Like John, my profile is not handy (its at home and I'm not). The climb from Willow Creek to Azotea was I think about 1%. This was to get from the Willow Creek/Chama River watershed to the Amargo Creek/San Juan River watershed. The dividing line also happened to be the Continental Divide.
The original profile was essentially all donwgrade to Arboles, although I think it changed a bit when the relocation was built in 1962. From Arboles, the line was a roller coaster profile of + or - 1.42% to Florida where a constant 1.42% started and continued to just west of Falfa at MP 443.
From Arboles the line left the San Juan River and climbed cross country to Tiffany before dropping down a small valley to the Los Pinos River (not to be confused with the Rio De Los Pinos east of Cumbres!) at La Boca. From there it followed the Los Pinos north to Ignacio then climbed out of that valley and ran cross country dropping into the Florida River Valley. From Florida, the line climbed up the side of Florida Mesa, crossed the top then dropped down Wilson Gulch to Carbon Jct.
Eastbound the grades were in the 1-1.42% range except for 2% stretches from Carbon Jct. to Falfa and from Azotea (between Lumberton and Monero) and Biggs Spur (which is about where the present junction of The Chama-Pagosa Springs highway and the road west to Farmington (Jct. of US 64 and US 84).
End of today's geography lesson, there will be a quiz tomorrow.
