Isabel, these maps were very useful for the ecological studies or natural
resources
studies that I used to be involved with.  They were used to delineate
watersheds,
large ones especially.  They are nice to use in conjunction with the 7.5
minute quads for this
type of geographical work.  The larger physiographic features are convenient
to view on the
15 minute quads (e.g., mountain ranges or large lakes), and the smaller
features are more easily
seen on the 7.5 minute quads.
 
If you do give them up, I hope you can offer them to maps-l folks.
