Question for all my soil science friends out there:

Where in the soil profile is the oldest soil?

#soil #soilprofile

A range of #Oregon #volcanic #soils developed over fragmental #pyroclastic #rocks and #tuff.

All are well drained soils that show little compaction or development of #clay…though some are used extensively for local agriculture.

1) Butte Falls
2) Prospect
3) Bonanza (Hildebrand)
4) Hood River (Parkdale)
