Wow! Those photos load quite fast even for dial up.
The ghost town is being encroached by a gravel pit to the west but the mill site still has some stone walls left of the power plant. This aerial even showed a wye at the junction of the Webb Branch off the trunk, just east of where the line leaves the Navajo River valley and heads south over the flats down to Lumberton. The Webb creek branch went into Webb canyon in 1900-1901.
Only the 6 mile section from Lumberton to Edith was common carrier and was chartered as the "Rio Grande & Pagosa Springs RR in New Mexico", and was considered a Tap Line, using interline freight rates controlled by the ICC, good for Zone rates. Lines east and north of Edith were logging only, except they ran stock cars for sheep and cattle, by contract pricing that was not ICC.
Thanks for the link, now if it was only in color.
