I made the trip in July 2007, I took the route through Death Valley and Tioga Pass and it took about 8 hours including a couple of rest breaks. The distance was about 400 miles but the roads were quite empty and the scenery was spectacular.
Alabama is about 2,165 miles away from Yosemite National Park. I would recommend flying to a closer city and renting a car to visit Yosemite, or else a drive from Alabama to Yosemite could take as long as 35 hours non-stop.
You can drive through Yosemite in about 2 to 3 hours. This would include driving from the south of the park from Glacier Point through the valley and up to Tioga Pass and exiting to the east.
The drive from Boise to Yosemite Valley, the main part of Yosemite National Park, is 593 miles, or 11 hours. The nearest entry gate to the park, however, is only about 530 miles, or 10 hours away. If you're not up for the full drive in one day, you could stay in Reno for cheap hotels or in Mammoth Lakes to get up and finish the drive to Yosemite in the morning. (I actually just did this drive!)
a little over three hours
Essentially every feature in Glacier National Park was formed by a period of glaciation during the Pleistocene Ice Age, including all the mountains and all the valleys. A look at a map of the park will show several large, long lakes whose beds were scoured out by these glaciers. Some famous and oft-photographed valleys in the park that are easily accessible by car (and on the internet via webcam at www.nps.gov/glac ) are the Lake McDonald Valley, the St. Mary Valley, and the Many Glacier Valley.
