Fig. 2. Detailed Order 1 soil surveys of the map comparison box from Fig. 1, mapped using different criteria and methods in 1980 and 2002. This area matches the inset shown in Fig. 1. The 1980 mine soil landscape (A) clearly reflects the dominant narrow highwall–bench–outslope landforms typical of pre-SMCRA (Surface Mining Control and Reclamation Act of 1977) steep slope mining techniques. The unmapped areas above and below the mining benches were relatively undisturbed. The post-SMCRA (B) landscape is comprised almost entirely of mine soils with <10% natural soil remaining. Description of the 1980 mapping criteria is given in Table 1 and the 2002 mapping legend in Table 5.
