Dear Mr. Zeeb:
Soils data on Ph, SAR, Electrical conductivity (EC), and texture, has
been determined on six test samples .taken at the Allen and t4axwe1l mines.
The results of these tests are as follows.
Allen Mine
. Tests Yrl, 2, 3 Texture - Clay Loam (27% clay) {r`4 Sandy Loam (19% clay)
' A horizon Ph: 7.2 C horizon Ph 7,3
. SAR: 2.3 SAR 6.9
EC 0.9 EC 1.8
B horizon Clay Loam (27°; clay) p & B horizons of R4
Ph 7.4 sample are similar to

The soil was determined to be in the Tab 1e Mountain series. This soil
is an excellent source of topsoil for re-establishing vegetation in
disturbed areas. The average depth of the surface layer (A and B horizons)
r is 25 to 30 inches. A and B horizons can be stock piled together because
1 they are virtually inscperable. If the C horizon is used it should be
• placed beneath the surface layer where possible. This material should
