According to the manuscript of Martin Parsons, Twistin Dogies Tails Over Rollins Pass, each summer, Mr. Rollins would build a cribbing of logs ... and would fill the center with rocks and earth, which helped reduce the grade between the hills. The original log cribbing can be seen today on the narrow ridge of Guinn Mountain, north of Yankee Doodle Lake. Rollins also built The Junction House, a large, two-story hewd-log structure as a hotel, at the point of intersection of the Berthoud and Rollins roads.
