           Quantifying soil
     changes.  Soils were sampled
with a steel-box sampler to a depth
          of 30 cm. Profiles were separated into 4
    horizons (O, A, B1, B2), yielding quantitative
per-unit area estimates on soil mass. Samples were
initially collected in 1992 and again in 2003 after the Biscuit Fire.  Previously collected samples were preserved in the LTEP samplebase archive.
