Hello,
Here's an elevation profile for the Colorado Trail: gif format, pdf format
The route includes the "Cataract Ridge Reroute", "Clear Creek Reroute" and the "Cache Creek Cutoff".
This is the first draft. So the mileage has not been calibrated with the databook, or any official sources. Eventually I'll make a better version, but I thought I'd post this one anyway.
