I understand the need for conversation and taking care of the earth, but I would think that they ought to improve on this road. Its an accident just waiting to happen. As you drive you the first thing that really grabs you attention is Lambert Dome.
A hunk of granite rising from the floor of Tuolumne meadows,its hard to miss. Especially as it is contrasted with the lush green meadows that for over half the year are covered with snow.
Somewhere between there and the valley floor is a turnoff for May Lake. Don't miss it. Its a mile hike to the lake which serves a base for all sorts of destinations. The path goes uphill, but don't give up hope around the corner is some of the prettiest country California has to offer.
If you visit Yosemite make sure to visit, its well worth the time!
