This aerial photograph shows the location of the original ferry crossing, at the narrow point of the river between the red and blue asterisks. This is also the location of the modern boat launch (red asterisk), as well as the USGS gauging line, which measures the flow of the Colorado River as dictacted by the 1922 Colorado River Compact between the seven states which benefit from diverted Colorado River water. The blue asterisk denotes the beginning of the rough ledge of the Shinarump congolmerate, a steep and craggy formation rising above the river, visible here as the light colored strip between the river and the red sandstone. During the ferry days, the wagon route for travelers across the Colorado ran along this formation for one and a half miles. Despite attempts to level the hard rock, the road was so difficult that it was proclaimed the worst stretch of frontier road in the west, and nicknamed "Lee's Backbone."  The green strips of vegetation along the river are dominated by exotic tamarisk.
