San Isabel National Forest - Central Colorado
This particular maps has some pretty good markers for the state of the roads depicted, but as always, back roads can be unpredictable and conditions can change in a storm cycle. Snow is possible in the area at almost any time of year due to the elevation.
The entire state of Colorado has an extensive mining history and this area is no exception. There is scarcely a mountainside with access to the waterways that is devoid of some sort of mining remains.
The high altitudes of the peaks and passes that surround the Leadville area make it home to a number of high elevation endurance competitions. The city of Leadville is the highest incorporated city in the US at 10,152 feet above sea level.
A number of wilderness areas and refuge areas are scattered throughout the area providing vast expanses of solitude and wildlife safety. These areas have a minimal amount of mining "history" lying around.
The Continental Divide zigzags through the area going through some of the highest terrain on the route. A majority of the campgrounds are above 9,00 ft.
Did I mention the altitude?
