Hi Jacob, Glen was living and working in a Construction Camp in 1910. His sons weren't with him.
Unfortunately Lincoln Co., Idaho does not have a genealogy society or museum. This is not unusual in Idaho.
You can contact the Idaho State Historical Society, idahohistory.net and ask them to do research on how long he lived in Lincoln Co. Do they have any scrapbooks for Wendell or Lincoln Co. in which he appears? Is he in the City or County Directories?
Hopefully they will have more information. Successful Searching!
