Spanish Peaks is in the San Isbel NF. I have exchanged a few emails with Carl Owens who seems willing to help. He doesn't have any better border information but you might ask him if those two peaks specifically are in the wilderness area.

Dwight, I attached a comma delimited file for the Sangre De Cristo Wilderness boundary. I generated it from the DNRGarmin software. The column headings should be self explanatory. The data is in this projection --> NAD83 UTM Zone 13. Its a large file and doesn't exactly match the structure of the sample file. Let me know if this works.......Thks Carl
