27-May-2013 -- After visiting [42,-111] and the nearby ID-UT-WY tripoint, I crossed back into Wyoming, then spent the next two hours passing back and forward between Wyoming and Utah - crossing the Wyoming-Utah state line more times than I could count. (The final crossing occurred just a few hundred feet before the confluence point, which only barely lies within Wyoming.)
I was able to reach the confluence point just before sunset, thanks to the directions provided by the previous visitors (the Lincolns), who noted the gate at [40.98597,-111.00493]. This 'gate' is actually just a part of a fence where people (presumably, farm workers) have repeatedly driven over it, knocking it flat. I parked here, and hiked the remaining 1 mile to the confluence point.
What I was not expecting, however, was how much climbing I would have to do during this 1 mile hike. The Lincolns referred to this as "moderate terrain", but in fact, reaching the confluence point required climbing up a significant ridge. (The almost 8000 foot elevation made the hike feel even more strenuous.)
The confluence point itself lies near the top of a rock-strewn ridge. At this time of year (spring), several pretty alpine wildflowers were growing nearby.
