During this six-month period, Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) samples were collected from approximately 60,000 locations in the Rocky Mountain states and Alaska. To date, all of the LASL Rocky Mountain region has been sampled at a nominal density of one location per 10 km/sup 2/, and 65% of Alaska has been sampled at nominal densities of either one location per 23 km/sup 2/ (flatlands) or one location per 11 km/sup 2/ (mountains). Also during the report period, water samples from 13,771 locations were analyzed for uranium by fluorometry or delayed-neutron counting (DNC). Water samples from 12,993 locations were analyzed for 12 other elements by emission spectroscopy. Sediment samples from 8820 locations were analyzed for uranium and 31 other elements by combined DNC and neutron activation analysis. Sediment samples from 22,696 locations were analyzed for two additional elements by x-ray fluorescence. No data are given. Fourteen LASL reconnaissance reports, one pilot study data release, one quarterly progress report, and a manual of LASL HSSR field procedures were open filed by the Department of Energy, Grand Junction Office.
