Chelan forest (Rex Creek fire)
Washington State, Chelan County, United States
Soils
- Type
- Soil
Litter and O horizon of a central Washington forest studied for the mercury released by the 2001 Rex Creek fire; mercury similar to coal mercury, so forest fires cannot be told apart from coal combustion by δ202Hg alone (Biswas et al., 2008). Indicative coordinates (Chelan town).
