I'm processing a 1:24,000 topographic map from Icehouse Canyon, Colorado, 1978 edition published in 1978. The weird thing is that it has a star next to the year published. I don't think I've ever seen this before on a topo. map (congressional hearings, yeah). Is there a special significance? Carlos A. Diaz Government Publications, Maps, and Microforms James E.
