Killyon Canyon, Emigration Canyon

The Road

            The road through Killyon Canyon continues up the main drainage of Emigration Canyon beyond the turn off for Burr Fork.  The road is paved for the first ¼ mile.  Beyond this point it is a well maintained dirt road that provides access to homes in the Killyon’s Subdivision.  At one time the road extended beyond this point, through Killyon Canyon and over the ridge into East Canyon.  However, the road is currently barricaded at the end of the Killyon’s Subdivision preventing the passage of vehicles beyond this point.  The original route the road followed has become completely overgrown throughout much of its length.  From the barricade, the trail up Killyon Canyon sees occasional use by off road vehicles, but is primarily used as a hiking trail.  The hiking trail through the canyon is a narrow single track trail that, in many places, follows a different route than the original road followed.

Criteria*

"The right-of-way for the construction of highways over the public lands not reserved for public uses, is hereby granted."

Construction:  "Means an intentional physical act or series of intentional physical acts that were intended to, and that accomplished, preparation of a highway by a durable, observable, physical modification of land for use by highway traffic." 

This road was originally constructed by John Killian to access timber in Killyon Canyon.  It also formed "Killian's Cutoff," a shorter route from the Mormon Trail at Big Mountain into Emigration Canyon.

Highway: "Means a thoroughfare that was prior to the latest available date used by the public, without discrimination against any individual or group, for the passage of vehicles carrying people or goods from place to place."

This was a route from Killyon Canyon to the base of Big Mountain that was utilized by settlers moving into the Salt Lake Valley.  It was also used to access timber in the canyon and bring it to mills located in Killyon's Canyon and at the foot of Big Mountain.  This road was passable by four-wheel drive vehicles up until the flooding that occurred in 1983.  There are several parcels of private land that are accessed by this route.  However, if these land owners are successful in their bid to have their land preserved as open space, this route will no longer serve any transportation need.

Unreserved public lands:  "lands owned by the United States...that had not yet been set aside, dedicated, withdrawn, reserved, settled, preempted, entered, appropriated, or disposed of, or on which claims had not been located."

Only a small stretch of this claim crosses land reserved as part of the Wasatch National Forest.  Since construction would have taken place in the 1850's the land it crosses would have been unreserved at that point.

History

In 1852 a grant was awarded to Daniel H. Wells that gave him “exclusive control of the canyon for opening a road to the public, toll authorized.”  Shortly after receiving the grant Wells was called away for other duties.  While he was away he left the work of constructing the road and collecting tolls in Emigration Canyon to his assistant John “Killman.”  Approximately a year and a half after the first grant was awarded, John Killian was given a similar grant for the canyon.  It is believed that the John “Killman” recorded in the original grant is actually the same person as the John “Killian” that received the second grant.

            The grant obtained by John Killian gave him control of the upper reaches of Emigration Canyon.  This consisted of an area beginning about 5 miles from the mouth of the canyon and extending to Mountain Dell.  The road that he had constructed followed the drainage up the canyon, climbed up over the ridge and descended to the base of Big Mountain.  This road not only provided access to the timber on the other side of the ridge, but also connected with the Mormon Trail forming Killian’s Cutoff.  While this route was somewhat shorter than the original Mormon trail, it was infrequently used.  The original trail provided better campsites and easier access to water.

            In 1858, Appleton Milo Harmon built a sawmill at the foot of Big Mountain.  It is likely that the lumber cut in Harmon’s mill was hauled out of Killyon Canyon by way of Killyon’s Cutoff.  It is thought that the logging that was taking place in Emigration canyon was sufficient to remove a large portion of the trees, forever changing the composition of the vegetation in the canyon, and clearing the way for the “Sheep Driveway” that was to come.

            In the 1870’s the Mormon colonizers began to utilize the high valleys of the Wasatch Mountains for the grazing and raising of their sheep.  During the warm summer months there was more than enough vegetation for them to eat.  However, during the winter months the sheep had to be brought down to lower, warmer elevations.  The sheep were moved to and from the Salt Lake Valley along the “Sheep Highway.”  There were two different variations of this highway.  The north branch, called the Big Mountain Trail, went up Killyon Canyon to Mountain Dell, and then over Big Mountain and into East Canyon.  The south branch, the Little Mountain Trail, left Emigration Canyon and went over Little Mountain, across Mountain Dell and then up Alexander fork to Parley’s Summit.  By the 1950’s with increasing development and regulation of grazing the Sheep Driveway was closed and the annual migrations were brought to an end.

            The road up Killyon Canyon and down into Mountain Dell saw continued use into the 1980’s as a jeep trail.  In 1983 an unseasonably warm spring brought on a rapid snow melt creating flooding throughout the valley.  The flood waters that were running down Main Street in Salt Lake City, were also wreaking havoc on the jeep trail up Killyon Canyon.  The high water flow eventually eroded away the river bank, undermining the road in places.  Along certain stretches the water actually jumped the bank and began to flow down the road, creating a channel much deeper than the one it originally occupied.  These floods effectively prevented vehicles from using the road through Killyon Canyon.  From this time on the jeep trail has only been accessible on foot or with an off-road-vehicle.
