<br />II. SUh1MARY AP;D CONCLUSION <br />The purpose of this report is to estivate the quantity of <br />natural aggregate in the property. Natural aggregates under- <br />lying the river property are part of the Louviers and Post-Piney <br />Creek alluvial deposits, laid down by the ancestral South ,'latte <br />River. These deposits are preserved in the river floodplain <br />along its ~restern side. Rock debris washed out of the mountains <br />by tfre ancestral South Platte River was reduced largely to sand <br />by the time it reached the general area of the river property. <br />A substantial percentage of the deposits of natural aggregate <br />underlying the river proper' are presently commercial, Eighteen <br />drill holes, frith a totel footage of 579', and an average sample <br />interval of 5.1' !acre completed for this estimate. Samples were <br />analyzed for size gradai:ion in the labo~~atory, and this data was <br />revie~•!ed as part of a geological analysis. <br />Conclusions <br />7.
