Great late summer trip to the Leadville, CO area. Weather was sunny and mild. 500 miles driven and 77 miles of hiking over 7 days. After leaving I-70 and driving over Fremont Pass (11,318'), you descend into the Arkansas River Valley where I spent almost the whole trip. The bottom picture is the Upper Arkansas River. It flows 1469 miles (6th longest in US) until it joins the Mississippi in southeast Arkansas.
