NOCA

  5. North Cascades NP Thunder Creek Watershed Glacier Peak Olympic NP Mount Rainier NP Mount St. Helens Mount Mazama (Crater Lake) ~ 300km south

  6. Why Model? • Remote areas not mapped • Inaccessible and rugged terrain • Traditional methods would require many years

  7. Model Development What’s Needed? • Understanding of soil patterns in the field • Efficient way to map patterns • Digital data layers to represent SFF

  8. S = ƒ (cl, o, r, p, t, …) • Parent Material – reworked glacial till & tephra • Topography – slope, aspect, landform • Vegetation – coniferous, deciduous, and herbaceous • Climate – • Udic • Frigid or Cryic • Time - <13,000 yrs

  9. Vegetation Douglas Fir Water Subalpine Fir Rock, Sparsely Veg Mountain Hemlock Snow/Ice Meadow Heather Western Hemlock Shrub Conifer Mix Bigleaf Maple Western Redcedar Pacific Silver Fir Red Alder Vegetation

  10. Landform

  11. Andisol Spodosol Debris Cone Inceptisol Valley Wall Pleistocene Moraine

  12. SOIL-FORMING FACTORS DIGITAL DATA LAYERS TO CREATE A SOIL MAP PROXIED BY Climate & Organisms SOIL DISTRIBUTION MAP DEM Topography Landform Vegetation Stability & Parent Material

  13. Cell-based Modeling • Rasters or Grids • Pixels • 30m • Unique value for each pixel

  14. If valley wall & frigid conifer & WI <11 then Typic Udivitrand & Andic Haplorthod

  15. Typic Haplorthod-Typic Dystrudept Typic Dystrudept-Typic Haplorthod Andic Haplorthod-Typic Dystrudept Typic Dystrudept-Andic Haplorthod Typic Udivitrand-Andic Haplorthod Typic Dystrudept-Typic Udivitrand Vitrandic Dystrudept-Typic Udivitrand Spodic Dystrocryept-Andic Haplocryod Andic Haplocryod-Typic Vitricryand Typic Melanocryand-Vitrandic Dystrocryept Andic Haplorthod-Typic Udivitrand Typic Dystrocryept-Typic Haplocryod Typic Vitricryand-Andic Haplocryod Humic Dystrocryept-Typic Melanocryand Soil Distribution Map

  16. North Cascades NP Olympic NP Mount Rainier NP • 2005 - correlate Thunder Creek Watershed • 2006 and beyond - other watersheds in the national parks where landform mapping has been completed (Elwha) Washington State

  17. Thank you
