Does anyone have information on the D&RG tracks at Crested Butte?

Hello, new member making my first post here, so hi!

Moving on, I'm building a freelance model railroad that interchanges with the D&RG at Crested Butte, CO. I am currently searching for information regarding the track arrangements the D&RG had there because of this. I looked up the Sanborn maps of Crested Butte on the Library of Congress website, but as far as I could see, they didn't have any of the D&RG's tracks marked on them. So, I finally joined the forum here to ask if anyone could help me find resources to help fill in the blanks. Track plans and/or valuation maps would be great, as would website or book recommendations that might have more information, but any information you might be able to provide would be great.
