21. By September 2004, surface soil and surface water levels of TCE and other chemicals were within normal levels. 22. Pumice sands from Mount Mazama and Newberry Crater appear in the surface soils throughout the Lost Forest area. 23. Wind-blown, or Aeolian, movement of surface soils created the Barmah Sandhills on the northeastern edge of this lake. 24. The physical actions of the animal loosens the surface soil , damaging roots and stems and reducing plant biomass. 25. This is due to soil aggregate formation in finer textured surface soils when subject to soil biological processes. 26. Attempts were made to dilute the concentration of radioactive material by turning over and mixing the surface soil . 27. The pulverized surface soil would collect the rain; the packed soil would store the moisture for future use. 28. Geocarpy is also linked with solifluction soils, where rapid thawing and freezing of surface soil causes almost continuous movement. 29. However, exposed mineral soil, much more so than organic-surfaced soil , is subject to frost heaving and shrinkage during drought. 30. Pumice sands from Mount Mazama and Newberry Crater also appear in the surface soils throughout the Fossil Lake area.
