Re: Where was Dalton and/or Broad Spur?

Gordon Chappell's "Logging Along the Denver & Rio Grande" shows the following;
Chama located at MP 342.80
Biggs Jct located at MP 343.57
Broad Spur is shown on the map a mile or so east (Railroad east) of Chama. It doesn't give a MP but I'd guess at around 341. It is between Chama and Lobato, and quite close to Chama.
Dalton is shown on the same map as about a mile east of Lobato.

The map is on page 15, if you have the book. The book is copyright 1971.

Broad appears to have been a pretty small player in the Chama area logging scene, especially compared to Biggs and Sullenburger. Though it mentions that in later years, Broad was one of the principles in the New Mexico Lumber Company at Dolores.
