Ken - I was at the CRRM today and tried to find out what I could about Weston. There is another town in Los Animas County by the name of Weston. I however might have a lead on the Weston you are looking for. I need to get ahold of the Colorado Historical Society and check with them. At the museum I checked the Colorado & Southern (Denver South Park and Pacific) ICC Valuation Maps and did not find Weston. However the maps were made after Weston shut down. I the colorado geographical name listing I did find a "Weston Pass Ranch".It showed Latitude and Longitude coordinates. I will check and see if this is one in the same.
