I have a pile of Lassen National Forest/Plumas National Forest sheets in front of me. The Harvey Mountain sheet is series 40121-F 1; Poison Lake is F 2; Spalding Tract is F 7. I cannot find these numbers anywhere on the sheets. (OCLC#s 41633824 and 42200314). The Spring Garden topo is series 39120-H 7. (OCLC 41631237). Where can I find a list of these numbers?
