Dry deposition and resuspension of trace elements in the remote High Sierra

Airborne size distribution and dry deposition data for seven elements (K, Rb, Cs, Ca, Sr, Ba, and Pb) were obtained in a remote subalpine ecosystem in Yosemite National Park, California during 1976 and 1977. During periods of partial snow cover, resuspension of local soil was minimal and all seven elements showed a net transport into the ecosystem from surrounding regions. With moderate winds and dry conditions, resuspension of local surface material increased, equalling or exceeding net downward flux for all metals except lead.
