I believe that one of the sporting goods stores in Lone Pine sells USGS 7.5' maps. You might also try either the ranger station in Lone Pine or the InterAgency Visitors Center south of Lone Pine at the junction of Hwy. 395 and 136. If you happen to be in Southern California, Allied Map Services, 966 N. Main St., Orange, is a USGS stocking dealer. If not, the USGS web site (
www.usgs.gov) has a search to locate stocking dealers. They call them "business partners". If you use the USGS site, be patient. Their server is slow. Good luck!
