Rapid population increases and occupation of Utah by federal troops prompted Mormon leaders to establish migration routes into what would come to be called the Arizona Strip. Jacob Hamblin ventured into the Strip in 1858 after crossing the Colorado River at Ute ford. Hamblin suggested establishing a ferry on the Colorado River at the mouth of Paria Creek, thereby shortening the route considerably. A ferry was eventually established by John D. Lee (Lee's Ferry), however, Buckskin Mountain proved a barrier to using the shorter route. Roads were established over and around the mountain and many of today's highways including state highway 67, US 89 and US 89A follow early pioneer routes.
