bedrock outcrops along the stream bed not very far upstream or downstream from the location of the spring. The flow takes place along a 100 to 200 feet stretch of the creek where the drainage appears to follow a joint whose trace is also marked by a cliff northeast of the spring (see Surface Geology and Top of Brookside Coal drawing, in map pocket). The cliff and liniation due to the joint trace are easily seen in the aerial photo of the area. The spring has a discharge of approximately 1 to 2 gpm (table 2.04.7(1)-2). 3.0 Spring TP-S3 The spring is located along the unnamed tributary to South Oak Creek about 150 feet upstream from the confluence. Like TP-S2, it is localized to a short stretch in the creek even though there are other spots along the stream bed where the valley fill is eroded away and the bedrock is bared. Moreover, this spring is northeast of TP-S2 which is also the trend of the . dominant joint set that controls TP-S2. It is likely that the two may be interconnected by joints that reach down to the same perched aquifer. Flow is estimated at 1 to 2 gpm. At the time of the field investigation in early May, dampness was observed in a weathered coal and carbonaceous shale bed along a cut west of old Twin Pines No. 1 Mine. There was no evidence to suggest that this dampness amounted to flow as a spring at other times. Other springs are reported to exist near the southeast corner of section 35 (drawing of General. Mine Area) but these have not been examined in the field as the Cedar Canon Mine road was closed to traffic at the location of TP-S1. It is worth noting that the area that includes the channel of South Oak Creek just downstream of the confluence of this creek with the unnamed tributary has been highly disturbed by past surface mining activity. In the westernmost pit, a pool of water stands at the bottom at a depth of 50 to 60 feet below the 10 natural channel surface. It appears that impervious beds in the JFSA-34
