Comm. 25-020 Feature A Feature A is three oval planting depressions measuring approximately 25.5 meters long (NE/SW) by 6.7 to 14.0 meters wide. The dcpressions range in length from 6.0 to 13.5 meters long, in width from 4.5 to 9.0 meters, and in depth from 60 to 90 centimeters below the surrounding ground surface. The depressions appear to be modifications made to the existing ground surface. It is likely that rock was removed from shallow depressions to make them deeper and larger. The rock that was removed from the depressions was piled along the top rim and outer edges of the depression. There is a 2.0 meter long section along the northwest side of Feature A that is stacked fburto five courses high and is faced (Figure 11). Feature A has been slightly altered by weathering and is in fair condition. Three test -units ('I'U-1, TU-2, and '1 U-3) and nine shovel probes were excavated at Site 19013 Feature A (Figure 12). Feature A Subsurface Testins: Nine shovel probes were excavated in the shallow sediment and rock in the center of the northern most planting depression at Feature A. The shovel probes were approximately 0.5 meters in diameter and were laid out in a grid with two -meter spacing between each probe. The prohes contained a single stratigraphic layer (5 to 25cm thick) of soft, wet, very dark brown (I OYR2/2) loam with 10% small roots and 20% to 30% gravels and cobbles. All of the probes terminated on bedrock and did not contain cultural material. A single test -unit ('I'U-1) was excavated in the south end of the northern most planting depression at Feature A. TU-1 was a 1.0 by 0.5 meter unit that contained a single natural strati graphic layer, was excavated as two 1 Ocm arbitrary levels, and terminated on bedrock at a maximum depth of 22cmbs (Figure 13). Layer 1 was soft, wet, very dark brown (I OYR2/2) loam with 10% small roots and 20% gravels and cobbles. '1'U-1, Layer 1 Level 2 terminated on bedrock and did not contain cultural material (Figure 14). A single test -unit ('1'U-2) was excavated in the central planting depression at Feature A. TU-2 was a 1.0 by 0.5 meter unit that contained two natural stratigraphic layers, was excavated as three 1 Ocm arbitrary levels, and terminated on bedrock at a maximum depth of 32cmbs (Figure 15). Layer 1 (0-21 cmbs) was soft, wet, very dark hroNvn (I OYR2/2) loam with 10% small roots and 20% gravels and cobbles. 21
