The East Inlet Trail was one of the more difficult trails in Rocky Mountain National Park during the early part of the 20th century, but it still drew travelers due to the scenic beauty along the way.  The dangerous nature of the trail led to Depression-era funding for improvements with Public Works Administration labor.  Dry rock walls and intricate bridge abutments were constructed in the early 1930s and allowed for continued use by tourists to the Park.  In 1940, Civilian Conservation Corps crews made further improvements that sustained the trail through the rest of the 20th century.
