I like to do the ridge run via Sundance over the the south summit to the main peak.
The first snow in the valley took place Oct 25, 2012 so I decided it would be a good day to climb timp the next day so I could have the place to myself. The snow didn't fill in as much as I hoped amounting to maybe 8 inches or less at 11,000 feet. Started at 6:45 am, made it to Emerald Lake at 10:09 am. By 11:25 am I had crossed the snowfield and climbed to the saddle. From the saddle it took 35 minutes to reach the south summit. Everything was covered in rhime ice. Next it was on to the true summit which I reached at 1:40 pm. I continued on to Bomber peak arriving at 3:26 pm, and from there to N. Timp by 4:28 pm. I took the Cold Fusion Coulior down which was tough going with the snow just enough to make it slick. It was close to 7 pm when I made it to the dirt road, and was lucky enough to hitch a ride with some hunters.
July 4, 2010. Went up the snowfield from Emerald Lake. Took 45 minutes to reach the saddle and another 15 minutes to reach the peak.
Was on top before 9 pm and was able to catch the sunset. The views were amazing. I could see the Great Salt Lake to the NW, Utah Lake to the West, Jordanal Dam to the NE, Deer Creek Resevoir to the East, and Mt Nebo to the south.
August 9, 2008 - Went up the Aspen Grove trail to Emerald lake (that took 1 hour 45 minutes), continued on to Roberts Horn (from the lake this took 1/2 hour). Descended back to Emerald Lake and climbed the snow field to the saddle (Lake to saddle took 1/2 hour), then I summited South Timp (in 15 minutes from saddle), then descended and ascended Timp (in 40 minutes from saddle). I returned via the snowfield and the Aspen Grove trail. Big day and another of my solo trips.
Approached via Timpooneke and camped in Timp Basin. Descended via the "glacier". I had to hurry to the peak and back from the glacier saddle because of questionable weather. Saw a herd of mountain goats at Emerald Lake that let me get close-up photos.
