If they are shiny and smooth they could be quartz, plagioclase or feldspar.  All are present in the granitic/diorite gneiss bedrock around Lake Martin.  They are all blocky shaped minerals but can be rounded and smoothed due to weathering.  Interestingly the reddish soil around Lake Martin is what is known as residual soil which forms from the in-site chemical weathering of the bedrock.  Not your typical sedimentary rock that is weathered into small particles, transported by water and deposited like you would see with sandstones, silts, etc.  The outcrops are bedrock types that are more resistant to weathering.
