I have a collection of Colorado maps too. They are in JPG format so it's easy to view them. Maybe we could set up some sort of CD swap between us. Odds are there are a lot of duplicates but there may something new. I might also be able to set up an FTP server if you guys have good internet access.
I haven't looked at my maps in a while. I chased some stage stops down only to keep finding they were on private land or other some interesting areas that were pretty hard to nail down within a few miles on a modern map. It can be a challenge. But it can also be interesting when you find a historic spot along a road you've driven for years and had no idea of some of the events that happened in the past. Naturally most of the Denver area spots have been covered by new construction.
That's a good idea. Also I have some Excel worksheets that are BIG. One has ~47,000 Colo Placenames as shown on USGS maps. In addition I have combined Lat/Long, altitude, county, etc so anyone can plug into a Google map to locate them.
The 1894 map I've scanned in twelve sections on my large format scanner. Saved them as TIFF until I modify some part or copy.
Much of my stuff is copyright protected so am unsure about how to work around that. For PTP transfer or CD's to friends I don't worry about that.
I knoe a couple guys who travel the DEnver area daily, in different routes, who keep up to date on orighinal section sidewalk repairs, teardowns, HUDs, etc and detect what they can.
Biggest problems I had were computers crashing, HD problems, and am working with four drives now. Trying to recover bits and pieces from them.The maps are OK, which is great as they are a PITA to copy. Especially from publications. Some reference books I use a lot I just sawed on my bandsaw into seperate sheets. Not my really good books.
My research starts with a location name or tale. I find what I can online and some books to get core info about it. Then I Google [actually AcmeMapper] and mark areas to search as well as GPS data. Print a 4x6 color pic of what I need. Maybe terrain or Topo are better but always an Earth view. Then we go hunting.
I take pics at the sites for future referral if we want a return trip there. Mostly how to get there and get back. Sounds easier than is. Old maps and new maps seldom agree. Names change, counties change, roads disappear, new roads appear and no visible landmarks to sort out where you are.
You can PM me if you'd like and lets chat about it? I'm in Broomfield, retired and can meet for coffe & donut if that works??
