Question: Question: Which president saw the establishment of the recreation area that contains the lower of the San Juan River? Passage:From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing very briefly back into southwest Colorado (within half a mile (0.8 km) of the Four Corners quadripoint) before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons, often over in depth.

The San Juan joins the Colorado in San Juan County, Utah at a point about to the north of Navajo Mountain and northeast of Page, Arizona.
