Several divisions trained at Camp Carson and other installations in Colorado during the war but the "huge monument" you refer may well be the memorial to the 10th Mountain Division, located near the division's former base at Camp Hale. You can contact the division's veterans association. The most current address I have is:
10th Mountain Division Association 5350 Yellowstone Street Littleton, Colorado 80123-1447
Age is irrelevant. Both served during the same general period and records would be equally simple (or difficult) to trace.
