About Lassen
Deep, moderately well drained soils formed in mudflow deposits (lahars) and alluvium derived from andesitic volcanic rocks. Found on alluvial fans and terraces at 3,500–5,500 ft elevation on the flanks of the Cascade volcanic peaks.
K-factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
California Distribution
Named for Lassen Peak and widespread in Lassen County on the volcanic mudflow aprons. Also occurs in Plumas County on similar terrain. Used for irrigated pasture and dry grain farming.
