Dave and all,
A 50% size reprint of the 1917 Valuation maps for Leadville for the D&RG are avilable from the Colorado Railroad Museum. This includes the Blue River, Ibex and Graham Park Branches
The CRRM folks are also working on a book of maps from the C&S Valuation of Leadville and the High Line as well.
The C&S maps for Leadville are a total of 6 maps. Three for Leadville proper including the Bon Aire spur, and three more of the Leadville Mineral Belt Railway. There are are three (as the C&S refers to them) "Draw-overs" in Leadville alone. The draws would make for some interesting switching moves since they are on straight track. The Leadville Mineral Belt and some (but not all) of the C&S tracks in their Leadville Yard are 3-rail at that time, owing to the C&S joint ownership of the CM.
