Along the Mormon Trail, the Mormon pioneers established a number of ferries and made trail improvements to help later travelers and earn much needed money. One of the better known ferries was the Mormon Ferry across the North Platte near the future site of Fort Caspar in Wyoming which operated between 1848 and 1852 and the Green River ferry near Fort Bridger which operated from 1847 to 1856. The ferries were free for Mormon settlers while all others were charged a toll of from $3 to $8.
