Winter photo of salt-scar area. Maximum
depth of erosion is about 2 meters. The original soil profile is
preserved in the pedestal in the upper right. Saline
water seeps to the surface in the middle of the photo and
flows to Skiatook Lake.

Pooled oil or tank sludge stored
in shallow pits. A pipe exits the pit through the berm.
This is the freshest hydrocarbon material at the A-site.
|
Weathered oil in pit. The pit bottom is of
low permeability material.

Salt scar downslope from
the two pits. Grasses have partly revegetated the area.

View from the lower part of the salt scar
looking south upslope toward the head. Salt releases from the underlying
soil and bedrock persist at several sites in the scar, including
the white area shown here.

Lower part of the salt scar
looking to the lake. Small white patches in the
foreground of the picture are salty area. These salts
wash into the lake with surface-water runoff.
