"I did not know Mt Conness could be reached from the west side without mountaineering equipment."
The west face is indeed a high angle climb, but that's not where we are talking about. From the Young Lakes, you go up to Unnamed Lake 10598 which is due south of the peak. From there, you scramble up the talus slopes and a high valley. Then for the last few hundred yards, you are approaching the summit along the southeastern ridge. I've dragged dozens of newbies up there. The problem is that the summit area is tiny, and there is room for only three or four people at a time.
Roosevelt Lake is OK in mid-day, but it doesn't have the best view of either sunrise or sunset.
"The Shot" is done by camping by the Middle Young Lake or else the Upper Young Lake, and you aim west to catch the first rays of sunrise hitting the top of Ragged Peak in the west with a water reflection in the foreground. But, what do I know?
