    • Cold temperatures (inhibit biological activity which utilizes iron and manganese as electron acceptors)
    • Low amounts of iron
    • Oxygenated groundwater
  • Presence of redoximorphic features may not reflect the current hydrologic condition
    • Recently drained soils may retain presence of reduced features
    • Changes in microclimate are indicated by sharp boundaries in the soil
    • Contemporary features should have diffuse boundaries
