Mount Lemmon Highway s(u)+(ow)

This is the most famous item in "Arizona's Trifecta of Out and Back Mountain road  climbs". It's not the steepest. But it is the highest completely paved climb, and I think it is  also is the most scenically interesting of the paved parts of the the three. Interesting light conditions on the particular day, that I did this ride, played a role in this impression.

Topologically speaking, there are a few more points to mention. An old, unpaved road from the north meets the upper portion of the new highway. So there is actually a two-way summit, not far from where the two meet, located on the new highway. I is bikable, but compared to the out and back climb on the paved road, biking this is a rare experience indeed. But even the modern highway descend more than 300ft from an unnamed summit point where Whitehorse campground is located, before meeting the old gravel road and then climbing to the top of the out-and-back summit. I am calling that point near Whitehorse campground Mt Lemmon Highway s(u), and I am listing two crossings of Mt Lemmon Hwy s(u), for a ride that is really a completely paved ride out and back to Mount Lemmon(ow). This is to be consistent, and apply the same rules for what makes a summit crossing for much smaller summits.

Approaches

From South.
The most obvious way for the lower approach is a rare thing in greater Tuscon, a road that runs diagonally to the square grid pattern of the city, appropriately named Catalina Highway. But the profile approaches instead from the south on a road with less traffic through an area filled with real estate dead end roads, named Soldier Trail. You can see the initial traverse up the ridge straight ahead.

When coming back down in the last light of day this fast, last decent, it feels like a plain finally approaching a runway. The a grid pattern below, highlighted by points of light in the dusk, is made up of real estate investments. But going up this same section is just the initial warm up to a long climb. The entire road is engineered with wide lanes, uniform grades that never get extremely steep. In almost all places the road has a fairly wide shoulder without rumble strips. The first fine far views come a few miles after the first NF campground. This is the rocky world of Thimble Peak, Rose Peak and the canyons leading up to it from the south. Amongst the many vista-pulloffs, the most popular one with motorists seems to be Windy Point. Not slighting its scenic beauty, maybe one big reason for this is the presence of toilets. Actually - this is the beginning, of what to me is the most interesting part of the road. A switchback leads up onto a ridge, with a far view direction east, which is especially fascinating during late light, but also a view west and the world of rock towers, and piled up rocks through which the road negotiates its way upward with one long ramp into a higher world of trees and shade.

Between here and the top you have to look for the far world below through port holes in a a dense forest. An exception to this is the first view west into the vastness of the San Pedro Valley. The highest point of the two way summit is reached near the turnoff to the Whitetail campground.



             


From North. (described downwards) A 400ft drop and another small hill leads to the turnoff down the signed turnoff onto the gravel road to Oracle.

The Out-And-Back Summit to Mount Lemmon.

Near the Oracle turnoff the road traverses for a while along a sometimes open ridge with views direction Oracle. Then the rest of the climb to the peak is in dense forest. The small collection of ski-homes in Summerhaven is a very short downhill off the road to the peak itself.

Road signs do a fine job in understating the climb to the top of the mountain, and thus coaxing the rider all the way to the top, by understating the amount of effort required. The signs only specify the distance to the bottom of the ski area, but do not mention this fact. Granted - this is not Vail Mountain, and that is a good thing for many reasons. Once you get to the tiny parking area in the forest, it is only another 1.5 miles of steep climbing to the top of Mount Lemmon.  The rest of the climb may not a actually be that hard, but after 7000ft of climbing to get here, it sure seemed that way. On a 6th of December it was the only stretch of road with remnants of snow, next to the road but not on it. The road ends on top of the peak in the forest, at an observatory. If there are far views from here, it takes a while to walk to them. A much better vantage point is not so obvious. It is not at the various pay-parking lots , but instead at the unpaved turnoff to the previous observatory, a small distance below the summit - great views in 180 degrees. Some of the pictures in the slideshow were taken there.

PARTIALLY PAVED / UNPAVED

( < Tumomac Hill Rd(ow) | Mt Lemmon Rd via FR4450(sh) > )

Mt Lemmon Highway s(u) x2: Reddington Canyon ~5miles from its jct with Tanque Rd > Reddington Rd west with several unwanted dead end detours > Soldier Trail[a road] north > up Mt Lemmon Highway > Mt Lemmon Highway s(u) <> short out and back to Summerhaven <> separte out and back to Mt Lemmon(ow) >> Mt Lemmon Highway south > Mt Lemmon Highway s(ui) > Soldier Trail south > back to starting point on Reddington Rd ~5miles from jct with Tanque Rd: 79.1miles with 9090ft of climbing in 7:57hrs (garmin etrex32x r4:24.12.05)
Notes: contains 2 miles of unpaved approach to road from campsite. - Definitely the biggest climb I have ever done in December. Moderately cool decent from 9000 to 6000ft, but very bearable ~3pm. Perfectly comfortable after that. Highs in Tuscon was 75 degrees.
