After a little research it appears to be an Ankole-Watusi. Somewhat rare in the US, with a total of around 1,200 here. Must be a gentleman rancher as it was near Telluride.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
