YES...
From my website (pilfered from EZ)
1) Mineral Fork: up until 1983, had a road very much passable by four
wheel drives. In fact there was a pair of old wooden bridges in one spot to
help 10 wheeled dump trucks negotiate the tight, steep switchbacks to access
the Wasatch Tunnel and Regulator mines at the top of the canyon. The
current road was built in 1936, but was actually the third generation road
(the second generation road was built prior to 1899). The bottom of the
present road was badly washed out in '83, taking the banks of earth and the
wood bridges along with it. Apparently the Forest Service never bothered
repairing it (big surprise). Due to the washout and lack of maintenance,
the canyon is open today to ATV's only. I find it wholly ludicrous that the
greatest numbers of registered ATV's in the state is found in Salt Lake
County, yet Mineral Fork is the ONLY legal trail in the ENTIRE COUNTY where
one can drive an ATV. I find this both astonishing and disheartening at the
same time. How can the county expect users to "follow the rules" and "stay
off the foothills", etc., when they only provide 2.1 miles of legal trails
to ride on??
where is Mineral Fork at......? I don't recall seeing this one.
